Essentials to Establish a Wireless Link
In order to establish a wireless link there are a few essential parameters that must be
configured properly. These setting must be configured correctly on both sides of the
link.
•
Transmit
Frequency
o
The transmit frequency in MHz is expected. The receive frequency is
automatically set based on the transmit frequency.
•
Transmit
Power
o
This is the maximum output power the unit will transmit.
•
Modulation and Channel_BW
o
The modulation and channel_bw are configured with the “speed”
command. The modulation and channel width need to match on both
sides of the link.
•
Default Opmode “ON”
o
Default Opmode must be on in order for the unit to transmit after a reboot.
•
Save
and
Reboot
o
The save is needed so that setting changes are persistent through a
reboot. A reboot is required for settings to take full effect.
If these parameters are met, and if the units are within range and properly aligned, the
wireless link will automatically establish itself and Ethernet traffic will begin to pass
between the radios. This is a list of MINIMUM requirements to establish a link.
Evaluate Link Quality
Link Test
A link test can only be performed on a link that is carrying traffic. Linktest can be used
even without the link lock, but it’s more meaningful when locked. The
linktest
can be
performed from the CLI only and will display information pertaining to link quality. Link
Test can be performed while carrying traffic without impacting customers. Link Test
only displays information for the local side of the link.
The fields displayed are LOCK, RSSI, MSE, BER, and TX.
