Where:
Pout = Total output power of the MVDDS transmitter (watts) into antenna
Gm ([THETA]m,[PHI]m = Gain of the MVDDS antenna in the direction of the DBS earth station
Ge ([THETA]e,[PHI]e = Gain of the earth station in the direction of the MVDDS antenna
I = Interference scaling factor for the earth station (1 dB for MVDDS transmitters employing the modulation discussed in Section 3.1.5 of the MITRE Report (i.e., a QPSK modulated signal passed through a square-root raised cosine filter). For other modulation and filtering schemes, the interference scaling factor can be measured using the procedures described in Appendix A of the MITRE Report available at http://www.fcc.gov/oet/info/mitrereport/mitrereport_4_01.pdf).
Ge, max = Maximum gain of the DBS earth station
d = the distance between the MVDDS transmitting antenna and the DBS earth station (meters)
Fixed-to-fixed-145 km;
Fixed-to-mobile-113 km;
Mobile-to-mobile-81 km
Note to paragraph (c)(3)(i): Multiple address systems employing only remote stations will be treated as mobile for the purposes of determining the appropriate separation. For mobile operation, the mileage is measured from the reference point specified on the license application. For fixed operation on subfrequencies in accordance with § 101.147 the mileage also is measured from the reference point specified on the license application.
