5G Radio Frequency
5th generation wireless systems, abbreviated 5G, are improved networks deploying in 2018 and later and may use existing 4G or newly specified 5G Frequency Bands to operate. The primary technologies include: Millimeter wave bands (26, 28, 38, and 60 GHz) are 5G and offer performance as high as 20 gigabits per second; Massive MIMO (Multiple Input Multiple Output – 64-256 antennas) offers performance “up to ten times current 4G networks;” “Low-band 5G” and “Mid-band 5G” use frequencies from 600 MHz to 6 GHz, especially 3.5-4.2 GHz.
This coming together of technologies, bandwidths, and applications to interact at varying high speeds.
It’s this coming together that is defined by global standard organizations.
5G NR uses two frequency ranges:
Frequency Range 1 (FR1), including sub-6 GHz frequency bands
Frequency Range 2 (FR2), including frequency bands in the mmWave range (24–100GHz)
5G Radio Frequency Country Specifications for mmWave bands
The chart below list 5G radio frequency spectrum as defined by country. Some countries use certain RF bands as they chart out their own country network needs and standards. Note: This chart is just stating what the mmWave bands are within countries allocated spectrum. There are other bands like the 60-64GHz band that is open for public use as defined by international standards and higher frequencies falling under the umbrella of 5G as they develop new applications to utilize this bandwidth and work within a 5G infrastructure.
Area Frequency Band
Europe 24.25 – 27.5 GHz for commercial deployments from 2020
China 24.25 – 27.5 GHz and 37.25 – 43.5 GHz studies
Japan 27.5 – 28.28 GHz trials planned from 2017 and potentially commercial deployments in 2020
Korea 26.5 – 29.5 GHz trials in 2018 and commercial deployments in 2019
USA 24.25 – 28.35 GHz and 37 – 40 GHz, 64 – 71GHz with pre-commercial deployments in 2018
India 24.5 – 29.5 GHz
License Free Spectrum
The FCC allocated an unprecedented 7GHz of un-channelized spectrum for license-free operation between 57-64GHz. This allows for anyone to create applications within this frequency to utilize this spectrum for their needs and applications.
One example is the common term “WiFi” that we all have grown up with. That term was a set of standards that defined what Wifi was and allowed for companies to create wireless routers, hubs and networks that gave us “WiFi”… now with the usage of 5G and millimeter waves, the IEEE again defined “WiGig”.
WiGig is a definition to use the 60GHz frequency space to carry information and have compatibility with current WiFi networks.
Now appliances, toasters, wireless TV streaming and more can (and do) utilize this frequency ti carry their high speed needs
