**APPENDIX H \-- A METHOD OF CONVERTING PERCENTAGE OF UNAVAILABLE TIME
INTO A CARRIER-TO-INTERFERENCE RATIO**

This appendix presents a method for determining the relationship between
DBS service outage time and a DBS system's carrier-to-noise plus
interference ratio (C/N+I). Specifically, this method can be used to
determine the C/I that a terrestrial system needs to meet in relation to
a DBS satellite system to keep service disruptions of the satellite
system to a certain amount of outage time. In this case the terrestrial
system represents the interference and the satellite system represents
the desired carrier.

The availability of a satellite space-to-Earth link is defined as the
total amount of time that the satellite service is available to the user
without disruption. Conversely, the unavailability of that same link is
the total time during which the user is without service (outage).
Generally, availability and unavailability are expressed in terms of
percentage of time of an average year (8765.76 hours) or the worst month
in an average year.[^1] These two variables are complementary and always
sum to 100 percent. For example if a satellite system has an
availability of 99.7%, its unavailability is 0.3% which equates to total
outage time of 26.3 hours averaged over a year.

In a shared environment (satellite and terrestrial service), the total
unavailability can be attributed to two sources: natural propagation
phenomenon such as precipitation (*e.g.*, rain) in the space-to-earth
path and external radio interference. In the frequency bands used by DBS
for downlink (12.2-12.7 GHz), the predominant propagation impairment is
rain attenuation in the space-to-earth slant path.[^2] The amount of
service outage caused by rain can be estimated using the prediction
procedures of ITU-R Recommendation P.618-6. This rain attenuation model
predicts, for a given geographic area, the average service outage time
over an average year for a specific level of precipitation attenuation
along the space-to-earth slant path.

To determine the portion of the total C/I that is attributable to a
terrestrial system, we first establish the amount of outage time of the
DBS space-to-earth link that is caused by precipitation only. This
outage time is directly dependent on the link margin of the
space-to-earth link, which is calculated from the system's link power
budget. Link margin is the amount of power received at the earth station
receiver above its operating threshold that is designed into the
satellite link to overcome the effects of rain and other impediments.
During rain, the satellite link is affected in two ways: the carrier
signal strength is attenuated due to rain and the rain causes an
increase in the system's noise temperature. If the rain attenuation and
earth station G/T (gain / system noise temperature) degradation cause a
reduction to the carrier-to-noise (C/N) power that exceeds the available
link margin, the satellite link will experience an outage. The amount of
attenuation due to rain that causes an outage is referred to as the rain
margin.

The satellite link budget (carrier-to-noise plus interference ratio) and
the associated rain margin can be derived from the parameters identified
in Table B-1. It is evident from the table that the rain margin depends
on the DBS satellite E.I.R.P. in the direction of the receiving earth
station, the free space path loss, the earth station antenna
gain-to-system noise temperature (G/T) ratio and the operating
threshold. Once the link margin is known, one can proceed to determine
the rain margin. This is accomplished by adding a rain attenuation term
to the equation used to find the clear-sky carrier-to-noise ratio to
instead find a rainy-sky carrier-to-noise ratio. Additionally, the G/T
must be recalculated to account for the increase in atmospheric noise
due to the rain. Thus, the G/T will be reduced during a rain event and
the rain margin will be less than the link margin.

Once the rain margin is determined, the expected outage time of a
satellite link in an average year or in the worst month can be computed
using the prediction method contained in ITU-R Recommendation P.618-6.
This recommendation entitled "Propagation Data and Prediction Method
required for the Design of Earth-Space Telecommunication Systems"
provides a procedure to estimate the long-term statistics of the
space-to-earth path precipitation attenuation and the associated
percentage of outage time.

Now that the percentage of outage time due solely to rain is known, we
can reverse the procedure to determine the minimum C/I that a
terrestrial system must maintain to effect a specific amount of
additional outage time on the satellite system. First, the additional
outage time must be determined, either as a percentage of additional
outage time or a number of minutes per time period. This additional
outage time can then be added to the outage time due to rain only to
find the 'equivalent unavailability.' For example, if a satellite
space-to-earth link has an unavailability of 0.3% and the minimum C/I
for the terrestrial system to cause no more than an additional 10%
outage is to be determined, the equivalent unavailability would be 0.33%
(0.3 \* 1.1). Using the equivalent unavailability, the ITU rain model
can be used to find the corresponding 'equivalent rain margin.' That is,
the ITU model can be used to find the amount of attenuation associated
with the increased outage time. This change in attenuation is attributed
to interference from the terrestrial system.

The C/I for the terrestrial system can now be found by modifying the
methodology used to determine the satellite link budget
(carrier-to-noise plus interference ratio). The terrestrial system is
factored into the link budget by adding a term representing its C/I. By
using the equivalent rain margin in the link budget, we find an
'equivalent link margin.' We can then find the C/I of the terrestrial
system that causes the reduction of the equivalent link margin to zero.
This is the minimum C/I that the terrestrial system must maintain to
cause no more than the amount of additional outage time chosen.

It is important to note that the above methodology results in the
rainy-sky C/I for the terrestrial service interference, which would
produce the additional outage time at the DBS earth station. The reason
for calculating the rainy-sky C/I is based on the assumption that in a
typical satellite path, rain cells in the space-to-earth slant path are
generally to the south of the earth station location. Because the
terrestrial interfering path generally emanates from the north of the
DBS earth station location, it will usually not be in the rain cell.
Thus, at the time when a rain cell in the space-to-earth path attenuates
a DBS signal, the terrestrial signal will not similarly be attenuated.
Therefore, the calculated C/I is performed by not fading the terrestrial
signal with rain.

Table B-2 provides an example of the process described above.

**Calculation method**:

(A) Calculate the distance and elevation angle between satellite and
    earth station using the satellite longitude (1) and the earth
    station location (2).

(B) Calculate the free space transmission loss using the distance (A)
    and the operating frequency (5).

(C) Calculate DBS antenna gain using the operating frequency (5) and the
    earth station antenna diameter (8).

(D) Calculate the clear-sky G/T ratio using the antenna gain (C) and the
    clear-sky earth station system noise temperature (10).

(E) Calculate the clear-sky carrier-to-noise ratio using the E.I.R.P.
    (4), free space transmission loss (B), earth station antenna
    pointing loss (9), clear-sky G/T (D), receiver noise bandwidth (7),
    Boltzman's constant (14) and atmospheric absorption (11).

(F) Calculate the clear-sky carrier-to-noise plus interference ratio
    using the clear-sky carrier-to-noise ratio (E), the
    carrier-to-interference ration from other assignments in the BSS
    plan (12), and the clear-sky feeder link carrier-to-interference
    ratio (13)

(G) Calculate the link and rain margins using the clear-sky
    carrier-to-noise plus interference ratio (F) and the operating
    threshold (6).

(H) Calculate the satellite link unavailability using ITU-R
    Recommendation P.618-6, the rain margin (G), earth station location
    (2), earth station elevation angle (A), AMSL (3), and operating
    frequency (5).

(I) Determine the acceptable increase in unavailability due to
    terrestrial service interference and calculate equivalent
    unavailability of the satellite by adding the satellite link
    unavailability (H) and the increase in unavailability due to
    terrestrial interference.

(J) Determine the equivalent rain margin using the equivalent
    unavailability (I) and ITU-R Recommendation P.618-6.

(K) Determine the C/I for the terrestrial interference using the
    equivalent rain margin (J) in the step (G) calculation.
