Abstract
This paper outlines emerging business models of heterogeneous wireless networks that are mainly Wi-Fi centric. Wi-Fi networks can be integrated with the Internet and cellular infrastructures to offer innovative services (data and voice) to individuals and businesses. In the metro area network or a “hot city” type of coverage, an integration of WiMAX and Wi-Fi technologies will provide the most cost-effective solution of backhaul and access, for both voice and data services. In the cellular arena, as mobile operators look for new ways to connect, Wi-Fi can easily be integrated with the existing mobile data networks (2.5 G/3 G). An integrated offering that combines the mobility of cellular and the speed of Wi-Fi is an ideal mix for mobile broadband subscribers. This article also analyzes how Wi-Fi technology is being complementary to other wireless technologies, leading to an expansion of an organized Wi-Fi ecosystem. From an integration standpoint, this article shows the importance of Wi-Fi for cellular operators and also shows how Wi-Fi is crucial for WiMAX technology to evolve, till the mobile version of WiMAX becomes a reality. Finally, the paper describes why regulators and policy makers should seek suitable strategies to promote or encourage Wi-Fi as an alternative broadband access technology.
