Dual-Band Femtocell Traffic Balancing Over Licensed and Unlicensed Bands

Free registration required

Executive Summary

Many cellular User Equipments (UEs) today are able to access both the unlicensed band (e.g., via Wi-Fi) and the cellular licensed band. However, in most regions of the world, they are not allowed to access both bands simultaneously for data communications - users can only choose either Wi-Fi or cellular. In order to allow UEs to enjoy both bands at the same time, in the authors' earlier work a framework for femtocells to simultaneously access both licensed and unlicensed bands was proposed. In this paper, the framework is extended to include strategies for femtocells to balance their traffic in licensed and unlicensed bands.
