WiMAX (IEEE 802.16) is a last-mile broadband wireless technology for fixed and mobile wireless connectivity. The OPNET WiMAX specialized model is available for OPNET Modeler® Wireless Suite and OPNET Modeler® Wireless Suite for Defense. It supports the IEEE 802.16-2004 and IEEE 802.16e-2005 standards. It was developed by OPNET with guidance from prominent industry leaders such as Motorola, Samsung, Alcatel-Lucent, and France Telecom.

Network equipment manufacturers, telecom service providers, and defense organizations use the model to design WiMAX networks and devices. Studies include:

n Evaluating custom scheduling algorithms for WiMAX base and subscriber stations

n Optimizing application performance by leveraging WiMAX QoS policies

n Predicting network performance for different MAC and PHY layer profiles

n Visualizing live application performance over a simulated WiMAX network infrastructure
