Description
Signal
Displays the Relative Signal Strength Indicator (RSSI) of the signal transmitted between
the AP and wearable terminal. As long as the Signal Quality icon is green the AP
association is not jeopardized. If the icon is red (poor signal), an association with a
different AP could be warranted to improve the signal. The signal strength icon changes
depending on the signal strength.
Excellent Signal
Very Good Signal
Good Signal
Fair Signal
Poor Signal
Out of Range (no signal)
The radio card is off or there is a problem communicating with the radio card.
Status
Indicates if the wearable terminal is associated with the AP.
Signal Quality
Displays a text format of the Signal icon.
Tx Retries
Displays a percentage of the number of data packets the wearable terminal retransmits.
The fewer transmit retries, the more efficient the wireless network is.
Missed Beacons
Displays a percentage of the amount of beacons the wearable terminal missed. The
fewer transmit retries, the more efficient the wireless network is. Beacons are uniform
system packets broadcast by the AP to keep the network synchronized.
Signal Level
Displays the AP signal level in decibels per milliwatt (dBm).
Noise Level
Displays the background interference (noise) level in decibels per milliwatt (dBm).
SNR
Displays the access point/wearable terminal Signal to Noise Ratio (SNR) of signal
strength to noise (interference) in decibels per milliwatt (dBm).
