Appendix A Technical Performance of Receiver
and Transmitter
The technical specifications of BTS receivers and transmitters comply with or
surpass all the performance requirements defined in the IS -97-D Recommended
Minimum Performance Standards for cdma2000 Spread Spectrum Base Stations
.
A.1 Performance of Receiver
A.1.1 Frequency Coverage
450MHz band: 450 - 460MHz
800MHz band: 824 - 849MHz
1900MHz band: 1850 - 1910MHz
A.1.2 Access Probe Acquisition
The access probe failure rates under the reliability of 90% is below the maximum
values listed in Table A-1:

A.1.3 R-TCH Demodulation Performance
I. Performance of R-TCH in Additive White Gaussian Noise (AWGN)
The demod ulation performance of the Reverse Traffic Channel in AWGN (no fading
or multipath) environment is determined by the frame error rate (FER) at specified
Eb/N0 value. FER of 4 possible data rates should be calculated respectively. With
95% confidence, the FER for each data rate does not exceed the two given FERs in
Table A -2 t o Table A -9, which adopt the linear interpolation in the form of Log
10
(FER).
