China Mobile and Huawei responded quickly to the "signal upgrade": 5G and 4G both increased by 12%

According to news on January 30, 11 departments including the Ministry of Industry and Information Technology jointly issued the "Notice on Carrying out the Special Action of "Signal Upgrade"", proposing that mobile network (4G and 5G) signals will be significantly enhanced. The end-to-end service perception of mobile users has been significantly improved.

China Mobile responded proactively and researched innovative solutions for efficient and low-cost 4G and 5G coverage in view of the difficult, long-term and high-cost problems of station construction in remote rural areas.

Recently, China Mobile Research Institute and Huawei completed field tests of 700MHz/900MHz dual-band dual-mode base stations in six cities including Tengchong, Chuxiong, and Lincang in Yunnan Province, verifying the product's ultra-long coverage capabilities and Hundreds of megabytes of business speed.

In this field trial in Yunnan Province, the 4G uplink rate of the dual-band base station can reach 32Mbps, and the downlink rate can reach 64Mbps; the 5G uplink rate can reach 139Mbps, and the downlink rate can reach 252Mbps; power dynamics between frequency bands After sharing is enabled, both the 5G experience and the 4G experience are improved by 12%.

The base station supports 5G and 4G co-sited, co-constructed and co-covered, which can significantly reduce network construction costs, promote efficient 5G and 4G signal coverage, and assist the rapid implementation of the national "signal upgrade" special action.

It is understood that China Mobile and Huawei have implemented a dual-band RRU with low intermodulation, high sensitivity, low power consumption, and high efficiency. On this basis, they have successfully developed and supported 5G and 4G standard 700MHz/900MHz dual-band dual-mode base station.

This dual-band dual-mode base station uses dual-band integrated power amplifiers to achieve dynamic sharing of power between frequency bands, thereby improving the 5G and 4G experience.

In addition, this innovative product can save up to 20% of construction and operation and maintenance costs, effectively reduce network construction and operation and maintenance investment, and provide a strong guarantee for China Mobile to accelerate network coverage in remote rural areas.
