66. APPENDIX B - Britecell input power level setting
66.1. Down link power levels
In order to achieve spurious products below the limits set forth in various
governmental specifications (eg. -36 dBm for GSM900, –30 dBm for GSM1800) the
input power at the TFL downlink input port should be set according to the
following table. FCC specifications (-13 dBm- AMPS, PCS) are somewhat more
lenient and are also dependent on spectral mask requirements.
