A Proposal to Implement Mobile Wireless IP Telephony to the Mekong River Region

With the development of wireless LAN and VoIP technology, economical build-up of infrastructure in the rural areas of developing countries is now emerge in as a real possibility. In this milieu, we conducted an experiment at Thai National Mae Fah Luang University (MFLU) located in the outskirts of Chiang Rai in Northern Thailand, in collaboration with Thai Electronics and Computer Technology Center (NECTEC), where we verified the viability of mobile wireless IP telephony and WIPAS (wireless IP access system) developed by NTT. This paper reports on the demonstration experiment of FWA (fixed wireless access), and in addition, based on its results, examines the means of aligning WIPAS, wireless IP telephony and cellular network, and proposes the adoption of mobile wireless IP telephony in the rural areas of developing countries, which provides the mobility with the application of FMC (fixed mobile convergence)
