Wireless Communications Systems - Performance in Noise and Interference - Limited Situations - Recommended Methods for Technology - Independent Modeling@ Simulation@ and Verifications (Addendum No. 1 to TSB-88-B)
This document is an addendum to TIA Telecommunications Service Bulletin TSB-88-B. It is intended to clarify the default ENBW of analog FM receivers that are deployed in the VHF and UHF bands as indicated in Annex A and Table 2.? Radios in the VHF (high band) that utilize ?? 5 kHz deviation often use an IF bandwidth of 16 kHz? Radios in the UHF (380 - 512 MHz) that utilize ?? 5 kHz deviation often use an IF bandwidth of 16 kHz.? Radios in the 800 MHz band but not the NPSPAC band that utilize ?? 5 kHz deviation often use an IF bandwidth of 16 kHz? Radios in the 800 MHz band that operate in the NPSPAC band with ?? 4 kHz deviation require a narrower IF bandwidth to achieve a 20 dB ACRR.? Narrow analog FM radios do not provide 60 dB ACRR unless a very narrow ENBW in utilized. Some manufacturers do not provide this capability as it is not required by TIA/ANSI 603C.Various editorial errors are also corrected.
