dB Wanted signal @ -82 dBm. Undesired signal is an 802.15.4
modulated channel, stepped through all channels from 2405
to 2480 MHz. Signal level for PER = 1%. Values are
estimated.
Co-channel rejection -6 dB Wanted signal @ -82 dBm. Undesired signal is 802.15.4
modulated at the same frequency as the desired signal. Signal
level for PER = 1%.
