 Ministry of Industry and Information Technology approves 5G test frequency to be officially commercialized by 2020


It is understood that China Telecom has obtained a total of 3400 MHz-3500 MHz bandwidth of 100 MHz of 5G test frequency resources; China Mobile has obtained 2515 MHz-2675 MHz, 4800 MHz-4900 MHz bandwidth of 5G test frequency resources, of which 2515-2575 MHz, 2635-2675 MHz and 4800-4900 MHz bands are newly added bands, and 2575-2635 MHz band is the existing TD-LTE (4G) band of China Mobile. China Unicom has obtained 5G test frequency resources of 3500MHz-3600MHz bandwidth of 100MHz.

Experts pointed out that the frequency resources for issuing 5G system test frequency license were generally balanced. Give priority to the license of 5G intermediate frequency band test frequency with about 100MHz continuous bandwidth, which is conducive to giving full play to the technical advantages of 5G intermediate frequency band which takes into account both large capacity and continuous coverage. For telecommunication equipment, the use of different frequencies of telecommunication equipment in the radio frequency, channel are different. The development cycle takes 8 to 10 months for each frequency change. By issuing 5G test frequency, telecom operators and equipment providers can determine product development objectives, and greatly accelerate the process of product development in all sectors of the industrial chain. At present, the 5G spectrum allocation in other countries mainly adopts high, middle and low frequency band collocation. The high frequency band has short propagation radius and high transmission efficiency in densely populated areas, while the medium and low frequency bands have long propagation radius and better coverage. This time, the medium and low frequency bands are issued, and the allocation of high frequency bands is under consultation. At present, China Mobile is promoting 5G pilot projects in five cities and participating in the demonstration of 5G applications in 12 cities planned by the Development and Reform Commission. China Telecom has expanded the 5G innovation demonstration from the initial five pilot cities to 17 cities nationwide. China Unicom has also expanded the pilot scale to 16 cities. The third phase test of 5G launched by China 5G Propulsion Group in September this year is nearing the end, and the third phase test is the last stage before scale test and pre-commercial use. According to the plan, China will conduct 5G commercial trial in 2019 and officially commercial in 2020. Source: CCTV News Mobile Network Author: Sun Jiwei Responsible Editor: Ji Guojie_NBJ11143
