Channel Setup
Multirate implementation

Bandwidth requirements factor into the coverage mappings, since the distance from an access point effects the available bandwidth. The example in Figure provides for seamless roaming, but not at a constant speed. This example takes advantage of multi-rate technology, to step down in bandwidth and gain greater coverage distances, with a single access point.

If 11 Mbps is required everywhere, the access points would need to be relocated, so that only the 11-Mbps circles are touching each other, with some overlap. This would require a greater number of APs, but consistent bandwidth would be achieved .
