Multi-frequency multi-protocol wireless communication device
First Claim
1. A wireless communication device for allowing two-way communication of information including one or more of voice, data, graphics, or video signals in a cellular telephone communication system providing communication of such information in a particular format, standard, or protocol, said device comprising:
- operator input means and output means, respectively allowing an operator of said device to input said information and to receive such information via communication in said cellular telephone communication system;
a radio frequency (RF) transceiver for sending and receiving RF signals carrying said information in said cellular communication system;
an adaptation circuit conveying communication signals in said device between said RF transceiver and said operator input means and output means, said adaptation circuit including a first adaptation branch which comprises a first coder/decoder operable according to a first communication protocol, and a second adaptation branch which is different than said first adaptation branch and comprises a second coder/decoder operable according to a second communication protocol;
a first micro-controller selectively activating one of said first and second adaptation branches and detecting when a communication signal processed by one of said first and second adaptation branches in response to activation thereof results in a human-intelligible or machine-processable form, such that said first micro-controller thereafter maintains activation of said one adaptation branch to adapt said wireless communication device for communication of such information in the cellular telephone communication system.

Abstract
A wireless communication device may take the form of a cellular telephone, of a portable personal communication device, or even of a desk top personal computer which is equipped to communicate over the wireless cellular communication system in effect in a particular area. The wireless communication device is configured to self-adapt to various operating frequencies and communication protocols which may be present in the cellular communication environment so that the device is able to provide communications in several service areas even though the frequencies of operation and the communication protocols in use in the service areas may be incompatible with one another. The wireless communication device may also include facilities for transmitting and receiving video, graphics, and data files over an RF bandwidth. The various communication standards and protocols which may be used for these communications are recognized by the communication device, and it self-adapts to provide communications in the formats, standards, and operating frequencies which are available in particular cellular communication environments.
