Interoperability of WiFi and WiMAX

The aim of this paper is to explore the two most popular wireless networks IEEE 802.11 and IEEE 802.16 with a view to examine the challenges and issues involved in the integration of both the networks. The 802.11 or Wireless Fidelity (WiFi) is a low cost wireless access technology that supports low data rate within a short range. On the contrary, the IEEE 802.16 or WiMAX (Worldwide Interoperability for Microwave Access or) is a costly network that support a data rate of 70Mbps within the range of 50km. To provide guaranteed and satisfactory service quality with moderate cost in wireless environment, integration of the two network technology is necessary. The difference in the MAC layer protocol and routing mechanism the interoperability of the two networks are challenging. In this paper, a brief discussion on WiFi and WiMAX issues are carried out, and investigated various methods and challenges for interoperation of WiFi and WiMAX technology.
