ABSTRACT:
A system and method that increases the capacity of a wireless network using frequency diversity. A user switches between channels of a network using a single network interface card in such a manner that nodes desiring to communicate overlap while disjoint communications mostly do not overlap. A driver is inserted into a device's networking stack and controls the network interface card using a plurality of virtual wireless network adapters. Packets for a recipient are queued when the recipient is not accessible on the node's channel. In one embodiment where multiple nodes are switching in and out of channel, the method changes part of a nodes channel hopping schedule to ensure concurrent connectivity in a channel for at least a brief time period such that packets can be received/transmitted with desired nodes.
