The demand to provide global coverage for voice and the need to support data of different types—including two-way messaging, fax, graphics, and video—anywhere and anytime, is giving rise to the emergence of an array of digital wireless technologies, some that include a galaxy of low-Earth-orbit satellites. This chapter provides a survey and a brief overview of the wireless technologies, identifying those that provide data capability so that the CDPD technology’s merits and drawbacks can be discussed within the wireless framework.

The VSELP coding is known to distort music and also is problematic for dualtone multifrequency (DTMF) response systems like voice mail, fax, and remote control answering machines. DTMF tone generators can be installed at the MTSO to circumvent this problem. Vocoder distortion also obstructs the use of modems over the digital voice channels. Because the IS-54B does not define data services, no standards exist to provide data service over digital cellular. However, infrastructure equipment manufacturers have implemented proprietary protocols to transmit fax and data over digital cellular systems.

8 Kbps), making CDPD an attractive choice for “fast” responses and data transfers. Since the CDPD protocol is designed to mesh seamlessly with the existing IPbased networks, it can be used as transport for LAN-based wireless applications.
