Additional Considerations for Mobile Operation
Consider the following key points for all mobile installations:
SNR
(Signal-to-Noise Ratio)
Strong signal (bench
setting): 25-28 dB
Operational: 3-30 dB
Typ. System: 10-20 dB
A low SNR may be caused by
noise or interfering signals.
TX Freq. Offset
0-22,875 Hz
Adjusts to accommodate what
is expected by the AP.
RX Freq. Offset
0-22,875 Hz
Adjusts to accommodate what
is expected by the AP.
Total FEC Count

Corrected FEC Count
Varies
Uncorrected FEC

Current AP Name
Device name of
associated AP
Typically set to reflect the
application or system the radio
is used in.

MAC ADDR
MAC Address of

address exactly
RSSI
(Received Signal
Strength Indication)
Varies
The less negative an RSSI
reading, the stronger the
signal (i.e., -75 dBm is
stronger than -85 dBm).
SNR
Signal-to-Noise Ratio
Strong signal (bench):
25-28 dB
Operational: 3-30 dB
Typ. System:10-20 dB
A low SNR may be caused by
noise or interfering signals.
Downlink
Varies
QPSK/FEC-3/4 Preferred
Uplink
Varies
