Development of 5G technology is very fast and everyone is trying to get ahead of 2020, which is a generally accepted term for launching the first commercial 5G networks. So far, advanced tests have been underway for launching pilot projects. One of them is the venture of Intel, Ericsson and Telia carrier. We have here an event that has been hailed as the first 5G network in Europe.
The next-generation cellular network, or just 5G, seems a very distant future. Most customers believe that operators should first refine their existing 4G LTE networks, which in practice run 10 times slower than advertised slogans. However, this is not true. In fact, LTE technology offers exactly as much as it assumes in theory. With the use of OFDMA (Orthogonal Frequency-Division Multiplexing Access) and SC-FDMA (Single-carrier FDMA) techniques, the data rate is the same as the theoretical. The only problem is that the maximum value which we see in ads is shared among all users of the same base station sector. This problem will disappear in 5G networks, where the capacity of a single cell will be so large that each customer will achieve satisfactory speed without difficulty. However, 5G networks are not only for ultra-fast mobile Internet.
Telia, Ericsson and Intel have unveiled a real-time 5G network.
5G is going to be 10 times better than 4G. This means that the new generation will provide cells with 10 Gbps capacity (4G capacity is defined at 1 Gbps) and packet delay is less than 1 ms (in LTE it is 10 ms). Therefore, 5G networks will find common applications in real time applications where response time is critical. One of such 5G networks will be launched in Tallinn and Stockholm as early as 2018. Intel (terminal), Ericsson (base station and core network) and Telia (operator) are working on this.
Recently launched pilot network on Tallink ship.
The term network is a misuse here. The Tallink test is currently being carried out in the Tallinn port. Internet connection on the Tallink Silja Europe ship is delivered via 5G technology. It is used by 2 000 passengers (of course they directly use Wi-Fi access point, which is connected over the 5G link), as well as on-board systems. But that’s not all. The most interesting application of this pilot 5G network is the ability to remotely control an industrial excavator. Sounds trivial, but in this case the operator uses an augmented reality based controller. This enables the excavator operator to be in a safe and comfortable office while the machine is operating in a hazardous environment.
