Abstract
Cordless telephone technology provides a long range and highly sophisticated wireless extension between a plurality of wireless piconet networks. In one embodiment, base units of separate cordless telephones include respective piconet front ends (e.g., Bluetooth protocol bearing RF front ends) in addition to the otherwise conventional RF front end. The piconet-capable base units are placed and made members of separate piconet networks, but within conventional cordless telephone range of one another, e.g., within one mile of one another. To allow communications between piconet devices on the separate wireless piconet networks, the cordless telephone base units pass piconet content information (i.e., the messages passed by a piconet device on a first piconet network including a first cordless telephone base unit intended for receipt by another piconet device on a second piconet network serviced by the other cordless telephone base unit. In another embodiment, a base unit of a cordless telephone is made a member of a first wireless piconet network while its remote handset is made a member of a second wireless base unit, and piconet content information is passed from a device on one wireless piconet network to another device on the other wireless piconet network over the wireless cordless telephone (e.g., 900 MHz or 2.4 GHz range) channel established between the cordless telephone base unit and its remote handset.
