World 5G Communications Frequency Bands and Operation Modes

World 5G Communications Frequency Bands and Operation Modes

5G Communications Frequency Bands and Operation Modes

The frequencies used by each nation are gradually becoming clearer for full-scale deployment of 5G mobile communications, and can be divided broadly into two groups.

The first band defined*1 by 3GPP is from 450 MHz to 6000 MHz and is generally described as the sub-6 GHz band. It is used by the previous LTE/LTE-Advanced (LTE-A) and WLAN technologies, it suffers from relatively few technical issues, such as RF characteristics, and, depending on the selected frequency, has the advantage of making use of RF resources validated previously for 3G (W-CDMA) and 4G (LTE/LTE-A). One disadvantage is that an orderly wide frequency band cannot be secured because most frequencies are already in use.

The second band is from around 30 GHz to about 100 GHz*2; 3GPP defines the frequencies between 24250 MHz and 52600 MHz*1 called the millimeter band (mmWave) where a wideband can be assured because this frequency band is hardly used, offering the advantage of easy support for high-speed, large-capacity, data transmissions. One disadvantage is the large over-the-air (OTA) signal attenuation, presenting a number of technical issues that must be cleared due to the lack of actual usage by mobile operators.

As well as two frequency bands, there are also two operation modes: 1. The Non-Standalone (NSA) mode using a combination of a New Radio (NR) technology for 5G and LTE/LTE-A, and 2. The Standalone (SA) mode using a unique 5G NR technology where data is sent and received using control between base stations and mobile terminals (UE).

*2: Generally, mmWave is regarded as wavelengths from 1 to 10 mm and frequencies from 30 to 300 GHz, but current 5G communications include frequencies below 30 GHz, such as the 28-GHz band, and frequencies up to about 100 GHz as the upper limit.

National Frequency Bands and Operation Modes

According to national reports, 5G communications will be using different frequency bands and operation modes. In China, plans are proceeding to use the SA mode in the sub-6 GHz band. This will be the world’s first commercial deployment of 5G, and will implement Ultra-Reliable Low Latency Communication (URLLC) as one of the three key features*3 of 5G communications. We believe the intention is to connect industry, such as augmented reality (AR) using 5G.

Other countries consider several frequency bands and the operation mode for their early 5G service, and they are pushing forward with plans to use the NSA mode in the mmWave band. This prioritizes implementation of enhanced Mobile Broadband (eMBB) as one of the three key features of 5G; fixed broadband circuits will be used in the USA, while regions with high population densities, such as Japan and South Korea, are targeting improved data throughput.
