Tx Power Settings
The Maximum transmit power is limited by several factors including the number of channels and the selected
channel. Your regulatory domain may limit the maximum EIRP for certain frequency ranges. On very short links,
decrease Tx power to avoid saturating the receiver.
Antenna Gain Settings
Antenna Gain is fixed on B5 and B5-Lite backhaul radios, so no antenna gain entry field is shown. However, Antenna
Gain is configurable on the B5c because it can be paired with antennas which have various gain values. The
Antenna Gain value is used for two purposes:
To limit the maximum Tx power for each channel based on regulatory domain rules in your country.1.
To calculate the Rx Signal target on the Dashboard. The target will be incorrect if the gain value is inaccurate.2.

Performance Graphs
The Dashboard Performance panel contains two graphs (IP Throughput and PHY PER) that can each be selected by
clicking on the circles at the bottom of the graph. Verify that the PER is below 2% on average after association. More

MIMO Status
The Dashboard MIMO Status tables show the SNR per chain and the MCS per stream. If the SNR is low for a
particular channel, try changing channels or move to a smaller channel width. Note that PER and SNR are inversely
proportional. More information
