Abstract [en]

Wireless and Internet technologies are major driving forces in telecommunication today, which both have brought great changes to human life. The evolution of Personal Communication Systems (PCS) was expected to provide a mobile user with voice, data, and multi-media anytime & anywhere. During the past decades, GSM systems have been increasingly deployed worldwide, and GPRS and 3G as the successors of GSM have started to be delivered in some places, but with much lower speed than expected by the venders of communication systems and to the disappointment of investors. Fortunately, another wireless network – Wireless Local Area Networks (WLAN) are widespread in schools, shopping centers, hotels, and airports etc., so called hotspots. In contrast, with respect to bandwidth and coverage area, GSM, GPRS, UMTS are low speed Wireless Wide Area Networks (WWANs).

WLAN was expected to provide high-speed data, but within limited coverage area, while GSM provides voice service at anytime & anywhere, and GPRS provides low speed data anytime & anywhere. Hence, the integration of WLAN and GSM/GPRS is a very promising technology, which is an innovative method to improve the overall system efficiency and optimize the scarce resource of GSM/GPRS capacity. The aim of this Master’s Thesis is to study the integration of GSM/WLAN from different perspectives, including both business and technology. Because GSM had been deployed in most of world and WLAN hotspots are increasingly common, the study is very significant in practice today and in the near future. Based on the investigation and study, a prototype system was built, some implementation issues were investigated, and problems of further commercialization were examined.
