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- Recommended Methods for Technology - Independent Modeling, Simulation, and Verifications Addendum No. 1 to TSB-88-B [Superseded By: TIA TSB-88.1-C ERTA, TIA TS
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.
