A simple implementation to roaming between GPRS and WiFi Networks

Roaming between networks of different protocols and structures is one of the common situations, especially with the advances in the Internet technology, and the available services that users need to constantly access for their daily life. In this paper, we present the development of a software solution that is deployed to permit a seamless roaming between the two wireless network protocols 802.11b (WiFi), a wireless local area network, which is increasingly being used in homes and offices, and GPRS, a wireless wide area network which works as a data extension to the GSM mobile phone network. The solution is implemented and tested in hardware. The proposed solution tested for several applications demonstrates a reduction on network error swapping and shows higher performance.
