SO WHAT IS 5G, ANYWAY?
5G means a lot of di erent things to di erent people in various industries. Every stakeholder in the game—vendors, mobile operators, 5GPPP, the ITU and others—has its own ideas and thoughts about what 5G should be, and there’s currently a split between two schools of thought. Evolutionary 5G is

an extension of current Long Term Evolution (LTE) and LTE-Advanced networks and is backward compatible with all 3GPP technologies. Revolutionary 5G, meanwhile, is a brand-new network architecture that requires a new air interface and radio access technology (RAT), moving away from current cellular designs.
5G is already on a path that goes beyond cellular, shaping up as a multilink architecture that enables direct device-to-device communications.
and wireless communications already coexist.
Still, there is simply no choice, as mmWaves are far from
being ready for prime time. So as a result, “real” 5G at higher spectrum bands isn’t expected until 2020.
USE CASES? WHAT USE CASES?

“PRE-5G”
Driven by the pre-5G race agenda spearheaded by Verizon, KT, SK Telecom, NTT DOCOMO, KDDI and So bank, all radio access network (RAN) vendors are developing 5G air interfaces and new RAT ahead of the release of spectrum. But these early 5G systems will be “pre-5G” and operating in sub-6GHz spectrum. And
let’s face it: there really isn’t anything new in sub-6GHz spectrum—it’s where existing mobile

that will not only provide humans with an enhanced broadband experience, but also address a wide range of industrial applications. What it
is not is a continuing development of 4G and current technologies. 5G is already on a path that goes beyond cellular, shaping up as a multilink architecture that enables direct device-to-device communications. 4G is just ramping up, and LTE as we know it is just at 3G transitional. As such, 4G will continue to evolve in parallel with the ongoing development of 5G.
is trying to nd convincing uses cases that can greatly bene t from the
proposed ITU IMT-2020 enhancements. And although the usual suspects are already in the game, companies such as Google and would- be entrepreneurs may come to the table with disruptive ideas.
Backing up the notion that industry will drive 5G, three-quarters of the global operators that participated in our recent 5G Strategies Global Service Provider Survey rated the Internet of ings (IoT) as the top use case for 5G. ■
