The explosive growth of the Internet over the last decade has led to an increasing demand for highspeed, ubiquitous Internet access. Broadband Wireless technologies are increasingly gaining popularity by the successful global deployment of the Wireless Personal Area Networks (Bluetooth- IEEE 802.15.1), Wireless Local Area Networks (WiFi- IEEE 802.11n), and Wireless Metropolitan Area Networks (WiMAX-IEEE 802.16). New ICT and e-Learning strategies and advances in Wireless standards and technologies-particularly in the areas of Bluetooth, WiFi (Wireless Fidelity), WiMAX (Worldwide Interoperability for Microwave Access) and mobile computing can help to bridge the digital divide in education and research. Using open broadband Wireless technologies and implementing mobile computing architectures, one can overcome the challenges of ground, infrastructure, and finance to increase access; deploy broadband quickly and cost-effectively to areas currently not served; and extend the benefits of digital revolution to previously unreachable populations. These technologies aim to provide low-cost, high-performance Wireless access to residential and business applications. As technology evolves to address portable and mobile applications, the required features and performance of the system will increase. Evolution toward the phase called "full mobility" provides incremental support for low latency, low packet loss and real-time handoff of subscriber terminals operating at high speeds. This paper presents the analogy of promising Wireless technologies on different frequencies: Bluetooth, WiFi, and WiMAX. This paper is organised into four parts: part I describes the functionality and usage of Bluetooth in the Wireless Personal Area Networks, part II presents the WiFi- IEEE 802.11n strategies for users considering higher-bandwidth alternatives to existing Wireless Personal Area Networks, part III discusses how the WiMAX is used as a current standard for Wireless data transmission technology, which is optimized to deliver high, bursty data rates to mobile subscribers, and to support real-time multimedia and Voice over IP (VoIP) applications, and part-IV explores how these emerging Wireless technologies differ from one another.
