No Limit of Speed in 5G?


The first 5G tests were launched in Japan in 2014, in collaboration with NTT DocCoMo, Fujitsu, NEC, Samsung, Alcatel-Lucent, Ericsson and Nokia. The work was completed quickly and Qualcomm introduced the first 5G connection to the chip with a built-in chip (Snapdragon X50 5G). Qualcomm will launch its 5G phones in the first months of 2019. Various countries are rapidly completing their 5G infrastructure work. The selection of the frequency spectrum as a key step and the final stage of the technical specifications will be completed by the organizations responsible for the development of telecommunication standards in the summer of 2018. The first 5G NR (New Radio) standard paves the way for large-scale trials based on existing infrastructures for commercial expansions to take place in early 2019. For users, this new generation will provide a dozen times faster connection than the current 4G + series. 5G, beyond the very high resolution and information flow rate, will also provide great possibilities in areas such as driverless vehicles, virtual reality, augmented reality, robotics, smart home, smart industry, smart city. French Orange and Swedish Ericsson announced that they had reached a connection speed of 10 gigabits per second (Gb / s) in the preparation tests. In contrast, the current 4G + connections can only reach 200 megabits per second. The exceptional speeds achieved in 5G tests were achieved by the combined use of various technologies, such as centimetric waves or focused use of the radio. Fujitsu and Tokyo University of Technology also announced that they had reached a speed of 56 Gb / sec. Google has reached a speed up to 40 times 4G in the Skybender project. In addition, the consortium bağlantı Automotive Edge Computing ors established by Intel, Ericsson, Toyota, Denso and NTT DoCoMo successfully carried out a 5G connection test with a car speeding 30 km / h. In driverless vehicles, one of the areas where 5G will play an important role, the amount of data and data flow rate required for services offered to both passengers and passengers requires that the vehicle remains stable despite the movement. During the test, the Toyota Alphard was able to watch an ultra-HD 4K video at a speed of 30 km / h and 1 Gb / second sending and 600 Mb / sec reception speed. The consortium continues to research and identify the 5G standards by developing the necessary computer and network architectures in a joint effort with Audi, BMW, Daimler, Huawei, Nokia and Qualcomm under the 5G Automotive Association (5GAA). South Korea and Japan have announced that they will present the first full-scale trial with this new technology in the Winter Olympic Games in Pyeongchang with Intel's participation. Both operators and infrastructure providers, as well as the entire telecom industry, are testing the different technologies that will be used for 5G at the moment and form the global norms of the future. The main technical challenge was to design a transceiver chip that could modulate and demodulate these broadband signals in the frequency range of the millimeter wave without data loss. In order to achieve this, CMOS (Complementary Metal Oxide Semiconductor) type circuits were used in the production of the electronic chip which can separate and reassemble each signal to two different 10 GHz wide bands and transmit over different frequency ranges (72-82 GHz and 89-99 GHz). This method made it possible to increase the transmission capacity without reducing the quality of the signal.
