devices, a tool such as Netstumbler (http://www.netstumbler.com/downloads/) can be used. A
spectrum analyzer can be used for further characterization of interference in the band.
1.5.1 Mesh channel selection
The mesh radio channel must be the same for all EnRoute500s in a given mesh cluster.
Adjacent mesh clusters will get a performance benefit if they are on different channels as the
clusters will not interfere with each other. The 802.11a channels that the EnRoute500 mesh
radio can be configured to use are all non-overlapping.
1.5.2 AP channel selection
The access point radio channels used by the EnRoute500s in a mesh cluster can differ. It is
advisable to use different access point channels for adjacent mesh nodes to reduce
interference.
However, it may be more important to select the access point channel based on the presence
of other 802.11 devices in the area rather than configuring it to be different than that of an
adjacent EnRoute500. A site survey should be conducted to determine which access point
channel will provide the best performance.
Some of the 802.11b/g channels that the EnRoute500 access point radio can be configured to
use are overlapping. Only channels 1, 6, and 11 are non-overlapping.
