45、r at the nominal frequency of the receiver, modulated with the normal modulation (see clause 5.1.2) which will, without interference, produce after demodulation a data signal with either a specified Bit Error Rate (BER) or a Frame Error Rate (FER).

47、ses. 4.3.3 Adjacent channel selectivity The adjacent channel selectivity is a measure of the capability of the receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of an unwanted signal that differs in frequency from the wanted signal by an amount e
48、qual to the adjacent channel separation for which the equipment is intended. For IEEE 802.11 4 systems using direct sequence spread spectrum, the adjacent channel is defined as the non-overlapping channel which is at least 30 MHz separated from the wanted signal. For IEEE 802.11b 5 and IEEE 802.11g
49、6 systems, the adjacent channel is defined as the non-overlapping channel which is at least 25 MHz separated from the wanted signal. For IEEE 802.11a 7, IEEE 802.11h and Hiperlan 2 9, the adjacent channel is defined as the channel which is 20 MHz separated from the wanted signal. 4.4 Reference values 4.4.1 IEEE 802.11 - FH systems The minimum receiver sensitivity shall not be less than the reference values as stated in table 4.
