Mobile communication technologies include wireless broadband, 3G cellular networks, Near Field Communications whilst mobile devices such as 3G phones and Personal Digital Assistants (PDAs) now have the computing power equivalent to small laptops. Governments are considered candidates as mobile enterprises as they seek ways to interact with their constituents in a fast, efficient and effective manner, anywhere and in real time. However, these advances also present challenges, such as security, privacy and legal issues including theft and loss of these handheld devices, password cracking, data interception and viruses. This paper presents a modified model for realtime, ubiquitous Mobile Government adapted from the Stages of Growth Model and the Five (5) Stage Framework to take into account the rapid expansion and uptake of wireless technologies.
