Cellular and Wi-Fi Integration

Summary

According to Cisco's forecast, mobile data traffic will grow to 30.6 exabytes per month by 2020, an increase by nearly 8-fold between 2015 and 2020 globally. This huge amount of mobile data traffic is putting a lot of pressure on the operators’ cellular networks. On the other hand, traditional network expansion methods, such as acquiring more spectrum and upgrading to more advanced communication technologies (e.g., LTE-Advanced), are costly and time-consuming. As a result, it is likely that the mobile traffic demand will exceed the network capacity in the short to medium term. An efficient way to increase the network capacity in a cost-effective and timely manner is to use complementary technologies, such as Wi-Fi or small cells, to offload the traffic originally targeted towards the cellular network. In fact, Cisco showed that the offloaded mobile data traffic exceeded the cellular traffic for the first time in 2015, where 51% of the total mobile data traffic was offloaded to the fixed network through Wi-Fi or femtocell networks.
 
The aim of this project is to design new technical algorithms and economic mechanisms to realize the full potential of future wireless networks with cellular and Wi-Fi integrations.
