Preface
Global mobile traffic is expected to increase nearly tenfold by 2020 due to the increasing number of mobile-connected devices and the explosion of data-hungry mobile applications. Pushing traffic toward the network capacity quickly deteriorates the quality of service (QoS) perceived by users. Acquiring additional licensed spectrum to increase the capacity of Radio Access Networks (RANs) is increasingly expensive. Mobile operators are thus challenged by the revenue gap created by the exponential increase in mobile traffic not generating sufficient additional revenue to upgrade existing RANs. These circumstances have fostered an interest in cost-effective solutions to increase the capacity of RANs. Long-Term Evolution (LTE) in unlicensed bands (U-LTE) is among the promising solutions; however, since U-LTE is a nascent LTE technology, there are still various asso
