10 Trunked Land-Mobile Base Station Receivers
(1) The protection requirements for base station radiocommunications receivers operating in: (a) before 1 July 2024 – the 820 MHz to 825 MHz frequency band; and (b) the 806 MHz to 809 MHz frequency band; for the percentage of time specified in RALI LM 8, are: (c) a wanted signal to unwanted signal level ratio at the receiver input not less than the wanted to unwanted ratio specified in RALI LM 8; and (d) a blocking level at the receiver input not exceeding the blocking level specified in RALI LM 8. (2) The radiofrequency selectivity performance of the base station radiocommunications receiver may be assumed to be at least equal to the performance of a cavity filter with a response as specified in RALI LM 8 tuned to the operating frequency of that receiver. The base station receiver intermediate frequency bandwidth may be assumed to be that specified in RALI LM 8. The base station receiver antenna may be assumed to have a response equivalent to the notional antenna specified in RALI LM 8.
