¥ Average SNRShows average signal-to-noise-ratio (SNR) of

received signals, displayed in dB. This is a measurement of the

quality of the incoming signal. It is possible for incoming sig-

nals to be strong, yet be affected by interference or other noise,

resulting in a low SNR. Use this parameter to help determine the

actual quality of signals.

Radio DetailsThis selection presents a screen (

¥ RSSIShows received signal strength indication (RSSI) in

dBm.

SNRShows signal-to-noise ratio (SNR) in dB.

¥ TX Frequency OffsetShows the RF carrier shift of the Remotes

transmitter, measured in Hertz (Hz). The transmitted frequency

is continually reviewed and adjusted to agree with what the AP

expects to see. This optimization results in more efficient oper-

ation, corrects for doppler shift, and results in higher throughput

between AP and Remote stations.

RX Frequency OffsetThis is a measurement of how far in fre-

quency the Remotes receiver has shifted (in Hz) to accommo-

date the incoming signal from the AP.

Total FEC CountThis parameter shows the total number of For-

ward Error Correction (FEC) blocks handled by the radio.

Corrected FEC CountDisplays the number of errored blocks

corrected with FEC by the radio.

Uncorrected FEC CountShows the number of errored blocks that

cant be corrected with FEC by the radio.
