Transmit Power Steps
The transmit power level can now be programmed in 1 dB steps from +15 to 26 dBm. The
ability to set the transmit power in 1 dB steps is particularly useful in high-density
environments, where site-to-site interference may be a problem.
RSSI, SQ and RNA on CCU
The CCU now measures and reports RSSI, SQ and RNA on a per-EUM basis. RSSI is the
received power measured when a packet is received from a particular EUM. SQ is the signal
quality measured at the same time, and RNA is the difference between the RSSI and the noise
floor which, in turn, is measured between packet transmissions and receptions.
These statistics now appear in the Watch Results display, and the RSSI display for the EUM
that is under watch. Columns have also been added to the Registration (Air) and ARP Map
tables for RSSI, SQ and RNA for each EUM.
