CryptoGraf was invited to present our work at the Broadband and Wireless Workshop No.6 on "Mobile Communication and Application: Policy, Technology and Services". This series of workshops are under patronage of the Embassy of Japan, co-organized by Ministry of Internal Affairs and Communications (MIC) Japan, Japan International Cooperation Agency (JICA), National Institute of Information and Communication Technology (NICT) Japan, and National Electronics and Computer Technology Center (NECTEC) Thailand.

The Broadband and Wireless Workshops have been held five times on various issues related to ICT. This time, the workshop focus was on mobile communication and application. Mobile communication has become the most popular way of communication instead of fixed telephone lines.

These days, we observe the tendency of convergence in ICT services. Between fixed telephone and mobile phone, there is the trend of Fixed Mobile Convergence, FMC. Another convergence between mobile and digital TV has already started in Japan.

At the same time, we have to consider the problem on the mobile phone, such as risk of unsecured communication, spam mail, unhealthy usage by young generation, etc.

In this workshop, the situation and experiences on the development of mobile communication and its application, covering the aspects of policy and strategy to promote the development and use, technology, and service delivery, will be presented in order to improve knowledge of mobile communication and application, and to show the possibility of cutting-edge ICT.
