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.
