The convergence of wireless applications presents a greater hope for consolidating e-Government (ICT-enabled or online government) applications even in resource-constrained countries such as those in Africa. This chapter presents an exploratory study that aims at discussing the extent as to how convergence of wireless technologies from different vendors promises to contribute to the consolidation of e-Government applications in Sub-Saharan-Africa (SSA). This is done by reviewing the different adoption stages of ICT and e-Government in SSA. It looks at challenges facing adoption of wireless technologies (GSMs, Wireless Internet Access, satellite transmission, etc.) across all the socio-economic value chains in SSA. The chapter looks at Botswana and South Africa as case studies by bringing out the different interventions that have been done in the realm of facilitating a conducive environment for the convergence of different wireless technologies. Out of the analysis of legal, regulatory, market and spectrum policies affecting the adoption of wireless communications in SSAs, the chapter draws out recommendations on how to consolidate wireless communications to be adopted in different socio-economic setups (e.g. e-government, e-Health, e-Banking, etc.).

Security and privacy protection are very strong requirements for the widespread deployment of wireless technologies for commercial applications. The primary aim of this chapter is to present an overview of the security and privacy issues by highlighting the need to secure access to wireless networks and the loss that might accrue from the breach of a network. The vulnerabilities of the IEEE 802.11 and Bluetooth networks are discussed, and a paradigm for secure wireless network is presented. The legal framework guiding the privacy issues in wireless communications is also presented.

Research and practices in electronic business (e-business) have witnessed an exponential growth in the last few years (Liautand & Hammond, 2001). Wireless technology has also evolved from simple analog products designed for business use to emerging radioactive, signal-based wireless communications (Shafi, 2001). The tremendous potential of mobile computing and e-business has created a new concept of mobile e-business or e-business over wireless devices (m-business).

There is no doubt that wireless communication technologies have been one of the most interesting innovation fields in the telecommunications industry in recent years. The spectacular rate of innovation in this field has enforced the vision of ubiquitous connectivity: the vision of a world where every human being and every electronic device, from high-end supercomputers to tiny sensors of temperature in your car, can talk to each other through a dense web of communication links. A vision of this kind, although more “human-centric,” is proposed, for example, in the “Book of Visions” (2001) published by the Wireless World Research Forum. Of course, wireless communication technologies are instrumental in accomplishing this vision, as we cannot possibly imagine to connect everything by means of cables. Moreover, wireless communications offer the advantage of supporting mobility even at high speed.
