#  Executive Summary {#executive-summary .unnumbered}

*Introduction*. The Federal Communications Commission's Laboratory
Division has completed a second phase of its measurement studies of the
spectrum sensing and transmitting capabilities of prototype "TV white
space" devices. These devices have been developed to demonstrate
capabilities that might be used in unlicensed low power radio
transmitting devices that would operate on frequencies in the broadcast
television bands that are unused in each local area. At this juncture,
we believe that the burden of "proof of concept" has been met. We are
satisfied that spectrum sensing in combination with geo-location and
database access techniques can be used to authorize equipment today
under appropriate technical standards and that issues regarding future
development and approval of any additional devices, including devices
relying on sensing alone, can be addressed.

The Commission is conducting a rulemaking proceeding to consider
authorization of new, low power transmitting devices in the television
broadcast spectrum at locations where channels are not being used for TV
or other authorized services (ET Docket No. 04-186). This locally unused
spectrum is often referred to as "TV white space." As established thus
far by the Commission, white space devices (WSDs) that operate from a
fixed location will be allowed into the TV spectrum simultaneous with
the completion of the transition from analog to digital television
broadcasting on February 17, 2009. This action will open for use a
significant amount of spectrum with very desirable propagation
characteristics that has heretofore lain fallow. It will also allow the
development of new and innovative types of unlicensed devices that
provide broadband data and other services for businesses and consumers
without disrupting the incumbent television and other authorized
services that operate in the TV bands. The Commission is considering
whether to also allow "personal/portable" WSDs to operate in the TV
spectrum.

One of the principal considerations in the white space proceeding is how
to reliably determine the availability of unused frequencies in local
areas. A number of parties participating in the proceeding have
suggested an approach for identifying unused frequencies whereby a WSD
would employ a "listen before talk" or "detect and avoid" strategy. This
approach would use "spectrum sensing" techniques that listen for the
signals of TV stations, wireless microphones, and other incumbent
services. The Commission has requested comment on whether to require
that the sensing capability of devices using this approach be able to
detect signals as low as ‑116 dBm, or some alternative value. A second
technical consideration in this matter is the potential for WSDs to
interfere with TV reception and wireless microphone operations. To
address these issues, the Commission announced that it would perform
testing of the spectrum sensing and transmitting capabilities of the
prototype WSDs.

The purpose of the testing program is to provide additional information
for the record that will be considered along with other information in
developing the Commission's final decision on white space devices. The
tests are not intended for equipment authorization or to determine
whether the devices would comply with any possible standards that the
Commission might adopt. Rather, they will provide information in support
of the Commission's action in this matter. Initial tests (Phase I) under
this program were completed in July of 2007.[^1] This report describes
the tests performed during the second (Phase II) series of tests and
provides a compilation of the results of measurements of the spectrum
sensing and transmitting functions of various prototype WSDs.

In October 2007, the Commission's Office of Engineering and Technology
(OET) issued a Public Notice announcing that it would perform additional
laboratory and field tests of white space devices and invited interested
parties to submit such devices for testing at the FCC Laboratory in
Columbia, Maryland.[^2] Subsequently, OET issued a second Public Notice
announcing that the second phase testing would begin on January 24,
2008.[^3]

*WSD Prototype Devices Submitted for Evaluation*. Five devices were
submitted for examination in the Phase II tests. These devices were
provided by Adaptrum, the Institute for Infocomm Research (I2R),
Microsoft Corporation, Motorola Inc., and Philips Electronics North
America (Philips). These devices are not intended as actual consumer
products but rather are development tools for evaluating the viability
of spectrum sensing and potential interference. They do not communicate
with other devices. Not all tests were performed on all devices. For
example, the Microsoft device was available only for limited tests in
the laboratory and the I2R device was submitted after the initial tests
were completed.

*Spectrum Sensing for TV Broadcast Signals*. This portion of the study
examined the ability of the WSDs to detect whether channels are occupied
by ATSC (digital) TV signals. All of the prototype devices had
capabilities for detecting TV broadcast signals on UHF channels 21-51,
the operating range of the prototype devices. The tests were initially
performed in the laboratory under various controlled conditions.
Spectrum sensing sensitivity to clean digital TV signals in isolation
and also in the presence of other TV signals on adjacent channels was
measured. In addition, sensitivity tests were performed using recorded
TV signals to simulate "real world" conditions. Spurious emissions
generated by the prototype WSDs were also measured. The laboratory tests
were followed by field tests at nine sites in Maryland and the District
of Columbia to evaluate the DTV sensing performance.

*Spectrum Sensing for Wireless Microphones*. The wireless microphone
portion of the testing looked at the ability of the WSDs to detect
wireless microphones authorized under Part 74 of FCC rules. Microsoft,
Philips and I2R indicated that their devices were capable of sensing
wireless microphones. Tests of this capability were initially performed
in a controlled environment in the laboratory. Those tests were followed
by field tests at two sites, one in Maryland and one in New York City,
to evaluate the capability of the devices to detect wireless microphones
under field conditions.

*Transmitter Characterization and Interference Testing*. The Adaptrum
device included transmitting capability.[^4] Laboratory tests were
performed to characterize the transmitter's signal, which is an
important element for assessing the interference potential of WSD
devices. Field tests were also performed to evaluate potential
interference from the Adaptrum transmitter; however, these tests were
limited.

**[Observations:]{.underline}**

-   All of the devices were able to reliably detect the presence a clean
    DTV signal on a single channel at low levels in the range of -116
    dBm to -126 dBm; the detection ability of each device varied little
    relative to the channel on which the clean signal was applied. These
    measurements did not take into account the antenna that would be
    used with personal/portable devices.

-   The detection threshold sensitivity of the devices varied from -106
    dBm to -128 dBm when recorded off-air DTV signals, which included
    multi-path fading and other "real-world" distortion, were used. The
    impact on detection ability varied considerably among the WSDs and
    with the characteristics of the different recorded signals.

-   Several tests were performed with DTV signals present in adjacent
    channels. These tests showed that in the presence of
    moderate-to-strong signals in a first adjacent channel, the
    detection threshold sensitivity of all of the devices was severely
    impacted. For some of the devices, the degradation in the detection
    sensitivity was as much as 60-70 dB. In some cases, the degradation
    was such that the detection threshold could not be measured. This
    could impact significantly the ability of the devices to reliably
    detect TV signals within stations' service areas.

-   The Microsoft, Philips and I2R devices were tested for their ability
    to sense for the presence of wireless microphones (both FM/analog
    and digital) operating within UHF TV channels. With no other signals
    present, the devices were able to detect wireless microphones at
    levels ranging from -103 dBm to -129 dBm depending on the type of
    microphone, and the device. In the presence of DTV signals in
    adjacent channels, the detection threshold was degraded such that it
    affected the ability of the devices to reliably detect the
    microphone signals.

-   Scan time for the devices varied from 0.1 second per channel
    (Motorola) to 185 seconds per channel (Adaptrum). The Adaptrum
    device was modified during the tests and its scan time changed from
    37 seconds per channel to 185 seconds per channel.

-   Channel Occupancy (TV sensing) field tests were performed at nine
    locations for the Adaptrum, I2R, Motorola, and Philips devices.

    -   In most cases, the devices correctly reported channels as
        occupied when the device was operated within the service contour
        of the stations broadcasting on those channels and viewable
        signals were observed on the channels.

    -   In some instances, the Adaptrum, I2R, and Motorola (in sensing
        only mode) devices incorrectly reported channels as unoccupied
        (available) when the WSD was operated within a station's service
        contour and the signal was viewable.

    -   All of the devices reported some channels as occupied when the
        WSD was operated outside of the service contours of stations
        broadcasting on those channels whether the signal was viewable
        or not.

    -   The Philips device generally reported most channels occupied,
        whether the WSD was operating inside or outside any service
        contours whether the signal was viewable or not.

    -   During the field tests, the Motorola device's
        geolocation/database feature was used in combination with its
        sensing capabilities. In those tests, the Motorola device
        correctly reported all occupied channels used by stations within
        whose contours the WSD was operated.

-   Wireless microphone sensing tests were performed using the I2R and
    Philips devices at two field locations. The tests were conducted
    first with microphones off, and then turned on, in pre-determined
    channels to determine if the devices could sense the presence of
    wireless microphones. At both sites and all the test locations, the
    Philips device reported all the channels on which the microphones
    were designated to transmit as occupied whether the microphone was
    transmitting or not. The I2R device indicated several channels as
    available even when the microphones were on.

-   The Adaptrum device's transmitter was characterized in the
    laboratory and was used to investigate interference potential to DTV
    signal reception. Anecdotal tests demonstrated that co-channel
    interference would occur at line-of-sight distances of up to 360
    meters at an EIRP of approximately +7 dBm when the DTV was receiving
    a weak signal using a receive antenna at a height of 9.3 meters. No
    interference was observed when the Adaptrum device transmitted on an
    immediate adjacent channel even with the transmitter in close
    proximity to the receiver with a roof-top antenna. No other
    configurations were tested for interference.

-   Anecdotal tests were performed at two field sites to assess the
    interference potential from WSD transmitters to cable television
    reception via direct pick-up of signals by cable system components.
    These tests showed that under certain circumstances, when the
    transmit antenna was placed in close proximity to a cable connected
    TV, direct pick-up interference was observed. The direct pick-up
    interference potential appears to be highly dependent on the
    interconnection among various system components (*e.g.,* cable
    amplifiers, splitters and set-top boxes) being used.

# Introduction

The Federal Communications Commission's (FCC) Laboratory Division has
completed the second phase of its program to measure the spectrum
sensing and transmitting capabilities of devices intended to operate on
frequencies in the broadcast television bands that are unused in each
local area. These so-called "white space devices" (WSDs) have been
developed to demonstrate features that might be used in unlicensed low
power radio transmitting devices.

This measurement project was undertaken in support of the Commission's
pending consideration in ET Docket No. 04-186 on whether to permit low
power radio transmitting devices to operate on an unlicensed basis in
the frequency bands that are currently allocated to the television
broadcast and certain other licensed services.[^5] Such low power
operations would only be allowed on frequencies that are not used by TV
stations or other licensed services in each local area. These unused,
*i.e.*, vacant or "available," frequencies in local areas are often
termed spectrum "white spaces." As established thus far by the
Commission, fixed white space devices (WSDs) will be allowed into the TV
spectrum simultaneous with the completion of the transition from analog
to digital television broadcasting on February 17, 2009. This action
will open for use a significant amount of spectrum with very desirable
propagation characteristics that has heretofore lain fallow and will
allow the development of new and innovative types of unlicensed devices
that provide broadband data and other services for businesses and
consumers without disrupting the incumbent television and other
authorized services that operate in the TV bands. The Commission is
considering whether to also allow "personal/portable" WSDs to operate in
the TV spectrum.

The Commission is considering two categories of devices for unlicensed
operation in the TV white spaces.[^6] The first category consists of
low-power "personal/portable" WSDs that will function similar to WiFi
transceivers in laptop computers, and wireless in-home local area
networks (LANs). The second category consists of higher-powered
"fixed/access" WSDs that would typically be operated from a fixed
location and might be used to provide a commercial service such as
wireless broadband access. As established previously by the Commission,
fixed white space devices will be allowed into the TV spectrum upon
completion of the transition from analog to digital television
broadcasts on February 17, 2009.[^7] The Commission is now considering
whether to allow non-fixed "personal/portable" WSDs to also operate in
the TV spectrum.

An important consideration in the proceeding is how to ensure that
unlicensed devices operate only on vacant frequencies. One approach
under consideration is for the WSD to employ "smart radio" features that
would use a "detect and avoid" or "spectrum sensing" strategy. An
alternative approach would rely on accessing a database of licensed
services to identify active services near the device's location. The
device location would be determined by an integral geo-location
technology, such as GPS. This technique is commonly known as a
"geolocation" detection approach. A second issue is the potential for
signals transmitted by a WSD to cause radio frequency interference (RFI)
to incumbent users of these bands (*i.e.*, TV reception and wireless
microphone operations). The Commission indicated that it would test
prototype devices to collect technical information regarding both of
these issues.

Consistent with the Commission's plan for white space testing, the
Office of Engineering and Technology (OET), through its Laboratory
Division, performed initial tests of two prototype devices and issued a
report on the results of those tests in July of 2007.[^8] Subsequently,
on October 5, 2007, OET issued a Public Notice inviting submittal of
additional prototype devices for further tests (Phase II).[^9] On
January 17, 2008, OET issued a test plan for the Phase II tests to help
ensure that the testing would be open to outside observers, and
announced that the testing would commence on January 24, 2008.[^10]

Five parties responded to the announcement of the Phase II testing and
provided prototype WSDs to the Laboratory for testing: Adaptrum, the
Institute for Infocomm Research (I2R), Microsoft Corporation
(Microsoft), Motorola Inc., and Philips Electronics North America Corp
(Philips).[^11] The Microsoft devices malfunctioned during the test
process and were not replaced. The I2R device was submitted after the
initial laboratory tests were completed. As a result, not all the tests
were performed on these two devices. All of these prototypes have a
sensing capability, but only two (Microsoft and Adaptrum) have a
transmitter. Since the Microsoft device malfunctioned before the
transmitter tests were performed, its transmitter was not used in any of
these tests.

This report describes the tests and measurements performed on the
prototype WSDs and the results obtained, with focus on impacts to
broadcast television and wireless microphone operations. In particular,
this report provides the results of tests of the spectrum sensing
capabilities of the prototype devices as a means for identifying TV
channels unused by TV broadcast or wireless microphone operations and,
where the devices included transmission capability, their emission
characteristics and potential for causing interference to those
services. While other incumbent services operate in the TV bands, those
services are not specifically being examined in this test program as the
Commission has proposed other methods for protecting them from WSD
operations.

## Test Scope and Approach

The Phase II tests first examined the devices in the laboratory under
various controlled test conditions. The WSDs' ability to sense DTV
signals was evaluated in several ways: using a single DTV signal, with
two DTV signals (one placed on an adjacent channel), and with recorded
RF captures that exhibit various signal fading conditions. Similarly,
for those devices capable of sensing wireless microphones, tests were
performed with wireless microphones alone and with DTV signals present
on adjacent channels. The wireless microphones were operated on various
frequencies within a TV channel (both near the center of the channel and
near the edges).

In preparation for the field tests, the performance of the devices in
sensing off-the-air signals was recorded at various locations in the
laboratory. Also, controlled tests of the Adaptrum transmitter were
performed at the laboratory to estimate the distances at which it might
cause interference to TV reception. Finally with input from various
interested parties, nine sites were selected for field tests of the
device's ability to sense TV signals, and two sites were chosen for
field tests of their ability to sense wireless microphones. The field
sites were selected to represent a variety of environments including
urban, suburban, rural, residential and business locations. At two of
the field test sites, anecdotal direct pick-up interference tests were
performed to assess the impact of a WSD transmitter on cable TV
reception. The following sections and the appendices provide a
tabulation of the data collected during the tests.

# White Space Prototype Devices

## Adaptrum Prototype White Space Device

Adaptrum indicates that its "Cognitive Radio (CR) Platform" is an
integrated hardware and software development system that has been
specifically designed for TV white space operation on UHF television
channels 21-51. The system is capable of various forms of TV signal
sensing including waveform/signature sensing, spectral identification,
signal power estimation, and network-level cooperative sensing. It
detects both analog and digital TV signals, but performs those functions
in two separate scans. It is not designed to detect wireless microphone
signals. The system is also capable of signal transmission in the TV
bands with flexible waveform, modulation, and signal bandwidth
construction. It incorporates transmit power control and chain
linearization to reduce adjacent channel interference. The maximum
transmitter output power specification is 100 mW (+20 dBm) over the
selected bandwidth. Figure 2-1 provides a photograph of the prototype
device/platform.

height="3.002083333333333in"}

Figure 2-1. Adaptrum Prototype WSD.

The key components of the platform are: 1) a wide-band high
dynamic-range radio frequency (RF) transceiver operating over the
frequency range 400 MHz to 1000 MHz, 2) a field-programmable gate array
(FPGA)-based hardware development board with integrated high-speed
analog-to-digital converters (ADCs) and a high-density FPGA where CR
baseband and protocol-layer functions are implemented, and 3) a
Matlab-based integrated development environment (IDE) where the CR
hardware functions are controlled using a Matlab graphical user
interface (GUI) and Matlab scripts.

The scan time associated with this prototype device was initially 37
seconds per channel (sec/ch). However, a software modification installed
to improve the detection sensitivity with respect to DTV signals with
offset pilot carriers slowed the scan time by a factor of five to 185
sec/ch. Additional information can be obtained from the Adaptrum
*ex-parte* filing in the subject rulemaking proceeding.[^12]

## Institute for Infocomm Research (I2R) Prototype White Space Device

The I2R prototype WSD operates on channels 21-51 and is capable of
sensing analog and digital TV signals and wireless microphone signals.
The device consists of: 1) a commercial TV tuner to receive television
signals and translate them to their associated intermediate frequency
(IF), 2) mixed-signal digital processing boards for performing ADC,
downconversion and filtering, 3) a laptop computer used to configure the
hardware, provide a GUI and generate reports, and 4) a fixed-length whip
receive antenna.

The (I2R) device was also able to detect wireless microphones. It
provided two scan modes -- "DTV" and "All" and two test modes -- "Lab"
and "Field". In the DTV scan mode it searched only for DTV signals and
in the "All" mode it searched only for microphones. The "Lab" test mode
was intended only for conducted bench testing and the "Field" mode was
intended only for reception of radiated signals with an antenna. Figure
2-2 presents a photograph of the I2R prototype device/platform.
Additional information can be obtained from the I2R *ex-parte* filing in
the subject rulemaking proceeding.[^13]

Figure 2-2. I2R Prototype WSD

## Microsoft Prototype White Space Device 

The Microsoft WSD platform operates on channels 21-51 and is capable of
sensing analog and digital TV signals and wireless microphone signals.
The system consists of two core system subassemblies: 1) a wide-band
spectrum scanner, a network processor and a tunable UHF half-duplex
transceiver controlled by the network processor and 2) a Windows-based
laptop computer that utilizes the Internet Explorer browser to establish
a command and control user interface via an Ethernet connection. This
device is also capable of transmitting on its operating channels.

The scanner/sensor function consists of a broadband (521-698 MHz)
computer- controlled frequency scanner and high-speed digitizer used to
incrementally scan over UHF TV channels 21-51 in 6-MHz segments. The
accumulated digitized time-domain information is then passed to the
network analyzer where a 2048-point Fast Fourier Transform (FFT) is
performed. Signal feature templates for DTV, analog TV, and wireless
microphone waveforms are sequentially compared to the resulting FFT
output to determine those channels occupied by DTV or analog TV signals.
Channels determined not to be occupied by DTV or analog TV signals are
subsequently analyzed for potential narrowband incumbent signals such as
wireless microphones. Those channels determined not to be occupied by
either DTV, analog TV, or wireless microphone signals are declared to be
available "white space" channels. User control and scanner results are
provided via the laptop computer connection.

![](media/image3.jpeg){width="4.0in" height="3.00625in"}

Figure 2-3. Microsoft Prototype WSD.

The UHF transmitter assembly consists of three sub-components: 1) an
S-Band (2.4 GHz) 802.11g OFDM modem; 2) a Half-duplex S-Band to UHF
block converter; and 3) and a network processor browser to exercise
control over frequency and power. Two external fixed-frequency bandpass
filters were provided for use in transmitter testing. A photograph of
the Microsoft WSD platform is provided in Figure 2-3. Additional
information can be obtained from the Microsoft *ex parte* filings in the
subject rulemaking proceeding.[^14]

## Motorola Prototype White Space Device

The Motorola WSD platform operates on channels 21-51 and includes
capabilities for geo-location and sensing of digital TV signals. It does
not sense analog television signals or wireless microphone signals. The
system consists of a Cognitive Radio Rack and a laptop computer host
connected via Ethernet. The rack consists of a UHF radio and two
PRO-3500 carrier boards co-located in a compact Peripheral Component
Interconnect (PCI) chassis. The cognitive engine runs on the lower
board.

This WSD implements a geo-location-based approach as its primary method
for the determination of occupied TV channels with a spectrum-sensing
capability used to refine the results of the geo-location solution and
to prioritize those channels found to be available. The geo-location
capability as tested requires the user to manually input the geographic
coordinates and relies on a downloaded version of the FCC's TV database
for a particular geographic area.

This WSD exhibited the fastest scan execution time of 0.1 sec/ch. A
photograph of the Motorola WSD is provided in Figure 2-4. More
information can be obtained from Motorola *ex parte* filings in the
subject rulemaking proceeding.[^15]

Figure 2-4. Motorola Prototype WSD.

## Philips Prototype White Space Device

The Philips WSD platform operates on channels 21-51 and is capable of
sensing analog and digital TV signals and wireless microphone signals
consists of: 1) a commercial TV tuner for tuning to a specified
television channel and translating to IF, 2) a digital signal processing
board for ADC and processing and 3) a desktop computer used to configure
the hardware, provide a GUI and store detection results.

Philips claims that the prototype WSD will scan UHF channels 21-51 and
detect ATSC (DTV), NTSC (analog TV) or wireless microphones to a level
of at least -114 dBm over a 6-MHz television channel. The channel scan
time for this device varies between 8 and 50 sec/ch due to the
sequential application of separate ATSC, NTSC and wireless microphone
detection algorithms.

Figure 2-5 presents a photograph of the Philips WSD platform. Additional
information can be obtained from Philips *ex-parte* filing in the
subject rulemaking proceeding.[^16]

# DTV Scanning/Spectrum Sensing Capability Tests

This section describes the laboratory measurements performed on each of
the prototype WSDs submitted for testing. For the sensing measurements
performed in the laboratory, a simulated or recorded signal was applied
to the antenna input of the WSD prototype utilizing a coaxial cable
connection (*i.e.*, conducted measurements). As such, the effects of the
WSD receive antenna were ignored.

Ignoring the WSD receive antenna contribution is analogous to assuming
an isotropic receive antenna (*i.e.,* a theoretical antenna having
uniform gain and directivity). An isotropic receive antenna for
ultra-high frequency (UHF) operation represents an ideal that cannot be
physically realized. Rather, the receive antenna of WSDs will likely
have low and variable (or negative gain) and thus the results reported
herein would have to be adjusted accordingly to describe practical
devices. These measurements also make no effort to quantify other
potential contributors to television signal loss such as might be
experienced from shielding/absorption effects introduced by proximate
human bodies.

The general approach to these tests was to provide a DTV input signal at
progressively lower amplitude levels until the prototype could no longer
detect it with complete (100%) reliability.

It is recognized that some of the WSD detection algorithms interpret
detection reliability as low as 50% as indicative of an occupied
channel, but the design intentions of the algorithms in other devices
were not readily apparent.

## Clean DTV Signal Measurements

The objective of the clean DTV signal measurements was to determine the
detection sensitivity of the scanning/sensing capability of the WSD
prototype devices submitted for evaluation with respect to a "clean"
(undistorted) DTV signal.

For these measurements the input was a single, simulated DTV signal
produced by a Rhode and Schwarz DTV Test Broadcast System (SFU). The
generated DTV signal was provided to the antenna input of the WSD
prototype under test via a coaxial cable. An external variable
attenuator bank was used to adjust the signal power. Block diagrams
showing the measurement equipment and related interconnections in
addition to detailed equipment information are provided in Appendix A.
The detailed procedure used to perform these measurements follows:

-   The SFU was used to produce a single, clean DTV signal that was
    provided via coaxial cable through a variable attenuator and into
    the RF input of a spectrum analyzer.

-   With the variable attenuator set to zero, the SFU power control was
    adjusted to produce an average power level of -60 dBm/6 MHz,
    referenced to the input connection of the spectrum analyzer. This
    level provides a displayed signal-to-noise ratio (S/N) of at least
    20 dB. The signal power was measured using a root-mean-square (rms)
    detector and averaged over 100 sweeps.

-   The cable from the SFU was then removed from the analyzer input and
    connected to the antenna input of the WSD prototype.

-   The SFU-generated DTV signal was further attenuated using the
    external variable attenuator bank from the -60 dBm level to a level
    slightly higher than the expected detection threshold (*e.g.*, the
    variable attenuator was typically set to provide an additional 54 dB
    attenuation so as to produce an initial input signal level of -114
    dBm)

-   Thirty (30) independent detection trials were performed with the WSD
    tuned to channel 21 (lowest channel in tuning range). The number of
    successful detections of an occupied channel was recorded.

-   If the successful detection rate over the thirty trials was 100%,
    the input signal power was reduced by increasing the variable
    attenuator by 1 dB and the procedure repeated.

-   If the successful detection rate over the thirty trials was less
    than 100%, then the input signal power was increased by decreasing
    the variable attenuator by 1 dB and the procedure repeated.

-   This iterative process was repeated until the DTV power level was
    found where the WSD prototype could no longer detect the occupying
    signal in the channel with 100% reliability.

-   Additional data points were then collected above and below this
    breakpoint.

-   The process was repeated in its entirety on two additional test
    channels, 36 and 51, representing the middle and upper channels
    within the tuning range, respectively.[^17]

The figures that follow represent the results obtained from the clean
signal DTV sensing measurements for each of the WSD prototype devices.
Two separate plots are provided for the I2R device, representing results
obtained in the two available modes of operation ("laboratory" test mode
and the "field" test mode). The field test mode utilizes separate
circuitry to suppress spurious reception.

## Recorded (Captured) DTV Signal Measurements

The objective of the recorded DTV signal measurements was to determine
the detection sensitivity of the scanning/sensing capability of the WSD
prototype devices with respect to recorded over-the-air DTV signals that
incorporate "real world" signal distortions resulting from reflections,
multi-path fading, and other factors.

The signal input for these measurements consisted of a set of twelve
recorded DTV waveforms ("captures") selected by the IEEE 802.22
subcommittee.[^18] Detailed information, including frequency domain and
temporal representations of each of these twelve waveforms, is provided
in Appendix B of this report.

A Wavetech Services WS-2100 RF player^®^ was used to play back the
captures on the desired RF channel and to provide them to the antenna
input of each of the WSD prototypes via coaxial cable. Two external
variable attenuator banks were utilized to adjust the power level of the
input signal. A 75-50 Ω transformer was utilized at the Wavetech player
output to match system impedance.

Although different algorithms are utilized among the prototype devices
to detect the presence of a DTV signal, they all appear to share a
similarity in that they all sample the spectrum in proximity of an
anticipated DTV pilot signal. However, the amount of time dedicated to
sampling and signal processing differs significantly among the prototype
devices. Since there are significant instantaneous temporal variations
in many of the RF captures over their 25-second playback period (see
Appendix B), the resulting detection decisions can also vary depending
on when the sampling actually occurs. Efforts were made to minimize this
variable (*e.g*., the waveform playback was restarted for each
independent trial); however its effect is evident in the results
obtained from some of the prototype devices. Another method for reducing
this variability is to increase the number of trials beyond the stated
number of thirty. For some of the devices, the additional time required
to execute more than thirty trials was excessive and was thus deemed
impractical. However, for others (*e.g*., the Motorola WSD), it was
practical to perform additional trials. Therefore, for this device, in
addition to performing the measurement over thirty independent trials, a
second measurement was also performed utilizing one thousand independent
trials. The results of both measurements are provided herein.

After the laboratory measurements were completed but before the field
trials commenced, the prototype manufacturers were offered an
opportunity to make minor adjustments to their devices based on the
laboratory results. For example, one issue observed by the manufacturer
of the Adaptrum prototype was difficulty in detecting a DTV signal
having a frequency offset pilot tone. As a result, Adaptrum utilized
this opportunity to improve this with a software modification.[^19] A
second set of data is presented for the Adaptrum device showing the
effect of this modification.

Block diagrams showing the measurement equipment and related
interconnections in addition to detailed equipment information are
provided in Appendix A. The measurement procedure was as follows:

-   A Wavetech Services WS-2100 RF player^®^ was used to play back each
    of twelve recorded DTV signals and provide the RF output via coaxial
    cable through an external variable attenuator bank and into the RF
    input of a spectrum analyzer.

-   With the external variable attenuators set to zero, the average
    output signal power in the channel bandwidth was measured using the
    spectrum analyzer (over 100-sweeps utilizing an rms detector).

-   The coaxial cable was then removed from the RF input of the analyzer
    and connected to the receive antenna input of the prototype device.

-   The signal was further attenuated using the variable attenuator bank
    to achieve a power level near the threshold level recorded in
    Section 3.1.

-   Thirty (30) independent trials were performed and the number of
    successful detections recorded.[^20] Since the data from the Section
    3.1 indicated relative consistency over the three channels examined,
    these tests were performed only on a single channel (typically
    channel 36, mid-channel in the WSD tuning range).[^21]

-   If the successful detection rate over the thirty scans was 100%,
    then the input signal power was reduced by increasing the
    attenuation by 1 dB and the procedure repeated.

-   If the successful detection rate over the thirty scans was less than
    100%, then the input signal power was increased by reducing the
    attenuation by 1 dB and the procedure repeated.

-   The process was repeated until the DTV power level was found where
    the WSD prototype could no longer detect the signal in the channel
    with 100% reliability.

-   Additional data points were then collected above and below this
    breakpoint.

The results of these measurements are provided in the figures that
follow.

## Two-Signal (Adjacent Channel Interference) Measurements

The objective of the two-signal adjacent-channel interference
measurements was to assess the potential for degradation to the DTV
signal detection capability when another DTV signal is present on an
adjacent channel. Because of equipment limitations, these measurements
were limited to assessing the effect of one adjacent channel at a time
(*i.e.*, two-signals, one on the detection channel and one on an
adjacent channel). The effects of DTV signals on both first- and
second-adjacent channels were tested.

Detection threshold measurements were made in a manner similar to that
described in Section 3.1, but included one additional DTV signal placed
sequentially on the first (N±1) and then second (N±2) adjacent channels
relative to the detection channel. Detection threshold measurements were
performed with the adjacent-channel signal power set to the -28 dBm
(high), -53 dBm (moderate) and -68 dBm (low) levels. It should be noted
that DTV signal levels in "real world" environments can exceed -28 dBm
and actual examples of this were observed in the field test component of
this effort (see Section 5.2).

For these measurements, the R&S SFU was used to generate the
adjacent-channel DTV signal. The Wavetech player was used to play back a
"clean" DTV signal (Zone Plate test signal) in the detection channel.
The power level of the adjacent channel DTV signal was set using the
SFU's internal power controls and verified with a spectrum analyzer. The
power level of the detection-channel signal was set utilizing a bank of
external variable attenuators and verified with a spectrum analyzer.

The SFU provides a good representation of a DTV signal within the 6 MHz
TV channel passband but it does not precisely match the out-of-band
characteristics of operating DTV stations (*i.e.,* the "DTV Mask" for
full service stations). Therefore, in order to preclude the possibility
of excessive signal leakage ("splatter") from the adjacent channel into
the detection channel, the DTV signal was filtered through a 7-pole RF
bandpass filter in order to more accurately simulate the out-of-band
characteristics of a "real world" DTV broadcast signal.

The filter employed was a Micro Communications, Inc. fixed-tuned
Interdigital Bandpass (IDBP) filter.[^22] Passing the SFU-generated DTV
waveform through this filter provides out-of-band characteristics that
adhere to the DTV emissions mask (see Appendix A).[^23] However, since
the filter is fixed-tuned to channel 29, the adjacent-channel signal had
to be maintained on channel 29 while the detection channel was varied to
represent the N±1 and N±2 relationships with respect to the detection
channel. For example, in order to examine the effect of an N+1 adjacent
channel interaction, the SFU DTV signal (representing the
adjacent-channel signal) was generated on channel 29 and the Wavetech
DTV signal (representing the detection-channel signal) was generated on
channel 28. Likewise, the N-1 adjacent channel scenario was simulated by
transmitting the detection signal on channel 30 and the N+2 and N-2
scenarios were simulated by transmitting the detection signals on
channels 27 and 31, respectively, while the adjacent-channel DTV signal
remained on channel 29.

During the course of these measurements, the Microsoft prototype sample
device began to malfunction and eventually ceased to operate,
necessitating the abandonment of further measurements utilizing this
device.

As mentioned above, before the field trials were initiated, the
prototype manufacturers were offered an opportunity to make minor
adjustments to modify their devices based on the bench-test results. One
issue observed by the manufacturer of the Motorola prototype was
degradation to the detection capability in the presence of an
adjacent-channel DTV signal (particularly one at moderate and higher
power levels). Motorola utilized this opportunity to add an automatic
gain control (AGC) circuit to the device.[^24] This necessitated that a
second set of laboratory data be collected from this prototype to
demonstrate and verify the effect of the modification.

Block diagrams showing the measurement equipment and related
interconnections in addition to detailed equipment information are
provided in Appendix A.

The measurement procedure was as follows:

-   The SFU was used to generate a DTV waveform on channel 29 that was
    delivered via coaxial cable through a fixed-tuned bandpass filter to
    provide the adjacent-channel signal. The Wavetech player was used to
    playback another DTV waveform on the pertinent detection channel.
    The detection-channel signal was provided via coaxial cable through
    a bank of external variable attenuators and combined with the
    adjacent channel signal. The combined signals were split with one
    output connected with coaxial cable to the antenna input of the WSD
    prototype device and the other output connected with identical
    coaxial to a spectrum analyzer. A block diagram of this set-up is
    provided in Appendix A.

-   The SFU-generated adjacent-channel signal was set to produce a
    signal with amplitude of -28 dBm at the spectrum analyzer input. For
    subsequent measurements, this same procedure was used to set the
    adjacent-channel signal power to -53 dBm (representing a moderate
    level) and -68 dBm (representing a low level), respectively.

-   The Wavetech RF player was set-up to provide the detection signal on
    channel 28, simulating an N+1 adjacent-channel scenario (*i.e.,*
    channel 28 detection channel with a second DTV signal in the upper
    adjacent channel 29). In subsequent measurements, the output channel
    of the Wavetech player was set to channel 30 (N-1), channel 27
    (N+2), and channel 31 (N-2) to represent the remaining three
    adjacent-channel scenarios under examination.

-   With the external variable attenuator set to zero, the power in the
    detection channel was measured with the spectrum analyzer. Using
    this measurement as a baseline, the variable attenuator banks were
    adjusted to reduce the signal power in the detection channel to a
    level near the previously observed detection threshold.

-   Thirty (30) independent trials of the WSD detector were performed in
    the detection channel and the number of successful detections was
    recorded.

-   If the successful detection rate over the thirty independent trials
    was 100%, then the input signal power was reduced (by increasing the
    signal attenuation) and the procedure repeated.

-   If the successful detection rate over the thirty trials was less
    than 100%, then the input signal power was increased (by decreasing
    the signal attenuation) and the procedure repeated.

-   The process was repeated until the DTV power level was found where
    the WSD prototype could no longer detect the signal with 100%
    reliability.

-   Additional data points were collected at levels above and below this
    breakpoint.

The data resulting from these measurements are presented below in Table
3-1. Only the final signal level where 100% correct detection was
observed is reported in this table.

## Transmitter Measurements

### Conducted Measurement 

The objective of the conducted transmitter measurements was to examine
the emitted spectral characteristics of those WSD prototype devices
having a transmit function. Two of the originally-provided WSD
prototypes include active transmitters, the Adaptrum and Microsoft
devices. Prior to these measurements, the Microsoft device
malfunctioned. However, the spectral characteristics associated with the
Microsoft WSD transmitter are expected to be unchanged from those
measured and reported in the Phase I measurements.[^25]

The Adaptrum WSD was used with an external wide-band amplifier to boost
the power applied to the transmit antenna. The emission spectrum was
measured by connecting the transmitter/amplifier output through a 30 dB
attenuator to a spectrum analyzer. Figure 3-13 presents the resulting
spectral plot.

> ![](media/image19.wmf){width="5.776388888888889in"
> height="4.657638888888889in"}

Figure 3-19. Adaptrum Transmitter Emission Spectrum.

The following information can be determined from this data:

-   The bandwidth of the transmitted signal is approximately 4.5 MHz.

-   The out-of-band (channel) emission (OOBE) suppression is slightly
    more than 86.5 dB (60 dB + 10 log(4.5 MHz/10 kHz)) relative to the
    total power in the carrier.

-   The output power is shown as -36 dBm as measured in a 10-kHz
    resolution bandwidth. This converts to a level of -9.5 dBm (-36 +
    10log (4.5 MHz/10 kHz)) in the 4.5 MHz emission bandwidth. A 30-dB
    external attenuator was utilized to protect the spectrum analyzer
    from overload and the coaxial cable loss was measured at 1.2 dB.
    Therefore, the final conducted output power from the WSD is (-9.5 +
    30 + 1.2) = 21.7 dBm or approximately 150 milliwatts.

### Radiated Measurement

Measurements were made to derive the equivalent isotropically radiated
power (EIRP) based on measurements of the radiated power of the
transmitter in the Adaptrum WSD prototype. In order to determine the
EIRP of this device's transmitter, a set of radiated measurements were
performed utilizing the laboratory's semi-anechoic chamber. For these
measurements, the WSD was placed atop a wooden test bench that is
mounted on a turntable and activated in the transmit mode of operation.
A calibrated laboratory-grade receive antenna was affixed to a
variable-height mast at a separation distance of 3-meters relative to
the transmit antenna. The WSD transmit antenna and the calibrated
receive antenna were varied in relative orientation (*e.g*., with
respect to polarization, height and angular position) until a maximum
signal level was obtained on a spectrum analyzer. This measurement
process was repeated on three distinct frequencies representing the
lower, middle and upper tuning range of the transmitter. The maximum
received signal level was recorded at each frequency.

The maximum EIRP of the transmitter can be determined from the measured
maximum received power by applying the following equation:

> EIRP = P~R~ -- G~R~ + L~C~ + L~P~ (1)
>
> where;
>
> P~R~ = received power measured with the spectrum analyzer, in dBm,
>
> G~R~ = receive antenna gain, in dBi,
>
> L~C~ = signal attenuation in coaxial connecting cable, in dB,
>
> L~P~ = free space propagation path loss, in dB.

The receive antenna gain was determined from manufacturer-provided
calibration data, the signal attenuation in the connecting coaxial cable
was measured and the free-space propagation path loss[^26] was
calculated for each measurement frequency. The parameters used in
Equation (1) along with the results are provided in Table 3-2 below.

## Miscellaneous Laboratory Measurements

This section describes some miscellaneous measurements performed on the
WSDs that were not a part of the original test plan. These measurements
were typically undertaken to help explain unusual and/or unexpected
observations.

In preparation for the field trials, the detection capabilities of the
prototype devices were first exercised in the over-the-air environment
at the laboratory facility (sensing the real world environment, not
laboratory test signals). Several of the devices indicated that all (or
most) channels were occupied even though it was known that unoccupied
(available) channels existed at the laboratory.

These miscellaneous measurements represent an attempt to investigate
working hypotheses regarding these unanticipated observations. Since
these measurements were solely exploratory, they were not necessarily
performed consistently over the set of all prototype devices. In fact,
because of the late submission of the I2R device, none of these
measurements were performed with it. In other cases, only a partial
suite was performed, particularly if preliminary results did not raise
concerns.

The first of these measurements consisted of exercising the detection
capability of the WSD device using its associated antenna at locations
within the laboratory (indoors), in the laboratory's parking lot
(outdoors), and inside of the laboratory's semi-anechoic chamber. When
some of the devices indicated significant channel occupancy inside the
anechoic chamber (where all environmental UHF signals are significantly
attenuated), a set of measurements were performed to examine possible
explanations. Radiated measurements were performed to determine the
spurious energy emitted by the prototypes under the assumption that at
sufficient intensity they may trigger false detections. No effort was
made to isolate the source of the spurious emissions among the
individual system components.

The results of these measurements are presented in Appendix H. The
tables provided in Section H.1 provide the results obtained from
exercising the WSD sensing/detection capability within the laboratory.
Section H.2 presents spectral plots representing the data collected from
the radiated spurious emissions measurements. These tables and plots
show that many of the prototype platforms generate emissions internally
at levels that create a potential for degrading a device's detection
capability (in the form of high missed detection and/or false alarm
rates).

The clean signal results indicate that the measured detection threshold
ranges between -116 and -126 dBm (ignoring the I2R results in field test
mode) over the complete set of prototype devices. The results also
indicate that the detection threshold is relatively consistent over the
tuning range of the device.

The measured detection thresholds with respect to the twelve DTV
waveform captures range between -106 and -128 dBm over the total set of
prototype devices. Variability observed in the results of the waveform
capture tests when compared with the results of the clean waveform tests
is explained partly by temporal amplitude variations in the recorded
waveform.

The adjacent-channel sensitivity measurements indicate that
moderate-to-strong DTV signals occupying channels adjacent to the
detection channel can significantly degrade detection capability,
thereby affecting the ability of a device to reliably detect DTV
signals.

Transmitter measurements on the one WSD with transmit capability
demonstrated a clean output spectra with good out-of-band emission
(OOBE) suppression. The maximum EIRP of the device was determined to
nominally be +22 dBm (\~150 mW) over the tuning range and the OOBE
suppression was found to be at least -86.5 dB.

The miscellaneous measurements showed that many of the prototype
platforms generate emissions internally, at levels that create a
potential for degrading the devices' detection capabilities (in the form
of high missed detection and/or false alarm rates).

# WSD Transmitter Interference Tests and Demonstrations

This section describes transmitter interference tests performed as a
part of the Phase II measurement effort. These tests are considered
anecdotal for a number of reasons. For example, the use of over-the-air
signals implies that little control could be exercised upon significant
test variables. In addition, since the tests were performed at a limited
number of locations and at particular times of day, variations in signal
level occurred which could not be characterized. Also, since the
Adaptrum WSD prototype was the only available working device with a
transmitter, the interference effects to DTV reception were examined for
only the waveform of this particular device, which may or may not be
representative of a final TV white space product.

These tests all utilized the Adaptrum WSD transmitter to radiate an
undesired signal while the potential victim receive system was monitored
visually for interference. Attempts were made to operate the victim
receiver in a minimum desired signal condition to represent a worst-case
interference scenario.

Section 4.1 describes a test performed to assess potential
adjacent-channel and co-channel interference interactions when a
proximate DTV receive system is tuned to a station near the recognized
threshold of visibility (TOV) of -84 dBm. This test was performed within
the FCC laboratory facility.

Section 4.2 describes tests performed at two of the residential field
trial sites to assess the potential for interference to the reception of
cable television programming via the direct pick-up of an undesired
WSD-transmitted signal either by the coaxial cable/connections, the
television tuner and/or a set-top converter box. In these tests, the
precise interference entry point was not identified.

## Channel Interference Potential to DTV 

The objective of this test was to examine interference distances between
the prototype WSD transmitter and a typical consumer-installed DTV
receiving system, with WSD transmissions either on the same or on an
adjacent channel relative to a weak-signal DTV signal. The co-channel
scenario is one that should be avoided by the WSD channel detection
scheme, but is investigated as a part of this effort in order to provide
an estimate of the interference distance in the case where the detection
scheme fails to identify a weak-signal occupied channel.

### Undesired Signal (U) Transmission System 

The undesired signal was produced by the Adaptrum transmitter coupled
with an external 21 dB gain wideband amplifier. The WSD is capable of
transmitting an OFDM signal with a signal bandwidth adjustable from 0.5
to 18 MHz. A vertically-polarized planar bi-conical transmit antenna at
a height of 2 meters (6.6 feet) above ground level (AGL) was used to
radiate the signal generated by the transmitter. The EIRP of the WSD
prototype transmitter was measured in the semi-anechoic chamber and
determined to nominally be +22 dBm (\~150 mW). See Section 3.4 for
details. Figure 4-1 presents a photograph of the WSD signal transmission
system on the laboratory grounds.

### Desired Signal (D) Receive System 

The receive system used in these tests consisted of a consumer-grade
horizontally-polarized television antenna (Radio Shack VU-90XR) mounted
at a height of 9.3 meters (30.5 feet) on the rotor-driven extendable
mast of an FCC measurement truck and connected via coaxial cable
sequentially to 1) an Agilent E7405A spectrum analyzer with internal
pre-amplifier and 2) a commercial set-top box with a late-generation DTV
tuner (Magnavox) feeding a consumer DTV receiver (JVC). See Figures 4-2
and 4-3 for photographs of the desired signal receive and measurement
system.

### Test Methodology

The following test procedure was used for the transmitter field tests:

-   The DTV receive antenna was mounted on the extendable mast of the
    FCC measurement truck and elevated to 9.3 meters (30.5 feet) above
    ground level (AGL) to simulate a consumer-installed roof-top mounted
    antenna. The truck was parked on one end of the FCC laboratory
    property.

-   A 75-50 Ω transformer was used to connect the antenna through the
    antenna feed (coaxial cable) to a spectrum analyzer.

-   The antenna was rotated and the spectrum analyzer used to examine
    the received power levels associated with all available DTV
    channels.

-   Power measurements were compared to determine the weakest receivable
    signal. This signal was used as the desired signal in these tests.
    By this method, channel 30 (WNVT-DT in Goldvein, VA, approximately
    50-miles distant) was selected as the desired channel for this test.
    The measured channel power of WNVT-DT was found to vary between -75
    and -77 dBm at the test location.

-   The antenna feed was then switched from the spectrum analyzer to the
    set-top box and the signal content displayed on the DTV receiver.

-   The signal was observed to produce a stable picture without obvious
    artifacts.

-   A step attenuator was inserted into the signal path and the desired
    signal was attenuated in 1 dB steps until the picture was lost. By
    this method it was determined that a 5-6 dB margin existed between
    the received and threshold signal levels. This confirmed the TOV of
    the receiver to be within the range -80 to -83 dBm.

-   The Adaptrum WSD transmit system (transmitter and supplied antenna)
    was initially placed at a distance of 12.2 meters (40 feet) from the
    base of the receive antenna mast along the same radial as the
    receive antenna boresight and oriented to maximize
    mainbeam-to-mainbeam coupling (not considering cross-polarization
    losses). The transmitter was tuned to each of the immediately
    adjacent channels (29 and 31) and the OFDM signal was transmitted at
    full power in a 4.5 MHz bandwidth. No interference was observed to
    the set-top box/DTV receiver while receiving WNVT programming on
    channel 30.

-   The distance was decremented in 3.1 meters (10 feet) steps and the
    adjacent-channel tests repeated. No adjacent-channel interference
    was observed on the DTV at any distance; however, alternative test
    configurations were not explored.

-   This test was repeated with a transmit bandwidth of 6 MHz. Again, no
    interference could be produced with the WSD transmitter tuned to
    either of the immediately adjacent channels.

-   The WSD transmitter was then tuned to channel 30 (co-channel) with
    an emission bandwidth of 4.5 MHz.

-   The transmit antenna was initially placed at a distance of 45.7
    meters (150 feet) from the base of the receive antenna along the
    same radial as before.

-   The transmitter was activated at full power. Interference was
    immediately observed in the form of complete loss of the television
    picture.

-   The transmit channel was changed to 31 in order to isolate from the
    desired signal and the power through the receiver chain measured. It
    was determined that at this distance, the undesired power level was
    28 dB above the desired power (D/U = -28 dB) which suggested that
    considerable additional distance would likely have to be realized to
    mitigate the interference (*i.e.*, to achieve a D/U of 15 dB
    requires 43 dB additional attenuation of the undesired signal).

-   In order to achieve as much attenuation as possible from distance
    separation (while still maintaining a line-of-sight propagation
    path), the transmitter and receiver systems were separated as far as
    practical within in the confines of the laboratory property.

-   The maximum distance that could be practically obtained between the
    transmitter system and the receiver system while staying within the
    receive antenna mainbeam was 360 meters (1180 feet). The transmitter
    was again activated at full power within a 4.5-MHz bandwidth and
    co-tuned with the desired signal (on channel 30). Interference was
    once again observed as a complete loss of picture. The desired
    signal level was measured on channel 30 and determined to be -76.9
    dBm and the undesired signal level was measured on channel 31 and
    determined to be -77.4 dBm (D/U = 0.5 dB)

[]{.mark}

-   Since no greater distance separation could be practically realized,
    a step attenuator was placed between the transmitter amplifier and
    antenna and used to further attenuate the undesired signal until the
    interference was eliminated. It was found that an additional 15 dB
    of attenuation was required to resolve the interference (D/U = 15.5
    dB). The results of this test are summarized in Table 4-1.

-   The test was repeated with the WSD transmitter located to the side
    and behind the DTV receive antenna, in order to observe the
    variation in interference level as the WSD was moved off boresight
    of the receive antenna (away from the axis of symmetry of the
    mainbeam). The resulting data are summarized in Table 4-2. The
    approximate locations associated with the side- and back-lobe tests
    are shown in the aerial image provided as Figure 4-4.

## Direct Pick-Up Interference to Cable Service 

Anecdotal checks for direct pick-up interference to cable service were
performed at the two residential test sites with cable television
subscriptions (the third residential site did not subscribe to cable
service). The intent was to observe the susceptibility of cable TV
reception to interference caused by the direct pick-up of emissions from
a WSD prototype transmitter. This interference mechanism has been
previously examined and documented by the FCC laboratory.[^27]

Consumer cable service networks in the United States typically utilize
quadrature-amplitude-modulated (QAM) signals to provide digital
television programming. This requires a dedicated QAM demodulator,
distinct from that used to demodulate ATSC 8-VSB broadcast signals. Many
DTV receivers include both QAM and ATSC 8-VSB demodulators to permit
reception of digital cable signals without the need for a separate
set-top box. A DTV equipped with a QAM tuner can thus receive
unencrypted digital cable TV programming (and also encrypted cable
programming if equipped with an active CableCard).

The frequency plan of cable channels differ from the frequency plan of
broadcast television channels. Cable channels are offset in frequency
relative to over-the-air (broadcast) channel allocations.[^28] Cable
channels also use different numeric designations and include channels on
frequencies not used by broadcast television. At each test site, it was
necessary to find an analog and an unencrypted (clear QAM) digital cable
channel whose frequencies overlapped the spectrum of a broadcast channel
within the tuning range of the Adaptrum prototype WSD transmitter.

### Field Test Site 3 (Residential)

Cable channel 73, (519.0 ± 3.0 MHz) was identified as an analog cable
channel available at this test site. The Adaptrum WSD prototype can tune
its transmitter to channel 21 (515.0 ± 3.0 MHz), which overlaps cable
channel 73. Therefore, this channel combination was used to observe the
interference potential to analog CATV reception at test site 3.

First, a spectrum analyzer was used to measure the channel power at the
cable service outlet, utilizing a 75-50Ω transformer. The measured
channel power from the cable TV outlet at site 3 was -7 dBmV. The
applicable standard states that the carrier level at the "input
terminals of the first device located on the subscriber premises" should
be -12 to +15 dBmV.[^29] A step attenuator was inserted into the cable
signal path and used to reduce the power on channel 73 at the DTV
"cable" input to -11 dBmV (1 dB above the minimum specified level).

The cable service was then attached to the "cable" input of a digital
widescreen television, bypassing the existing cable routing (including a
distribution amplifier, splitters, various cables, and a set-top
converter box). Figure 4-5 presents a line-diagram of the cable receive
system at test site 3. The DTV receiver was tuned to cable channel 73
and a good quality analog picture was observed.

Figure 4-5. Line Diagram of Cable TV Receive System at Test Site #3.

**Interference to Analog Cable Service.** The Adaptrum antenna was
placed on a tripod at a height of approximately 1.5 meters and
approximately 1 meter horizontally distant from the TV. The antenna was
connected to the WSD transmitter output port via coaxial cable through a
step attenuator and mounted in its normal polarization (vertical). The
prototype transmitter was tuned to channel 21 and activated at full
power (no external attenuation). The picture quality on the cable
channel was observed to be significantly degraded. The Adaptrum
prototype provides for a variable transmit bandwidth. Using that
feature, the transmit bandwidth was reset from 4.5 MHz to 6.0 MHz and
the demonstration repeated. Interference to the TV became noticeably
worse.

The cable service signal path was changed to include the existing cable
routing (including the distribution amplifier, etc., but without the
converter box) and the test was repeated. Again, interference was
observed on the TV receiver and was also noted on an analog TV in an
adjacent room, which was tuned to channel 73, in the form of a complete
loss of picture.

The step attenuator in the transmitter signal path was used to decrease
the transmitted signal level from the maximum power (+22 dBm EIRP based
on data presented in Section 3.4) in 1 dB steps while observing the DTV
for interference. With 15 dB of signal attenuation (7 dBm EIRP), the
interference was barely perceptible (on either TV).

**Interference to Digital Cable Service.** Next, an attempt was made to
observe the interference potential from the WSD transmitter to a digital
cable (QAM) channel. Cable channel 77 (543.0 ± 3.0 MHz) was identified
as a clear QAM Cable TV channel available at this test site. The
Adaptrum WSD prototype transmitter can tune to broadcast TV channel 26
(545.0 ± 3.0 MHz), which overlaps CATV channel 77. Therefore, this
channel combination was used in the demonstration.

The digital widescreen TV was tuned to channel 77 but could not
demodulate the signal. Thus, a demonstration of the interference
potential to the TV's QAM tuner could not be performed at this site.

The cable converter (set-top) box was inserted into the signal path and
connected to the DTV's tuner input. The set-top box was tuned to virtual
channel 220 (cable channel 77) and a good quality digital picture was
observed. The Adaptrum transmitter was tuned to channel 26 and activated
at full power (no external attenuation). Interference was immediately
observed in the form of a complete loss of picture.

The variable attenuator was incrementally increased to reduce the
radiated power in 1 dB steps. At a reduction of 18 dB (4 dBm EIRP) the
picture reappeared. The attenuation in the cable signal path was removed
and the test repeated. Picture loss was again observed at a transmit
attenuation setting of 12 dB (10 dBm EIRP).

Finally, all of the existing routing from the cable service wall outlet
to the converter box (including amplifier, splitters and cables) was
removed and replaced with a laboratory-grade patch connecting the wall
outlet and the converter box input. The Adaptrum transmitter was reset
to its maximum power (all external attenuation removed) and turned on.
No interference was observed until the transmit antenna was moved very
close to the converter box (within 0.3 meters).

**[Tentative Conclusions at Test Site #3]{.underline}**

> • The residence's wiring, preamps, and television receivers were
> susceptible to direct pick-up (DPU) interference in analog mode.
>
> • The cable converter set-top box operating in QAM mode was almost
> immune to interference from the WSD transmitter (this set-top box was
> not tested in the analog mode).

### Field Test Site 6 (Residential) 

A line diagram of the cable service receive system at test site #6 is
presented as Figure 4-6. Digital cable signals were processed by the
digital set top box; analog cable signals passed through the digital set
top box and were processed by the tuner/demodulator set top box.

Figure 4-6. Line Diagram of Cable TV Receive System at Test Site #6.

The peak visual carrier level on cable channel 72 (511.25 MHz)[^30] from
the connector at the wall was measured at +1 dBmV.[^31] No additional
attenuation was used for the tests at this site.

**Interference to Analog Cable Service.** The Adaptrum transmitter was
set to operate with a 6 MHz transmit bandwidth on TV channel 21
(512--518) MHz, and its antenna was located about two meters from the
analog cable converter box (which fed via HDMI a video monitor). The
picture showed perceptible interference (TASO Grade 3) when the
transmitter was energized. The antenna was then relocated about one foot
from the set top box and the picture degraded further and showed
definitely objectionable interference (TASO Grade 5).

With the WSD antenna located about two meters from the analog cable
converter box the transmit power output from the WSD was reduced in one
decibel steps until the interference became barely visible on the video
monitor. This threshold of visibility was found at +13 dBm (9 dB below
full transmitter output power).

**Interference to Digital Cable Service.** The Adaptrum transmitter was
set to operate on TV Channel 30 (566--572 MHz). The cable signal path
ran from the wall outlet through a splitter to a digital cable converter
set top box.[^32] Cable channel 81 (564--570 MHz) was used for the
tests; the measured channel power in 6 MHz was -7 dBmV.[^33] The 256 QAM
cable channel provided six program streams, corresponding to virtual
channels 2, 4, 5, 6, 9, and 12. The set-top box was tuned to (virtual)
channel 2 for the tests.

The WSD transmitter's antenna was located about four meters from the
set-top box. When the transmitter was energized at +22 dBm, the picture
experienced occasional blocking, indicating "weak" interference. When
the transmitter antenna was relocated to a position two meters from the
set-top box, the blocking became frequent, and at a distance of one
meter, the picture froze and then disappeared. The same severity of
interference was observed at each distance with the transmitter set to
either 4.5 or 6 MHz transmit bandwidth.

With the WSD transmitter's antenna at a distance of two meters from the
set-top box, 3 dB of attenuation was introduced between the WSD
transmitter and its antenna, and the interference ceased. This
represents a transmitter power output of +19 dBm.

The additional 3 dB of signal attenuation was removed and the WSD
transmit antenna was maintained at a distance of 2 meters from the
set-top box, and rotated from vertical to horizontal. The severity of
the interference increased when the antenna was rotated. Additional
attenuation of 11 dB was required to eliminate the interference,
representing a power output of +11 dBm.

**[Tentative Conclusions from Location #6 Tests]{.underline}**

> • The residence's cable receiving system was susceptible to direct
> pick-up (DPU) interference in analog mode when the WSD transmit
> antenna was within two meters of the RF components.
>
> • The residence's digital cable set-top box was susceptible to
> interference from the WSD in QAM mode (analog mode not tested) at a
> distance of about two meters.
>
> • The digital set-top box was more susceptible to interference from
> the WSD transmitter when the transmit antenna was horizontally
> polarized.

## Summary of Results

The results of the tests described in Section 4.1 demonstrate that a DTV
receive system tuned to a weak DTV channel can experience interference
at significant separation distances (data extrapolation indicates to up
to 1.2 km) from the WSD transmitter when it is radiating a signal at
\~150 mW EIRP.

With the transmitter operating at full power on a channel adjacent to a
weak channel being received by the DTV receiver system, interference was
not observed in a simulated rooftop-mounted receive antenna scenario.

These tests served to informally validate currently accepted D/U
thresholds for co-channel interference (15 dB).

Direct pick-up interference to cable television reception was
demonstrated at transmit power levels consistent with those reported in
previous FCC measurement efforts. The interference appears to be
dependent on the configuration of the cable installation and whether or
not a set-top box was used and if so, the susceptibility of the box to
signal ingress.

# TV-Sensing (Channel Occupancy) Field Tests

This section describes the field measurement component of the Phase II
measurement effort and provides a summary of the data collected. This
component involved field trials performed with each of the WSD
prototypes in an effort to assess their ability to detect incumbent
television stations in "real world" environments. Measurements of
over-the-air TV signals were also performed at each site to determine
the occupancy of each television channel over the range 21-51.

Four of the originally submitted WSD prototypes were used for these
tests. As previously discussed, prior to the commencement of the field
tests, Adaptrum modified its device to improve the detection of DTV
signals with frequency offset pilot carriers.[^34] Unfortunately, this
software patch resulted in the device taking considerably longer to
perform a full 31-channel scan.[^35] This limited the number of trials
that could be practically performed with this device at each test
location. Motorola also modified its device prior to the field tests to
mitigate overload problems resulting from strong adjacent channel
signals.[^36]

Nine field sites were selected for these tests, representing a mix of
urban, suburban and rural locales. The sites included three private
residences, an office building and five outdoor locations. Table 5-1
lists these nine test sites. More information is provided on a
site-by-site basis in the following subsections.

Trials of the detection capabilities of each of the WSD prototypes were
performed from two distinct locations at each test site (the Adaptrum
device was often limited to one full-scan trial due to time
limitations). The rationale for performing trials from two separate
locations at each site was to attempt to avoid the possibility of
testing in a signal null zone. This practice also provided an
opportunity to examine the consistency in the results between proximate
locations. Except for the Adaptrum WSD, two trials were performed at
each of two locations, for a total of four separate trials at each site.

The WSDs were generally operated separately and sequentially in order to
prevent spurious energy generated by one prototype from affecting the
results of another (exceptions were at test sites 5 and 8, where an
adequate distance between the WSDs could be achieved). Although only
four WSDs were tested, the Motorola prototype was tested in two
configurations at each site ("normal or geolocation" and "test or
sensing" modes), and at several sites the Philips prototype was also
tested in a second configuration (with external attenuation added
between the antenna and the receiver input).

At each test site, measurements were performed to determine the
occupancy of each of the channels in the 21-51 range. These measurements
involved using the FCC truck, equipped with a pneumatic mast that was
used to extend a consumer television receive antenna to a height
(relative to ground level) of approximately 9.1 meters (30 feet) in an
effort to simulate a typical rooftop antenna installation. The antenna
was connected first to a spectrum analyzer via coaxial cable and rotated
to optimize reception on each channel. A spectrum analyzer was used to
identify the signal type and to measure the associated signal power
level. For digital TV (ATSC) signals, the power level was measured as
the integrated power over the 6-MHz channel. For analog TV (NTSC)
signals, the power level was measured in terms of the peak-of-sync power
of the visual carrier. After completing these measurements, the antenna
lead was connected to an appropriate receiver to determine whether a
"viewable" picture could be displayed. For those channels occupied by
DTV signals, a digital-to-analog set-top box was used as the tuner,
paired with the display portion of a digital television receiver. For
channels with analog signals, the antenna lead was connected directly to
the TV receiver. Additional details regarding these on-site measurements
are presented in Appendix C.

Several anecdotal interference tests were also performed as a part of
these field measurements. As discussed above, at sites 3 and 6, tests
were performed to aid in assessing the potential for direct pick-up
interference to cable television reception (see Section 4.2).
Additionally, anecdotal tests of the wireless microphone detection
capability implemented in two of the prototype devices (Philips and I2R)
were performed at test sites 3 and 5. This data is described elsewhere
in this report (see Section 6).

The following subsections describe the test sites in greater detail and
present the information and data collected at each. For each test site,
a table is presented that summarizes information associated with each
channel in the 21-51 range (excluding channel 37). This table provides
six columns of data obtained from the FCC database, augmented with a
column of data obtained from on-site observations. The data under each
column header are as follows:

-   **CH** -- lists each channel from 21-51, excluding channel 37 (which
    is reserved for Radio Astronomy and in-hospital wireless medical
    telemetry operations).

-   **Station Call Sign** -- lists the station identifier (call sign)
    for each TV station (transmitter location) within a 100-km radius of
    the test site. The 100-km radius was chosen because it is larger
    than the service areas of most analog and digital TV broadcast
    stations.

-   **Station Location** -- lists the community associated with each
    licensed station.

-   **Signal Type** -- identifies whether the channel is anticipated to
    be occupied with an analog or digital television broadcast signal
    based on information extracted from the FCC consolidated database
    system (CDBS).

-   **Separation Distance** -- provides the distance (in kilometers)
    between the station's broadcast antenna site and the test site
    location.

-   **Within Service Contour** -- identifies whether or not the test
    site is located within the calculated service contour of the
    associated station.

-   **Viewable** -- identifies whether or not a television signal could
    be demodulated and viewed with the test receiver set-up utilized in
    this effort.[^37] In declaring an NTSC channel as viewable, no
    consideration was given to received picture quality.

Subsequent tables are presented for each test site that provides the raw
data from the field trials for each WSD prototype. The unique column
headings used in tables are described as follows:

-   **Measured Signal Type** -- identifies whether the actual measured
    signal on each channel was digital or analog. In general, this data
    was consistent with the anticipated signal type; however exceptions
    were observed. These exceptions can be explained. Often, the
    anticipated signal was associated with a low-power station located
    some distance from the test site. In such cases, it is plausible
    that a full-power station located beyond 100-km will overpower the
    low-power station. Additionally, because of differences in the
    methodology for measuring and expressing analog and digital signal
    levels, it's possible to measure NTSC signals at a lower receive
    carrier level than ATSC signals. Thus, it's often possible to
    measure an analog signal originating beyond the 100-km radius,
    whereas a digital signal originating inside, but near the edge of
    the radius, could not be measured. In most cases where a discrepancy
    exists between the anticipated signal type versus the measured
    signal type, it involves the detection of an analog signal when a
    digital signal was anticipated.

-   **Measured Power Level** -- This column presents the measured power
    level on each channel for each test site. Information regarding how
    these measurements were performed is provided in Appendix C.

-   **Occupied (O) & Available (A) Channels Reported by Each WSD** --
    This column indicates whether the WSD prototype reported the channel
    as occupied (indicated by an "O"). The status of those channels not
    reported as "occupied" were determined based on the rationale
    discussed below and indicated in the table by either an "A" to
    represent available or a "-" to represent indeterminate. This column
    may be further subdivided to indicate the results observed at each
    particular location where the device was tested. For example, L1/S1
    denotes those results obtained from the first scan performed at
    location 1 and similarly, L2/S2 denotes those results obtained from
    the second scan performed at location 2.

All of the prototype devices, except for the Motorola device when
operated in "Normal" (geo-location) mode, explicitly report only those
channels determined to be occupied. When operated in this mode, the
Motorola device reports those channels determined to be occupied and
also provides a list of the channels that it determines to be
"available".

When a prototype WSD scans for both ATSC and NTSC signals (even when it
requires separate scans to accomplish this) upon completion of a scan,
those channels not reported as occupied can reasonably be presumed to be
vacant or "available". However, if the scan is performed to detect only
channels occupied with one signal type (NTSC or ATSC), then the status
of the channels not reported as occupied is not readily apparent.
Examples of such scans performed in the field trials were: 1) those
scans performed with the Adaptrum prototype device for NTSC-occupied
channels only, 2) those scans performed with the Motorola prototype
device in "test" (sensing only) mode for ATSC-occupied channels only,
and 3) those scans performed with the I2R prototype device at test sites
1 and 2, where the device was operated in the incorrect mode for
detecting ATSC-occupied channels (in effect, resulting in NTSC-only
scans).

In populating the data tables reported for each test site, the following
approach was applied to determine the status of each channel based on
the scan results:

-   For all devices, those detection results indicated in the table by
    an "O" represent exactly what was reported by the device at the
    conclusion of each scan.

-   For those devices used to perform scans for both signal types (ATSC
    and NTSC) at the same location, the detection results indicated in
    the table by an "A" represent the channels that were not reported by
    the device as occupied under scans for both signals and thus were
    presumed to be vacant or "available". This condition is applicable
    to the following devices under the described conditions:

    -   The Adaptrum device in those locations where both ATSC and NTSC
        scans were performed,

    -   The I2R device at all sites except 1 and 2,

    -   The Motorola device when operated in the "Normal" mode
        (effectively),

    -   The Philips device in all configurations.

-   For those scans performed for only one signal type (ATSC or NTSC),
    determining whether a channel not reported as occupied would have
    been considered vacant (available) was often ambiguous and in some
    cases required that some judgment be applied. The following criteria
    was applied in making such channel status decisions:

    -   If the measured over-the-air signal type anticipated via the TV
        contours matched the signal type and was of the same type as
        that being detected by the device, then a channel not reported
        by the device as occupied was presumed to be available
        (indicated by "A" in the tables).

    -   If the measured signal type was of the same type as that being
        detected by the device (i.e., the measured signal was NTSC and
        the device was scanning for an NTSC signal), then regardless of
        the expected signal type, a channel not reported by the device
        as occupied was presumed to be available (indicated by "A" in
        the tables).

    -   If the expected signal type matched the measured signal type but
        was of the opposite type from that being detected by the device
        (i.e., the expected and measured signal were ATSC but the device
        was scanning for NTSC), then no presumption was made for those
        channels not reported by the device as occupied (indicated by
        "-" in the tables).

    -   If there was no expected signal type reported for the channel
        (no station assigned to the channel) and a signal type was not
        measured at the site, then no presumption was made regarding
        those channels not reported by the device as occupied (indicated
        in the tables by "-").[^38]

    -   For any other conditions for which ambiguity existed, no
        presumption was made regarding the channel status for those
        channels not reported by the device as occupied (indicated in
        the tables by "-").

Finally, there are some entries to the table where more than one station
within the 100-km search radius is assigned to a single channel. In
these cases, the signal type measured at the site took precedence when
assessing channel status.

## Test Site #1 -- Patapsco Valley State Park, Elkridge, MD

This site offered public access (Maryland State Park) and is
representative of a setting with difficult television reception
characteristics. The actual test site was a parking lot in the rear of
the park, adjacent to the Patapsco river bed, in a valley with rapidly
rising, wooded terrain to the Northeast (towards Baltimore) and
Southwest (towards Washington). The two test locations at this site were
in the same parking lot, separated by approximately 45.7 meters (150
feet).

## Test Site #2 - Aircraft Observation Area, Glen Burnie, MD

This is a public accessible site in the Baltimore suburbs, just south of
BWI/Thurgood Marshall Airport, under the approach path to runway
15R/33L. The channel occupancy measurements were performed from the west
side of the parking lot and the prototype field trials were performed
adjacent to the parking lot (location 1) and approximately 45.7 meters
(150 feet) southwest of the first location (location 2). Several
high-power TV signals were observed at this site.

## Test Site #3 -- Private Residence in Ellicott City, MD

This site is a two-story single-family home on a hilltop in the suburbs
of Baltimore, MD. The channel occupancy measurements were performed in
the driveway. The prototype trials were performed in the first floor
living area (location 1) and a second floor bedroom (location 2).
Because of the hilltop location, excellent television reception was
observed, including some stations for which the site was beyond their
service contour.

## Test Site #5 -- FCC Headquarters in Washington, DC

This site is a high-rise office building in downtown southwest
Washington, DC. Field trials of the WSD prototypes were performed in a
training room on the 12^th^ street level (ground floor) and in an area
on the 7^th^ floor near a window. Channel occupancy measurements were
performed at the same locations, using a bi-conical receive antenna
mounted on a tripod.

## Test Site #8 -- Intersection of Rt. 17 and Middle Point Rd., NE of Myersville

This site is northeast of Myersville, in rural western Maryland. This
was one of four sites recommended for measurement by MSTV.[^40] Channel
occupancy measurements were performed at the entrance of a long paved
driveway leading to a horse barn and the WSD prototype field trials were
performed at two locations in a field adjacent to the driveway,
separated by approximately 91.4 meters (300 feet).

## TV-Sensing (Channel Occupancy) Field Test Summary

This section provides a summary of the prototype TV WSD field trial
results obtained at the nine test sites.

In reducing the data from the TV sensing field tests it became obvious
that two available parameters can be used to define a set of conditions
which apply uniquely to each channel under consideration for "white"
space use. These two parameters have been labeled "Within Contour" and
"Viewable" in this report and each has a value of either yes (1) or no
(0). This binary combination yields four possible conditions that will
uniquely describe each TV channel at a particular location. These four
conditions are:

-   Condition I: the WSD is operating [within]{.underline} the service
    contour of a station assigned to the channel and the broadcast
    signal [can]{.underline} be displayed on a representative consumer
    TV receiver system (viewable).

-   Condition II: the WSD is operating [within]{.underline} the service
    contour of a station assigned to the channel but the broadcast
    signal [cannot]{.underline} be displayed on a representative
    consumer TV receiver system (not viewable).

-   Condition III: the WSD is operating [outside]{.underline} of the
    service contour of a station assigned to the channel but the
    broadcast signal [can]{.underline} be displayed on a representative
    consumer TV receiver system (viewable).

-   Condition IV: the WSD is operating [outside]{.underline} of the
    service contour of a station assigned to the channel and the
    broadcast signal [cannot]{.underline} be displayed on a
    representative consumer TV receiver system (not viewable).

Table 5-60, presented below, defines how each channel between 21 and 51
was categorized at each of the field trial sites. In this table, each
channel is assigned to one of the four conditions described above and
then further segmented according to the signal type utilizing the
channel (ATSC or NTSC).

Tables 5-61 through 5-66 provide the results from the field trials in
terms of the ability of each WSD prototype to correctly identify
Condition I, II, III or IV channels. For each condition, the number of
correct detections is shown as a function of the number of scans
performed. While this approach presumes that Condition II and III
channels represent occupied, rather than available channels, the
arithmetic complement of each reported result defines the performance
under the opposite presumption (*i.e.*, that they represent available
channels).

Table 5-67 shows the overall percentage of accurate signal detections
confined to those channels whose occupancy status is easily established
(Condition I and IV channels) over all nine of the test sites. The
results are presented for Condition I (occupied) ATSC (digital) and NTSC

It should be noted that the reported NTSC-detection performance may be
somewhat misleading since no consideration was given to the quality of
the analog picture when identifying "viewable" channels.

### Observations Based on Results

The TV-sensing field trial results indicate that the Motorola WSD, which
employs a geo-location/database look-up approach to identify occupied
and unoccupied TV channels, was the best overall performer with respect
to correctly determining occupied and unoccupied (available) TV channels
within TV station service contours. This prototype also employs a
spectrum sensing capability that was found to perform with less accuracy
than that of other devices. The combination of geo-location/database
look up and spectrum sensing techniques provide an acceptable mechanism
to allow for authorization of equipment today.

The results obtained from those WSD prototypes that rely solely on
spectrum sensing to identify occupied and unoccupied (available)
channels demonstrate the importance of correctly specifying a detection
sensitivity requirement. The Philips device, which demonstrated the most
sensitivity in the laboratory tests, also performed best with respect to
detecting occupied channels; however, it reported a very high percentage
of channels occupied that were potentially available. The Adaptrum and
I2R devices, which demonstrated less sensitivity in the laboratory
measurements, did much better at correctly determining available
channels but did not detect occupied channels with complete reliability.
Spectrum sensing worked to some degree and it may be possible to
authorize products that rely on spectrum sensing, in the future, if it
can be demonstrated that they will not interfere.

The comparative received power measurements performed at each test site
indicate that the difference in signal level between TV signals received
by a roof-top television antenna and those received by ground-proximate
antenna can vary between 0 and 34 dB, depending on the specific site
conditions and whether the WSD antenna is located indoors or outdoors
relative to the TV antenna.

# Wireless Microphone Measurements

## Wireless Microphone Laboratory Tests

### Introduction

The purpose of this part of the test project was to observe the
capabilities of the current white space device (WSD) prototypes to sense
Part 74 wireless microphones (WM) operating on broadcast television
channels at known signal levels with and without digital television
(DTV) signals on adjacent channels. Tests were performed with two
different types of microphones -- FM modulated and digitally
modulated.[^42] All of the tested microphones operate in a maximum 200
kHz authorized bandwidth segment within a TV channel. Each microphone
was limited to operation in a different subset of television channels 21
to 51; individual microphones were tested on frequencies within their
subset as shown in the test results. The test modulation was a 1000 Hz
tone at 24 kHz deviation. The two FM microphones had a 32 kHz pilot tone
and the digital microphone was encrypted. The measured modulated signal
for the FM microphones is shown in Figure 6-1 and the measured signal of
the digital microphone, which appears the same with or without
modulation, is shown in Figure 6-2.

The WSDs submitted by Microsoft and Philips were similar to those
submitted in the previous round of testing (Phase I) with respect to
their ability to detect wireless microphones with some modifications.
The changes eliminate the ability to select the type of signal (ATSC,
NTSC or wireless microphone) to search for and the identification of the
type of signal sensed. The versions of both of these WSDs examined in
the Phase II tests searched for all three types of signals on each scan
of a channel and indicated only whether the channel was occupied or
available on each scan or the probability of detection for the number of
scans selected. The Institute for Infocomm Research (I2R) device had the
capability to search for either DTV or wireless microphone signals. It
provided two scan modes -- "DTV" and "All" and two test modes -- "Lab"
and "Field". In the DTV scan mode it searched only for DTV signals and
in the "All" mode it searched only for microphones. The "Lab" test mode
was intended only for conducted bench testing and the "Field" mode was
intended only for reception of radiated signals with an antenna. The
test results were displayed as the probability of detection for the
number of scans selected.

### Test Procedure

Because of ambient emissions, direct pick-up and spurious radiated
emissions from the WSD systems, it was not possible to derive a clean
test signal on the bench by sampling the radiated signal from a wireless
microphone with a receive antenna and applying it to the antenna input
connector of the WSD. It was thus determined that the testing needed to
be performed with the wireless microphone in an anechoic chamber. This
approach avoided interference to the test from undesired signals, and
allowed a sample of the radiated signal from the microphone to be
received with an antenna in the chamber. This received signal was then
conducted by coaxial cable to the control room for connection to the
antenna terminal of the WSD, as shown in Figure 6-3.

#### Figure 6-3. Wireless Microphone Sensing Test Setup {#figure-6-3.-wireless-microphone-sensing-test-setup .unnumbered}

The WSDs were first tested for sensitivity to a wireless microphone
signal at a low, middle and high frequency within a TV channel with no
other signals present. The sensitivity threshold of a WSD was defined as
the lowest bandpower at which the microphone is detected on 10 of 10
successive scans. Each WSD was tested with the FM microphone modulated
and, in some cases, unmodulated. The digital microphone was tested with
or without modulation since there was no discernible difference between
the modulated and unmodulated signal or in the response of the WSDs to
the different signals. Testing was then performed with simulated DTV
signals located in various combinations of first and second adjacent
channels over a range of power levels. The simulated DTV signal was
obtained from a Rohde& Schwarz SFU signal generator. The spectral
characteristics of the simulated DTV signal with the emissions mask
specified in Section 73.622(h) of the Commission's rules are shown in
Figure 6.4.

### Test Results with Microphones and No DTV Signals

The sensitivity of the WSDs with no other signals present is shown in
tables 6-1 through 6-9. In most cases the FM wireless microphones were
tested at 50 kHz above the low frequency edge of the channel, in the
middle of the channel and 50 kHz below the high edge of the channel and,
because of its wider occupied bandwidth, the digital microphone was
tested 100 kHz above the low edge of the channel, in the middle of the
channel and 100 kHz below the high edge of the channel. It was not
always possible or considered necessary to test at all three frequencies
within a channel. The Shure UR1 H4 is the same basic model as the UR1 L3
tuned to a different frequency range.

### Test Results with Microphones and DTV Signals

The WSDs were tested to determine their ability to sense a wireless
microphone on a channel and with simulated DTV signals on various
combinations of first and second adjacent channels. The DTV signals were
provided at power levels -28, -53, -68 and -84 dBm, which represent a
high, medium, low and very low signal level. In most cases, it was found
that at DTV power levels of -68 dBm or higher, the WSDs would indicate
that the wireless microphone channel was occupied when no microphone
signal was present (false positive) and the Microsoft WSD would not
sense a wireless microphone signal at ‑80 dBm when the DTV signal power
was -28 dBm. In a few cases when the DTV signal was on the lower
adjacent channel, the WSDs would only indicate a false positive if the
DTV power was increased to a power level of -53 dBm or higher. Because
of test scheduling problems, the availability of test equipment or the
malfunctioning of a device, formal measurements for some test conditions
were not performed in all cases. Sensitivity was measured with DTV
signal levels below the power level that produced false positive
indications. The results are given in the tables below. For comparison,
the sensitivity without DTV signals is given in parentheses.

### Summary

All of the WSDs gave false positive indications of microphone detection
with DTV signal levels as low as -68 dBm in adjacent channels. The
Microsoft device also gave false negative indications with a DTV signal
level of -28 dBm in adjacent channels and a microphone power of -80 dBm.
The presence of DTV signals had little effect on the sensitivity of the
devices to the Lectrosonics microphone but there was insufficient data
to determine the effect of DTV signals on the sensitivity of the
Microsoft device to the Shure microphone. The sensitivity of the Philips
device to a modulated Shure microphone signal was not significantly
affected by the presence of DTV signals. However, when the Shure
microphone signal was unmodulated, the Philips device was significantly
less sensitive to a microphone in the middle of the TV channel with or
without DTV signals in adjacent channels.

## Wireless Microphone Field Tests 

### Introduction

Field tests were conducted to evaluate the performance of the WSDs in
detecting wireless microphones under real-world conditions. Arrangements
were made with the National Football League (NFL) and the ESPN Network
(ESPN) to perform tests before and during a pre-season football game at
FedEx Field in Landover, MD and with the Majestic Theatre in New York
City to perform tests before and during a performance of a Broadway
play.

ESPN offered to simulate a game day broadcast at FedEx Field from 10:30
AM in the morning until 5:00 PM in the afternoon before the start of the
game. During this time they would turn all their wireless microphones on
or off upon request. The WSDs were operated and spectrum measurements
were taken at four different locations at the venue: on the east (home
field) side of the playing field from 10:30 AM to 12:00 PM, at the
"tailgate" area outside the stadium from 12:40 PM to 2:00 PM, on the
upper deck from 2:20 PM to 3:30 PM, and in the Press Box from 4:00 PM
on. At 5:00 PM, ESPN was required to cease transmissions so the NFL
could set up and test their wireless microphones for use during the
game, which began at 7:00 PM. From 6:20 PM to 7:00 PM during pre-game
activities and from 7:20 PM to 7:45 PM during the first quarter of the
game, the WSDs were operated and spectrum measurements taken.

At the Majestic Theatre, WSD tests and spectrum measurements were taken
at three different locations before the performance: on the sidewalk at
the entrance to the theater, in the middle of the mezzanine and in the
orchestra seating area. Measurements were also taken at one location
during the performance (entrance ramp to the orchestra seating area).
Before the performance, measurements were performed with the wireless
microphones to be used during the show turned on and off upon request.

### Test Procedure

At each location the Philips and I2R WSDs were set up with their receive
antennas located approximately 2 meters from the wireless microphone
base unit. The frequency spectrum was scanned by the WSDs from TV
channels 21 to 51 with the wireless microphones turned on and off. The
channels indicated as occupied by the WSD were recorded in each case.
The frequency spectrum was also observed and recorded with a spectrum
analyzer using a ground plane vertical antenna with a gain of
approximately 0 dBi from channels 21 to 51.

### Test Results

Tables 6-29 through 6-48 show the results of the WSD scans. "X"
indicates the channels on which ESPN, the NFL or the Majestic Theatre
were operating wireless microphones and the channels which the WSDs
reported as occupied with the microphones off and on. The channels
indicated as NFL channels are those on which it appears that there were
NFL microphones based on the spectrum scans. The spectrum plots obtained
with the spectrum analyzer under the same conditions are given in
Appendix A for FedEx Field and Appendix B for the Majestic Theatre.

Additionally, during two of the field tests of the of the white space
devices' ability to detect TV signals, brief tests were conducted to
check the ability of the Philips and the I2R devices to detect wireless
microphones. At the Portals location, it was found that the Philips
device could detect the Shure UR1 and the Lectrosonics UM 700
microphones at distances up to 30.5 meters (100 feet) within the
building with intervening walls. The I2R device reported detection of
the Shure UR1 with less than 100% probability at 4.6 meters (15 feet) or
less but could not detect the microphone at 30.5 meters (100 feet). The
I2R device reported detection of the Lectrosonics unit with 100 %
probability at distances up to 6.1 meters (20 feet) but with only 60%
probability at distances of 30.5 meters (100 feet) and 61 meters (200
feet). At the #3 test site, a residential location, the Philips device
could not be tested because it indicated that all channels were
occupied. At this location, the I2R device could not detect the Shure
UR2 even as close as 1.5 meters (5 feet) but it could detect the
Lectrosonics UM 700 at distances up to 15.2 meters (50 feet) where the
reported probability of detection decreased to 50%.

### Summary

Wireless microphone sensing tests were performed with the I2R and
Philips devices at 2 locations. The tests were conducted first with
microphones off, and then turned on, in pre-determined channels to
determine if the devices could sense the presence of wireless
microphones. At both sites and all the test locations, the Philips
device reported all the channels on which the microphones were
designated to transmit as occupied whether the microphone was
transmitting or not. The I2R device indicated several channels as
available even when the microphones were on.

    requested comment as to whether, if unused TV spectrum were made
    available on a licensed basis, licensed devices should be required
    to incorporate the same type of interference avoidance mechanisms
    and be subject to the same low power limits that it proposed for
    unlicensed devices.

[^17]: The Adaptrum device was found to be particularly prone to false
    detections on channel 36, likely because of the presence of an OTA
    signal on the channel. Thus, channel 37 was used as the middle test
    channel for this device.

[^37]: It is noted that the test receiving system used herein varies
    from both the analog and digital TV planning factors by
    approximately 4.3 dB (the receive antenna used in the field tests
    provides 7 dBd of gain rather than the 10 dBd used in the planning
    factors and the line loss of the field test receive system was about
    5.3 dB rather than 4 dB used in the planning factors). Therefore,
    the test system provided 4.3 dB less signal to the receiver than
    would a system adhering to the planning factors.

[^38]: In these cases it could not be determined with certainty that a
    signal of the opposite type was not present at levels below the
    measurement threshold but still within the detection range of the
    device.
