The demand for wireless throughput has increased immensely, and high data rate wireless communications is of significance in emerging wireless local area networks (WLANs) and home multimedia networks. Massive data consumption being aided by emerging technologies is helping the demand for wireless throughput to experience exponential growth. Massive data consumption results from resulting from high-definition video streaming, automatic software updates, cloud backups, social media autoplay, and background app syncing. Meanwhile, the quantity of the available electromagnetic spectrum has never increased and or expanded. The total physical quantity of the electromagnetic spectrum is a fundamental physical constant covering an infinite, continuous range of frequencies and wavelengths. Nevertheless, the amount of the spectrum actively used or harnessed by human technology is rapidly increasing due to advancements in engineering, radio technology, and material science. Furthermore, wireless transmission in constrained environments such as a highly obstructed and large network environment is crucial. Thus, designing a very high-speed wireless link that offers good QoS (quality-of-service) and range capability in NLOS (Non-Line-of-Sight) environments constitutes a significant research and engineering challenge. MIMO (Multiple-Input Multiple-Output) enhances Non-Line-of-Sight (NLOS) communication by using multipath propagation to improve signal reliability, range, and throughput. The study investigates the multipath effect of MIMO system technology on QoS (quality of service) using unlicensed wireless frequency.
