2.3

Power Supply (VCC)

Stable DC power supply to the card is required.
During operation, the current drawn from VCC can vary by some order of magnitude,especially due to a surging consumption profile with unmatched antenna.
It is important that the system power supply circuit is able to support the peak power
demand. Otherwise, unexpected anomalies may happen. E.g. the established COM(/dev/tty/ACM*) port may disappear etc.
According to PCI Express Mini Card standard, the peak current is 2,750 mA, the7NaviSys Technology - Your Location Partner

Data Sheet - WW-4131

normal current is 1,100mA.

2.4

Universal Serial Bus (USB_DM, USB_DP)

WW-4131 includes a USB 2.0 High Speed (480Mbit/s) interface. The USB interface isprimarily intended for use as command and data interface and for downloading
firmware. It is the main interface for transferring high speed data between a WW-4131
card and a host processor.
By default, WW-4131 enumerates, i.e., registers with the USB host, as a USB device
supporting two separate functions/ports. Following is the Default Composite
Communication enumeration.

Figure 1: Default USB interface enumeration
2.4.1

Windows USB Interface

Under Microsoft® Windows 7, the default USB device implements a CDC ACM port(a virtual USB COM port), as well as a CDC ECM port (wireless Ethernet adapter).
Each interface is controlled by a separate device driver running on the Windows host. These
drivers can be the standard USB drivers integrated in Windows. The driver configuration files
for Windows (.inf files) are supplied by Gemalto M2M and need to be installed before the USB
interface device can be used.

A user can concurrently use the AT command interface on one port andPacket-Switched / Circuit-Switched Data communication on another port.
2.4.2

Linux USB Interface

Some Linux systems - e.g., Ubuntu 10.04 LTS - will automatically detect andenumerate the USB device:
If WW-4131 is powered on, the following port will be created based on the “cdc_acm”
USB host driver available by default for the Ubuntu Linux system:/dev/ttyACM0 --> CDC ACM port
In addition, if the USB host drivers “usbnet” and “cdc-ether” are installed in the Linux system,
an Ethernet port (“USB0”) will be created and a default IP address in the range 192.168.15.1/
255 will be assigned to the interface. Information about the Ethernet port can be displayedusing the command ifconfig, and the port can be found under:/dev/bus/usb/devices/usb0 --> CDC ECM port
Please note that with every module re-start the USB port will be re-enumerated.

With other Linux systems the USB device (i.e. WW-4131) may not automatically be detected
and enumerated. For these systems possible USB host drivers like "cdc_acm", “usbnet” and“cdc_ether” compiled as loadable module may have to be loaded to create the ports. Please
note that the command to load such a driver module may vary for different Linux distributions.
Please also note that each USB bus has different numbers and different devices generated,so the port numbers depend on the number of USB hosts, ports on PC main board, or theexternal USB hub.

2.6

Data Sheet - WW-4131(U)SIM interface (SIM_VCC, SIM_DATA, SIM_CLK, SIM_RESET)

3GPP 31.102 and ETSI 102 221 compatible UICC/SIM/USIM interface is provided on thegold finger pins. Option of an on-board SIM card holder is provided. The high-speed
SIM/ME interface is implemented as well as automatic detection of the required SIM
supporting voltage.
Both 1.8 V and 3 V SIM types are supported (1.8 V and 3 V ME). Activation anddeactivation with automatic voltage switch from 1.8 V to 3 V is implemented,
according to ISO-IEC 7816-3 specifications. The SIM driver supports the PPS(Protocol and Parameter Selection) procedure for baud-rate selection, according to
the values proposed by the SIM Card.
The total cable length between the ELS31-J module pads (soldered on the WW-4131
miniPCIe card) and the pads of an external SIM card holder must not exceed 100mm
in order to meet the specifications of 3GPP TS 51.010-1 and to satisfy the requirements of
EMC compliance.

To avoid possible cross-talk from the SIM_CLK signal to the SIM_DATA signal, be
careful that both lines are not placed closely next to each other. A useful approach isusing a GND line to shield the SIM_CLK line from the SIM_DATA line.
If on-card SIM card holder option is available, external SIM card holder is
unnecessary.
Simultaneous operation of an external and the onboard SIM/UICC is not possible.
Only one SIM/UICC card must be connected to the ELS31-J module.
No guarantee can be given, nor any liability accepted, if loss of data is
encountered after removing the SIM card during operation. Also, no guarantee
can be given for properly initializing any SIM card that the user inserts after
having removed the SIM card during operation. In this case, the miniPCIe must10

NaviSys Technology - Your Location Partner

Data Sheet - WW-4131

be restarted.

2.7

Remote Host Wakeup (nWAKE)

While a USB connection is active, the card will never switch into SLEEP mode. Only if
the USB interface is in Suspended state, the module is able to switch into SLEEP
mode thereby saving power. There are two possibilities to enable power reduction
mechanisms:
Recommended implementation of USB Suspend/Resume/Remote Wakeup

The USB host should be able to bring its USB interface into the Suspended state as
described in the “Universal Serial Bus Specification Revision 2.0”. On incoming calls
and other events WW-4131 will then generate a Remote Wakeup request to resume
the USB host controller.
See also “USB Specification Revision 2.0”, Section 10.2.7, p.282.
"If USB System wishes to place the bus in the Suspended state, it commands the
Host Controller to stop all bus traffic, including SOFs. This causes all USB devices toenter the Suspended state. In this state, the USB System may enable the Host
Controller to respond to bus wakeup events. This allows the Host Controller to
respond to bus wakeup signaling to restart the host system."
Implementation for legacy USB applications not supporting USB Suspend/Resume

As an alternative to the regular USB suspend and resume mechanism it is possible toemploy the nWake (RING) line to wake up the host application in case of incoming
SMS or events signalized by URCs while the USB interface is in detached state. Every
wakeup event will force a new USB enumeration. Therefore, the external application
has to carefully consider the enumeration timings to avoid losing any signaled events.
The wakeup signal is connected to an internal ring (RI) pin. That is to say, an incoming
SMS message will bring this nWAKE pin up and down as shown below.
1s

nWAKE OFFnWAKE ON0time [s]11NaviSys Technology - Your Location Partner

Data Sheet - WW-4131

SMS arrives

Please note that the SMS ring line function may not be supported by earlier samples.
At the moment of preparing this document (V0.1), this function is ready.
Please also note that for SMS, the ring signal comes only when there is no unread
SMS messages in the queue. That is to say, there would be no ring signal if there is
any unread SMS messages.
To make sure the ring signal always comes, it is the user’s sole obligation to readany incoming SMS messages.

Please note that this pin is not connected (NC) for some sub-models. Please see
section 8 Ordering Information for the details.
The suggested pin connection is shown below.

UART TTL/RS232 Interface

In addition to standard USB interface, WW-4131 optionally supports UART TTL or
RS232 interfaces for such kind of applications. For this application, WW-4131
becomes a powerful modem under your command.
Totally 4 pins are supported – TX, RX, CTS, RTS. Please note that UART/RS232 is
not a standard interface of mini PCIe. These 4 pins are proprietary. Please refer to thespec for correct connection.

3 RF Interface
3.1

Antenna Connectors

WW-4131 includes two RF connectors for host-supplied antennas.

As shown above, there are two antenna connectors for this card.
 The primary (main) antenna interface is used for Tx/Rx.
 The secondary (auxiliary) antenna interface is used for Rx diversity antenna.
 The integrated diversity receiver provides improved wireless link quality andreliability on all 4G operating bands.
 Two antennas may experience different interference effects (signal delay,
distortion etc.). When one antenna receives a degraded signal, anotherone may not be similarly affected.
 The antenna for the Rx diversity connected to the secondary antennaconnector should be carefully separated from the main Tx/Rx antennaconnected to the primary antenna connector: the distance between the
two antennas should be at least greater than half a wavelength of thelowest used frequency (i.e. distance greater than ~20 cm, for 4G low
bands) to distinguish between different multipath channels, for proper
spatial diversity implementation.


The WWAN connectors are basically for cellular communications.
 The RF interface has an impedance of 50ohm. WW-4131 is capable ofsustaining a total mismatch at the antenna lines without any damage, evenwhen transmitting at maximum RF power.
 The external antenna must be matched properly to achieve best performance
regarding radiated power, modulation accuracy and harmonic suppression.

The final operating temperature depends on the physical environment. Parameterslike antenna performance, cellular signal quality, loading, heat dissipation etc. allaffect the physical operating temperature.

6.3

ESD Sensitive

WW-4131 cards contain highly sensitive electronic circuitry and areElectrostatic Sensitive Devices (ESD). Handling WW-4131 cards without
proper ESD protection may destroy or damage them permanently.
WW-4131 cards are Electrostatic Sensitive Devices (ESD) and require special
ESD precautions typically applied to ESD sensitive components.



Proper ESD handling and packaging procedures must be applied throughout theprocessing, handling and operation of any application that incorporates WW-4131
cards.



ESD precautions should be implemented on the application board where themodule is mounted.
