Abstract
A wireless communications device that can support the communication of a data message via a selected one of multiple wireless data transport (WDT) technologies. A wireless communications device can support CDPD, control channel data transport technologies, such as the “CELLEMETRY” data communications service, and voice-channel modem operations by combining these WDT technologies within a single radio device. In the radio-to-base system direction, the appropriate WDT technology can be chosen based upon the data volume for the communication application. A control channel data transport technology can be used for very low volume; CDPD can be used for medium volume; and voice-channel modem operation can be used for large volume. The appropriate WDT technology can be automatically selected for use with the present data application to achieve an effective communication of the data content via the cellular system while also accomplishing a least cost distribution of the data content. The wireless communications device can be implemented by a single monolithic component for efficient manufacture and convenient use.
