2 Adjacent channel selectivity

The adjacent channel selectivity requirement is 21.7 dB above the minimum wanted signal level and applies in the adjacent 50 MHz of the licence under which the radiocommunications receiver operates.

Note: When using the adjacent channel selectivity requirement to calculate the maximum tolerable interference level, the calculated level is the maximum power within the adjacent 50 MHz. For example, a receiver complying with the notional receiver performance level will be able to tolerate an interference power level of -63.3 dBm/50 MHz in the adjacent 50 MHz, measured at the input of the receiver.
