2480 results about "Handset" patented technology

A handset is a component of a telephone that a user holds to the ear and mouth to receive audio through the receiver and speak to the remote party via the built-in transmitter. In earlier telephones the transmitter was mounted directly on the telephone itself, which was attached to a wall at a convenient height or affixed to a desk stand.

Wireless communication device with multiple external communication links

A decentralized asynchronous wireless communication system is disclosed for providing voice and data communication that allows flexibility of communication paths for local communication or for communication to external networks. The system makes use of communication docking bays that may communicate in a local mode with other communication docking bays or handsets within a same microcell via signal extenders. In an extended mode, a communication docking bay located in a first microcell of a first macrocell may communicate with a second communication docking bay or handset in a second microcell of the first macrocell via signal extenders and a network extender. In a remote mode, a communication docking bay located in a first microcell of a first macrocell may communicate with a second communication docking bay or handset in a second microcell of a second macrocell via signal extenders and network extenders. The communication docking bays also provide a communication path to a Public Switch Telephone Network and other communication medium. This feature provides an alternate means of connecting a mobile handset to a Public Switch Telephone Network without communicating through a network extender. The system is particularly suitable for operation in rural areas having a low population density.

Cordless RF range extension for wireless piconets

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.
