IEEE 802.11 is the WLAN standard for providing moderate to high speed data communication in a short range generally within a building. IEEE 802.16 (WiMAX) is the standard for broadband WMANs that provide the Internet access over a long range in outdoor environments. However, it is susceptible to fading inside buildings. By integrating WLAN and WiMAX, the authors would be able to acquire the best of both these technologies. Ultimately, WiMAX based wireless networks would bestow backhaul support for WLAN mobile hotspots. Therefore, the service availability for mobile Internet users will expand through the extended WLAN coverage range. In this paper, an integration model is proposed by introducing an Integration Management Entity (IME) which maps the different traffic categories at the Customer Premises Equipments (CPEs).
