5G private network is one of the important modes to develop the application of 5G industry. Through the use of special frequency, the construction of 5G private network in enterprises can better serve the application of the industry. At present, some countries have planned the frequency of private networks, and many enterprises have applied for the construction of 5G private networks and carried out business applications.
5G private networks will first be explored in the United States, Germany, Japan and other countries with relatively developed manufacturing industries. Since 2019, these countries have gradually opened the Sub-6 and millimeter-wave bands to all industries to apply for licenses for 5G private network frequency bands, which has promoted 5G application practice in manufacturing, transportation and logistics, scientific research, mining, oil and gas and other industries. For example, the German government provided 100M vertical industry-specific spectrum resources in the 3.7GHz band in 2019; Japan opened up dedicated spectrum for businesses in 2019; Last year, Brazil’s National telecommunications Agency (Anatel) passed three laws to establish LTE and 5G private networks by approving the use conditions and operation requirements of radio frequency bands for private networks.
The development of 5G private networks in some European countries
Germany is an early supporter of the development of 5G private networks. In November 2019, German regulators issued policies to plan 3.7-3.8GHz frequencies for 5G private networks, followed by 24.25-27.5GHz millimeter wave 5G private networks in 2021. So far the German regulator has issued 250 frequency licences. Citing a survey of 553 companies, German digital association Bitkom said 26 percent of German industrial companies want or have set up local 5G private networks, with 7 percent planning to do so themselves and 19 percent through their operators. Bitkom said 85 percent of companies that are deploying or plan to deploy 5G private networks will use 5G networks to connect their production plants, and 79 percent will use 5G for machinery control. Bitkom said 74 percent of respondents saw potential applications of 5G private networks for remote control, and 71 percent considered using them for AR and VR. Sixty-five percent of respondents are likely to use 5G for autonomous vehicles and transportation systems. Forty percent of companies want or have already used 5G for mobile robots.
With the growing demand for 5G private networks in the French industrial sector, the regulator has launched a three-year trial for a 100 MHz local private network license in the 3.8-4.0 GHz band, in addition to planning for the 2.57-2.62GHz band. The regulator has also penciled in 26GHz spectrum, which it recently granted to SNCF, the French national rail company. SNCF has partnered with operators Orange and Nokia to expand its industrial 5G test platform at Rennes railway station in northwestern France. The 5G private network provides access services to all passengers and is also used for railway maintenance. In addition, Orange and Nokia have deployed a 5G private network in the 3.8-4.0GHz band at the Schneider Electric plant in Normandy, which is mainly used for real-time data interaction of machines, production lines and the entire factory, as well as remote control of robots.
3. United Kingdom
According to the UK regulator, 1,600 licences have been issued since the shared-frequency access licensing scheme was launched in 2019, with around 20-70 new licences being issued each month. There are currently around 500 licences in the 3.8-4.2GHz band. The regulator said recently that the UK is optimizing the licensing and approval process to meet the growing demand for 5G private networks.
In November 2021, the Swedish regulator set aside 40MHz in the 3.5GHz band for 5G private networks, with simple management measures and very low frequency usage charges. Sweden has yet to see significant use of the spectrum. Recently, there has been an increase in usage in the healthcare and mining industries, which already have Wifi-based solutions and are now working on solutions based on mobile communications technology. At the same time, the Swedish regulator is also planning an 850MHz frequency in the 26GHz band, which is in less demand. Since the band is open to all users and the barriers to entry are low, Swedish operators are actively involved in promoting the deployment of 5G private networks.
5. The development of 5G private networks in Japan and South Korea
As of mid-August 2022, more than 100 companies in Japan have introduced 5G private networks, while fewer than five in South Korea. Most of the operators planning to build 5G private networks in Japan only use sub-6GHz, and the government is carrying out a practical verification plan to use 5G private networks as a solution to continue to expand the application of 5G private networks. According to DIGITIMES Research, most of the Korean companies that have been licensed to build 5G private networks are in sub-6GHz and millimeter wave (mmWave) frequency bands. The Korean government has encouraged them to use MMwave frequencies at a lower rate than sub-6GHz. It can be seen that the two countries’ official emphasis on 5G private networks is different
Although Japan is about a year behind Korea in switching to 5G mobile communication service providers in the 3.5GHz band, it is earlier than Korea in the opening of 5G millimeter wave service and the application for 5G private network by official enterprises. At present, the practical verification plan for 5G private networks in Japan is mainly sub-6GHz (4.7GHz), regardless of whether the private sector or the government has put forward it.
In order to expand the application range of millimeter wave frequency band (28GHz), the Japanese government’s 5G private network practicality verification plan is mainly applied in personal safety related fields such as railway and road, disaster prevention and mitigation, medical treatment and health care, mainly because these fields need to transfer Ultra High Definition at a higher rate; UHD) image to improve security.
In South Korea, after Naver Cloud, a subsidiary of network giant Naver, obtained the official license to build a 5G private network at the end of 2021, LG CNS (LG Consulting & Solutions), SK Networks Service (SK Networks Service), and Nable Communications (Nable Communications) will also receive licenses in 2022. In addition, CJ OliveNetworks has applied, and four of the five Korean companies will use both sub-6GHz and millimeter wave frequency bands.
