Speed of 1GHz reached in 2-kilometer test, could rise by 2020
While carriers around the world are still working on their 4G LTE network deployment plans, the next generation of cellular networks is being worked on by Samsung. The manufacturer has announced it has developed an adaptive array transceiver technology, which will apparently form the core of 5G networks by 2020.
Claimed to provide transmissions "several hundred times faster" than current 4G networks, the 5G technology is said to reach speeds of up to 1.056Gbps at a distance of up to two kilometers (1.24 miles), according to a company statement. The adaptive array transceiver uses 64 antenna elements transmitting in the millimeter-wave (mmWave) Ka band at a frequency of 28GHz in order to reach those speeds, which could reach several tens of Gbps per base station as it gets closer to public deployment.
A number of other parties are also interested in developing 5G or similar cellular networks. The "IMT-2020 (5G) Promotion Group" was formed by the Chinese government in February last year to work on the technology, with the European Commission also planning to invest 50 million euros ($64.81 million) this year to help with the development of 5G for a 2020 release. Various mobile companies have contributed around $56 million towards a 5G research center in the United Kingdom.
The South Korean government is said to have invested around $58 million in the technology's development in 2008, though it is not clear how much, if any, of this funding went towards Samsung.
