Interference analysis of LTE and Wi-Fi systems / Amir Hazwan Azman

Mobile broadband has transformed the way people access and share information. Basically, mobile broadband is used for communications, education, health care, and public safety. These will result in an exponential growth in the number of wireless subscribers. Consequently, the mobile broadband traffic has increased significantly over the last years and will continue to do so for many years to come. To satisfy the increasing demand, mobile operators will have to increase the capacity of their networks. However, the operating frequency of LTE and Wi-Fi is so close that can interference to occur. Hence, in this project, we design an interference analysis to find out realistic distance between the LTE transmitter and Wi Fi receiver. We consider a scenario where the LTE transmitter is located together with a Wi-Fi system in very close proximity. We evaluate and analyze the performance due to the separation distances between the two systems in terms of transmission power, capacity and the signal strength. Simulations results have shown that at 40 km distance, there is no interference between the transmission system.
