Rapid technical development of wireless cellular networks and the strong proliferation of hand-held mobile terminals among users on the one hand, and the development of the Internet technologies, on the other hand, have made evident the need to combine these technologies. In 1997, an industry-driven organization called WAP-Forum was established to develop technical standards that bridge the gap between the mobile telephone networks and the WWW world. The first versions (1.0) of Wireless Application Protocol (WAP) standards have been accepted by the Forum in April 1998 and the current versions (1.1) in June 1999. Versions 1.2 are now (12/1999) developed.Mobile terminals are small in size, have a relatively small memory and processor capacity and have small batteries. The wireless bandwidth in GSM and other similar second generation networks is also rather limited as compared to wire-line networks, ranging from 9.6 kbps to ca 170 kbps. In this paper we examine how much the byte codes used in the WAP environment can be compressed and whether the reduced transmission time of the application data warrants the increased memory and processor overhead caused by the compression and decompression.
