Roaming - Light Overlap

With RangeLAN2’s multi-channel architecture, Access Points
can be placed within the same cell area to increase the aggregate
throughput supported by the network. In addition, the overlap-
ping cells offer redundancy of coverage required in networks
where downtime is not tolerable.
