WiMAX, or IEEE 802.16, is a significant development in wireless digital communications that is primarily intended for "Metropolitan Area Networks". This technique increases broadband wireless connectivity up to 50 km for fixed stations and 5-15 km for mobile stations, much exceeding the range constraints of Wi-Fi-802.11 standards, which normally provide coverage within 30-100 meters. WiMAX, a cutting-edge solution recognized globally, has been ratified by the IEEE 802.16 group and is now operational in a number of regions. It can handle a wide range of applications, including next-generation cellular communications, personal area networks, local area networking, and digital broadcasting. This study looks at the integration of several antenna technologies, specifically MIMO systems, with different modulation schemes such as BPSK, QPSK, 8-QAM, and 16-QAM. The performance of various setups is evaluated in the presence of Additive White Gaussian Noise (AWGN), with an emphasis on the effect on bit error rate relative to signal-to-noise ratio. The findings demonstrate WiMAX robust capabilities as well as prospective wireless transmission advancements.
