ABSTRACT:
A system and method for avoiding interference between two communications system is disclosed. A preferred embodiment of the invention provides a method that obtains frequency information associated with a first RF link between a handset of a cordless telephone and a headset. Using the frequency information, the method then generates an RF channel for a second RF link between the handset and a base unit of the cordless telephone. The RF channel is different from one or more RF channels associated with the first RF link. Preferably, the headset is a Bluetooth headset. Preferably, the first RF link is a Bluetooth RF link. Preferably, the second RF link is a WDCT RF link.
