23.1 Introduction

The wireless cellular network has been one of the most successful communications technologies of the last three decades. The advent of smartphones and tablets over the past several years has resulted in an explosive growth of data traffic. With the proliferation of more smart terminals communicating with servers and each other via broadband wireless networks, numerous new applications have also emerged to take advantage of wireless connectivity.

As 4G LTE-Advanced [1, 2] networks mature and become a global commercial success, the research community is now increasingly looking at future 5G technologies, both in standardization bodies such as 3GPP and in research projects such as the EU's FP7 METIS [3]. ITU-R has recently finalized their work on the vision for 5G systems, which includes support for an explosive growth of data traffic, support for a massive number of machine-type communication (MTC) devices, and support for ultra-reliable and low-latency communications [4]. While today's commercial 4G LTE-Advanced networks are mostly deployed in legacy cellular bands from 600 MHz to 3.5 GHz, recent technological advances will allow 5G to utilize any spectrum opportunities below 100 GHz, including existing cellular bands, new bands below ...
