[1] requires 30 dB
Wanted signal @ -82 dBm,
adjacent modulated channel at
± 10 MHz, PER = 1 %, as
specified by [1]
[1] requires 30 dB
Wanted signal 3 dB above the
sensitivity level, CW jammer,
PER = 1%.
Ratio between sensitivity for an
unwanted frequency to the
sensitivity in the wanted channel.
The signal source is a 802.15.4
modulated channel, swept over
all channels from 2405 to 2480
MHz. Signal level for PER = 1%
Adjacent channels and image
channel are excluded.
