Cell next generation networks will probably use a frequency range up to 71 GHz

The Federal Communications Commission (Federal Communications Commission, FCC) разрабатывает rules for dealing with high-frequency range, which can be used for the fifth generation mobile networks, 5G. As for 4G, in the US, these networks operate at frequencies from 700 MHz to 2 5 GHz where radio waves can pass through obstacles such as buildings and cover large distances. Yesterday, representatives of FCC voted for the rule to work with a frequency of 28 GHz, 37 GHz, 39 GHz, 64-71 GHz. The committee plans to hold an open debate on the use of the frequency range above 24 GHz.

According to FCC representatives, these frequencies can provide wireless data transmission rate of 1 Gbit / s to 10 Gbit / s. However, to ensure the normal operation of the network, with solutions such as restrictions on the range of data transmission and to overcome physical obstacles in the form of buildings, required a rather voluminous work that will take some time.

"Previously it was thought that the frequencies above 28 GHz can not be used by mobile operators, because the wavelength in this range is too small, and a radio signal can not overcome the need for network distances. But engineers are now turned this lack of dignity, finding ways to transfer this type of signal over long distances using special antennas. Now there are expectations that it will allow the transmission of data at higher speeds and fewer delays than those than the possibilities offered by modern mobile services now, "- said Mignon Cliburn, Acting Chairman of the Federal Communications Commission.

Also, there is little doubt that the 5G device will also support the work at frequencies below 1 GHz, Cliburn said. The use of both lower and upper bands of the spectrum will help operators to achieve higher data rates over long distances than it is now.

Current voting - not the last. Ahead - the authorization of the use of complex licensed, unlicensed and shared frequencies. Cellular data transfer can be combined with the satellite due to the proposed updates to the rules.

With regard to the telecom operators, then Verizon has already announced that it would like to see the 5G commercial deployment by 2017. This 4G, is likely to remain the norm for the next few years. Industrial group Next Generation Mobile Networks assumes 5G will not appear until 2020.

In the following, the FCC plans to hold an auction for the 600 MHz spectrum for LTE-networks. This will allow the company to expand 4G coverage networks to remote areas.
