Abstract
This invention provides a method for improved frequency agility and preferably includes transmitting and receiving data on a primary channel; finding a secondary channel substantially free from interference during a period between data transmissions on the primary channel; and transmitting and receiving data on the secondary channel when an unacceptable level of interference is detected on the primary channel. In an alternate embodiment, data is preferably transmitted on a primary and a secondary channel during separate periods of a transmission interval. If an unacceptable level of interference is detected on either the primary or secondary channels, then the other channel is used for data transmission during one of the periods while another one of the periods is used to identify a new channel substantially free from interference to replace the bad channel.
