Original title: China Unicom: 5G Terminal White Paper (Phase 3)
<第三阶段><白皮书>Recently, China Unicom released the “5G Terminal White Paper” (hereinafter referred to as “white paper”). China Unicom expects to use the publication of the paper to present 5G terminal product requirements and key technical indicators for H2 2020 and beyond.
According to reports, the “White Paper” mainly stipulates the requirements of China Unicom's 5G terminals in terms of multi-mode multi-frequency, functionality, business, RF and protocol consistency, performance, machine card compatibility, and equipment management. It should be pointed out in particular that China Unicom did not include the N79 band in the NR band requirements for 5G terminals. According to the table given by China Unicom, there are mainly seven frequency bands: n78, n1, n41, n258, n3, n8, and n5. Among them, n78 and n41 are required bands.
The “n79” band caused some controversy some time ago. The main issue is the support of 5G applications and 5G terminals for this band's resources. Currently, only some terminals support the most 5G bands, and the vast majority of 5G terminals do not fully support the N79 and other bands, which has sparked discussions about “real or fake 5G.”
According to reports, the N79 band is the core high-frequency band. It is the highest frequency in the 5G band that operators can obtain. It has the advantages of large capacity and high speed, but its penetrability is poor. The n79 band can be used in limited space intensive communication scenarios such as shopping malls, subways, and large-scale gatherings, as well as private networks for applications in the electricity, transportation and other industries.
Currently, the 5G bands used by major domestic operators to build 5G networks are different. China Mobile has two major bands, n41 and n79, while China Unicom and China Telecom share the n78 band. China Radio and Television have the exclusive low frequency band and n79 band for radio and television.
China Mobile said that 5G base stations that currently support the N79 band are still in the testing stage. There are no recent plans to commercialize 5G in this band. For quite some time to come, the core of 5G band development will be the N41 band. Meanwhile, China Radio and Television, which also owns the n79 band, said it will cooperate with the power system to apply the n79 band to the industrial market, and will not open it to the general public market. Therefore, using a 5G terminal that does not support the N79 band will not affect the user's 5G experience.
