Abstract
In this paper, we study the coverage and connectivity problem in wireless network on WiMAX (Worldwide Interoperability for Microwave Access) and WLAN (Wireless Local Area Network). Two Business networks have been simulated to connect two WLANs via a WiMAX connection, this will allow data to be sent and shared between the sites. Both technologies will be tested and compared to one another; to determine the optimal technology for long-term communication, and to understand how they can work together, and how they can increase the network efficiency and performance. This work has taken the advantages of OPNET Wireless modeler suites (OPNET 14.5) particularly the WiMAX and WLAN platform for our performance study.
