Low Tx/Rx Power
The Tx/Rx power per chain is shown on the Client List page on the A5, or on the Dashboard of the C5. Although the
A5 transmits on 4 chains to optimize the signal, the C5 will only transmit and receive on a maximum of two chains.
Follow these troubleshooting steps if you observe low Tx/Rx power.
Low power on two chains
Consistent low power across both chains is likely due to long distance or EIRP limitations for selected channels. Use
the Mimosa Design application to model the link for comparison with actual performance. This will help determine if
the observed performance is expected, or if some other problem exists.
Potential solutions include the following:
Aim the antennas to achieve higher signal strength at each receiver
●
Increase Tx Power
●
Select a portion of spectrum that allows higher EIRP limits
●
Select a narrower channel width
●
Select a single channel instead of two channels
●
Install a higher gain antenna (A5c/C5c)
●
Relocate antennas to avoid permanent or temporary physical obstructions impairing the Fresnel zone
●
Low power on one chain
Clients connected to A5-14 may only use a single chain unless they receive strong signals from two of the four A5-
14 antenna panels which are pointed 90 degrees apart.
Clients connected to A5c with a single sector antenna have a better chance of connecting on two chains since all of
the energy is directed in one direction.
Potential solutions include the following:
Design networks where clients are closer in proximity to the AP.
●
Ensure that the client falls within the AP antenna pattern with adequate gain.
