3.3.2. Minimum input level sensitivity
For all channels, the Frame-Error Rate (FER) shall be less than 8*10
-2
at a frame length of 1024 bytes for:
•
an input level of -91dBm at 25ºC or -89dBm at full operational temperature range,
measured at the antenna connector using 1Mbit/s DBPSK modulation
•
an input level of -88dBm at 25ºC or -86dBm at full operational temperature range,
measured at the antenna connector using 2Mbit/s DQPSK modulation
•
an input level of -85dBm at 25ºC or -83dBm at full operational temperature range,
measured at the antenna connector using 5.5Mbit/s CCK modulation.
•
an input level of -82dBm at 25ºC or -80dBm at full operational temperature range,
measured at the antenna connector using 11Mbit/s CCK modulation.
The test for the minimum input level sensitivity shall be conducted with the Carrier Detect threshold set less
than –95dBm.
3.3.3. Maximum input level
The FER shall be less than 8*10
-2
(1024 byte frames) for a maximum input level of -4Bm measured at the
antenna connector. This applies to all modulation types and data rates.
3.3.4. Over-voltage protection
The receiver shall not be damaged by over-driving levels up to +17dBm at the antenna connector. No DC
voltage shall be exposed to the antenna connector.
3.3.5. Out-of-band signal rejection
A Mini-PCI board signal is applied together with two Continuous Wave (CW) interference signals at the receiver
antenna input. The level of the Mini-PCI board signal is -55dBm. The CW interference signals have equal level
and 1.2MHz frequency distance. The maximum level of each of the two interfering CW signals for a FER better
than 8*10
-2
(1024 byte frames) is shown in Table 1 as a function of the average frequency of both interfering
frequencies.
Average frequency of interferers max. level of each interferer,
<1.0GHz -6dBm
1.0-2.0 GHz -10dBm
2.0-2.35 GHz -26dBm
2.55-2.9 GHz -26dBm
>2.9 GHz -10dBm

3.3.6. Irreducible Frame Error Ratio
The Irreducible FER (1024 byte frames) in an RF-clean environment (anechoic chamber) at nominal
temperature between two Network Interfaces one meter apart using 2Mbit/s DQPSK will be better than 1*10
-8
