Data Offloading from LTE to Wi-Fi

Abstract

One of the alternate ways of solving the problems of mobile network congestion in a congested urban area such as at Tripoli University (Tripoli City –Libya) is the Wi-Fi offloading technique. This paper shows how Wi-Fi offloading will improve the efficiency of an entire mobile network using the Atoll simulation tool presenting options for the technical integration of Wi-Fi and cellular network. Moreover, it shows the challenges and future works of Wi-Fi offloading at Tripoli University. The different coverage, signal quality, capacity predictions, and simulations were carried out at Tripoli University. The simulation results showed that, after offloading a percentage of 4G data traffic to a Wi-Fi network, has improved the services of both voice and data. One of our main aims is to recommend that mobile operators take alternative ways to solve the current cellular congestions, many different studies demonstrated that Wi-Fi offloading can improve the signal quality and the network capacity by carrying part of data to Wi-Fi beams pointed toward users.
