呢位師兄有follow. 唔知幾時可以真正批量測試,到時先清楚狀況。而家,隔塊玻璃都可能收唔到5G,呢D一般人未必知道
"去年,NTT Docomo在東京晴空塔上測試了華為5G終端,做到了1.2公里覆蓋、4.52Gbps的下行及1.55Gbps的上行速率,同時信號穿透玻璃的損耗僅為10dB。"
你要嘅玻璃穿透

用咁樣方法比較速度?各國網絡都唔同點比,而且at&t部機又唔係5g手機

"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

自卑的反面係自大!!
自己係甘,以為人地都係甘!!
你從大6落黎香港夠七年未,夠七年先可拎特區護照架!!
北方帝國人!!!!
真係唔好意思,踢爆咗你唔識字,淨係識殘廢字,不過都正常嘅,喺鄉下日日餵豬執豬屎,冇受教育機會,嚟到香港就將勤補拙喇,以後有乜嘢字唔識就請教一下老師

呢個測試其實無乜點,用架車黎收,又LOS,又唔係手機,又無多幾個UE。

窗,係講緊有uv鍍膜果種,文章唔清楚。

用500MHZ 達到27Gbps data...

https://www.zdnet.com/article/ntt-docomo-and-mitsubishi-electric-hit-27gbps-5g-speeds-in-car/

        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."

呢個應用係叫integrated access backhaul,可以用於現場廣播,如電視台直播賽事,
賽事專車一路跟住隊伍一路播(如馬拉松),
以前用微波,而家5G可以代替,頻寬更可支援8K多頻道直接送往廣播中心,再轉播全世界...
未來球賽亦可在場中安裝多個無線鏡頭,如用WIRE吊在空中,用5G送往球場主控中心,再轉播全世界...

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.

既然華為咁x勁,點解中國用左諾基亞?

係中移用落雞呀,唔係中國
中電信同聯通都係用華為

https://kknews.cc/tech/nb8np58.html

中移用諾基亞 有人咁講
升級原 諾基亞網絡 加 政治交易

一家獨大,未必係好事,同埋始終2G,3G NETWORK當年以諾基亞為主,
好多國家既4G都未做到50%覆蓋,建網一定要有BACKWARD COMPATITABLE,向下兼容..
而兼容既網正正好多係諾基亞網絡..

中移動用本身網絡,可以試驗混合諾基亞,華為,中興不同既3-5G組合,在轉換不同G既網絡上做到兼容,不斷線...
有利中興,華為爭取其他國家,由3G,4G諾基亞等網上,架設華為5G網絡...

係,但同一般用戶無關,要睇成本。
直播機會需要其實唔係太多,但奧運情況係有用

不過,5G多帶寬係好事,最緊要最後要平

謝謝。不過呢個只係1800MHz,難度有D唔同

話時話,手機都係4x4,一般用戶意義不大,用電會多
