"This week’s Qualcomm Snapdragon Technology Summit was supposed to be the coming-out party for blazing-fast 5G cellular networks — the first time that journalists would be able to see real, consumer 5G devices running on real 5G networks from Verizon and AT&T."
睇清楚" consumer 5G devices running on real 5G networks from Verizon and AT&T"🤦🏿♂️
5g devices, 5g networks, 重要加個"REAL" 字阿哥仔
重要呢單嘢係三星,愛立信,高通有份參與…
唔係細廠搞嘅嘢
NTT DoCoMo has announced attaining 5G speeds of 27Gbps during outdoor trials with Mitsubishi Electric in Kamakura, in Japan's Kanagawa Prefecture.
According to the Japanese carrier, this was the world's first 5G transmission to exceed a peak speed of 20Gbps using one terminal, with a communication distance of 10 metres attaining the 27Gbps speed, and a speed of 25Gbps over 100 metres.
NTT DoCoMo used the 28GHz millimetre-wave (mmWave) frequency band, massive-element antenna systems, and 16-beam spatial multiplexing technology with 500MHz bandwidth, which they said could be used to transmit high-speed connectivity to vehicles with multiple passengers such as trains and buses.
"Base-station antennas installed on the wall of a building directed beams to mobile-terminal antennas installed on the rooftop of a vehicle," the companies said, explaining that massive-element antenna systems technology allow for several data streams to be transmitted in parallel.
"The mobile terminal moved along two different streets. The distance of one mobile terminal was 10m from the base station and the distance for the other was 100m."
NTT DoCoMo has actively been working to push 5G capabilities, completing trials of 5G integrated access backhaul (IAB) technology with Chinese networking giant Huawei in May, which it said increases the wireless coverage of mmWave spectrum.
