<strong>Smart</strong> Communications Quo vadis 5G? Quo Vadis 5G? The Long Wait Today’s IT industry is split between those who worry that it’s already too late to catch the 5G gravy train and those who think they still have plenty of time. This confusion is partly due to the mixed signals sent by the telco giants, but it is also due to the lack of a clear timetable for the rollout of next generation mobile technology. n By Bernd Schöne 42
Business and industry have been waiting for 5G to happen. Up to 100 bn devices are expected to be connected through the fifth generation of mobile communications, most of them via IoT. With 1,000 times the data capacity of today’s smartphone networks, the latency-free, tactile Internet promises a revolution, one which will be especially felt in the field of automation. In fact, “5G” is just a marketing term that covers a wide range of new mobile technologies. Back in early 2012, the standards committee of the International Telecommunication Union (ITU) – originally the International Telegraph Union – called for a network capacity of up to 20 gigabits. To put that in context: while LTE can theoretically achieve speeds of around 300 Mbps, in reality, we are not likely to get more than around 42 Mbps; standard 4G has real-world speeds of just around 14 Mbps. 5G trials are taking place today, with Verizon in the US, for example, demonstrating that its technology can achieve 30–50 times faster download speeds than currently possible with 4G. That would enable you to download a full movie in around 15 seconds, versus around 6 minutes on 4G. Most telcos and other providers are talking about 2020 as the likely date for commercial availability of 5G, but some seem intent on stealing a march on the competition. While Chinese manufacturer ZTE was the first handset manufacturer to showcase a 5G smartphone at GSMA Mobile World Congress in 2017, Lenovo has eyes set on 5G smartphone leadership, based on chipsets provided by Qualcomm, an American company. Has the future already begun? And will 5G really herald a new era, much like the introduction of the Internet itself more than a quarter of a century ago? One thing is clear: by using a much wider range of frequencies in a more flexible fashion, 5G has the potential Game changer 5G will have a huge impact on our everyday lives, from parcel deliveries to patient records and finding a lost dog or a space to park your car. to connect billions of mobile devices. Most of them will not be smartphones at all, but rather sensors and actuators included in a plethora of IoT devices, including automobiles, trains, and planes. Ready, set – go! Engineers are already busy building robots and entire production lines with connection capabilities that rival today’s fixed-line systems, only faster and more securely. 5G is the first mobile standard conceived expressly with machine-to-machine (M2M) applications in mind. Theoretically, at least, this could prove a gigantic shot in the arm for autonomous vehicles and other systems, including “smart factories.” For telcos and providers, the most important feature of 5G is its ability to adapt more flexibly than ever before to customer needs and demands. For that reason, 5G was conceived from the beginning as a software-defined network, or SDN; one which can M2M in Daily Life Fire department Beverage truck Doctor tracking patient records Connected fire alarm warns occupants Patient measuring blood pressure Parking spaces Fire alarm Parcel butler Customer waiting for parcel Delivery service photo ©: fts-hennig.de Dog owner Lost dog 43
