1. A method of transmitting data via a cellular telephone communication system comprising the steps of:
- a. transmitting fragments of a LAN MAC frame over a wireless link from a source computer to a Cell Controller, CC, the source computer being equipped with a cellular wireless modem for use in the wireless link;
b. transporting fragments of the LAN MAC frame from the CC to a Mobile Telephone Service Office, MTSO;
c. routing the fragments of the LAN MAC frame through the MTSO to a Mobile Data Service Controller MDSC; and
d. re-assembling the LAN MAC frame from successive fragments received at the MDSC.

Abstract
A method and apparatus is provided which permits mobile computers equipped with modems for cellular telephone systems to obtain various classes of data communication services, as well as voice service, including taking part in local-area networks. The LAN'"'"'s may be composed of conventional LANS in establishments or of other mobile computers. In this way, mobile computers can take part in mainstream client-server computing and also establish wireless LANs using the cellular telephone system.
