Fast Technology reported on December 25 that recently, Anhui Telecom and Huawei completed 18ghz+2.The first commercial verification of the 1GHz dual-band 8T8R RRU.
2.1G opens 5G, 18G enables 4G, and 5G and 4G networks are enabled on the same device at the same time to achieve dual-band and dual-mode coverage.
Compared with traditional 4T4R base stations, 8T8R uses leading technologies such as high-gain arrays, precise beam scanning, and high-resolution airspace pairing, and achieves "wider coverage, better experience, and lower energy consumption" through multi-antenna beamforming.
Moreover, the industry's only true broadband power amplifier is used to achieve 18ghz and 2Millisecond-level power sharing between 1GHz frequency bands avoids wasted power allocation.
The test results show that compared with the traditional 4T, the 5G coverage is increased by 5dB, the average downlink rate is increased by 18%, and the average uplink rate is increased by 43%.4G coverage boosts 26db；The total flow in the demonstration line increased by 42%.
This means that high-speed rail users can get the best network experience regardless of whether they are connected to 5G or 4G.
Passengers can enjoy a variety of entertainment services such as smooth live broadcast, high definition, and new calls on the high-speed rail, and at the same time, they can also conveniently carry out important office services such as remote and remote work.
