The aim of the Portable Wireless LAN trial programme by JANET, under which this work is being carried out, is twofold. Firstly, we needed to develop a portable and easily carried Wireless LAN (WLAN) kit that should be able to provide local and global connectivity to the devices individuals carry for an academic study or module outdoors. In simple terms, the portable WLAN kit should provide local connectivity to devices around it, in the form of a 802.11b/g wireless network, and global connectivity with the aid of a backhaul connectivity option, such as a Satellite, 3G/UMTS or WiMAX link or by establishing its own connection to the Internet if that is feasible. Secondly, the project needed to study the backhaul connectivity options that could be utilized in the above context, so that we could identify and evaluate the suitability and applicability of the backhaul connectivity options that the Portable WLAN kit could utilize to establish a connection over. This report fulfills the second aim of the project and studies theoretically and practically three possible backhaul connectivity options, namely Cellular networks, Satellite Communications and WiMAX network, in an effort to give an insight of their characteristics and applicability for the goal of this project.
