5G: Frekuensi

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.

The 3GPP Release 15 of December, 2017 is the most common definition. Some prefer the more rigorous ITU IMT-2020 definition, which only includes the high-frequency bands for much higher speeds.

Other Considerations for 5G Frequency Bands

High 5G Frequency Bands

These bands are usually available and can be quickly cleared for 5G use.

Geographical Area 5G Frequency Band Europe 3400 – 3800 MHz (awarding trial licenses) China 3300 – 3600 MHz (ongoing trial) China 4400 – 4500 MHz China 4800 – 4990 MHz Japan 3600 – 4200 MHz Japan 4400 – 4900 MHz Korea 3400 – 3700 MHz USA 3100 – 3550 MHz USA 3700 – 4200 MHz

Very High 5G Frequency Bands (MMW)

These bands will allow the deployment of hotspots providing very high throughput thanks to the large bandwidth available for operators:

Geographical Area 5G Frequency Band Europe 24.25 – 27.5 GHz for commercial deployments from 2020 China Focusing on 24.25 – 27.5 GHz and 37 – 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 27.5 – 28.35 GHz and 37 – 40 GHz pre-commercial deployments in 2018

Lower 5G Frequency Bands (future considerations)

The bands 600 MHz, 700 MHz, 800 MHz, 900 MHz, 1.5 GHz, 2.1 GHz, 2.3 GHz and 2.6 GHz are considered for traditional coverage applications and new specific usages such as Internet of Things (IoT), Industry Automation, and Business Critical use cases. However “refarming” will be required for most of these bands, hence the time required to have them allocated to 5G will be much longer than the higher bands.
