引又唔敢引埋最後一句...

然而,Softbank 和本田也有類似合作車內 5G 測試,去年兩家公司就在北海道進行針對智慧型汽車的連網技術,所以這似乎並非唯一選擇。另外,日本各家電訊商其實都有分別與不同廠商合作進行 5G 測試,Softbank 自己早在 2016 年就有跟 Ericsson 來探索 5G 連網的技術、DoCoMo 則是與華為,而 KDDI 就剛在年初和三星進行 5G 測試。

其他嘢我唔講住,香討好似冇乜人知:

1. 蘋果嘅5G數據機IC(大陸叫集成基帶,或者簡稱基帶)係同第三方買,傳聞中蘋果自己嘅數據機IC,起碼後年先有機會見到。
2. 美國高通Snapdragon X50係全世界第一款5G數據機IC。
3. 美國自己除咗高通,仲有intel有出同類產品,大陸嘅展訊佢都有份㗎。
4. 第一家推出符合3GPP Release 15預商用標準嘅廠家係韓 ...

                Huawei Launch World’s First 5G Chipset and 5G CPE                        Huawei launched the world’s first 5G Chipset and first 5G CPE at MWC 2018 in Barcelona yesterday. According to Huawei official sayings, the 5G chipset model is Balong 5G01, which makes Huawei the first company offering an end-to-end 5G solution through its network, devices, and chipset-level capabilities.

As the world’s first commercial terminal device, Huawei 5G Router supports 3GPP 5G Standards with Huawei developed 5G chipset Balong 5G01, which it labeled as being the world’s first commercial 3GPP 5G chipset supporting download speeds of up to 2.3Gbps across sub-6GHz and millimeter-wave (mmWave) spectrum bands. The 5G CPE comes in a sub-6GHz model and an mmWave model, Huawei announced. This device marks a milestone as Huawei sets the stage for the next generation of wireless connectivity.


The HUAWEI 5G CPE has two models, low frequency (sub6GHz) 5G CPE and high frequency (mmWave) 5G CPE respectively. The HUAWEI low frequency 5G CPE is small and lightweight, compatible with 4G and 5G networks, and has proven measured download speeds of up to 2Gbps – 20 times that of 100Mbps fiber. This provides an ultra-fast experience, allowing users to enjoy VR video and gaming experiences, or download a TV show within a second. The HUAWEI high frequency 5G CPE is available in indoor and outdoor units.

“mmWave technology will be an important tool in ensuring widespread deployment of 5G technology in Canada. Huawei’s 5G solutions and terminals will enable 5G coverage over a neighbourhood or small community cost effectively, while providing more convenient and high-speed home broadband Internet access services.” said Dr. Wen Tong, Huawei Fellow, and CTO Huawei Wireless, “This friendly user trial will drive the global 3GPP unified 5G standard and build a solid foundation for the 5G early commercialization.”

5G technology will underpin the next leap forward for our intelligent world, where people, vehicles, homes and devices are fully connected, delivering new experiences, insights and capabilities,” said Richard Yu, CEO of Huawei Consumer Business Group. “Since 2009, Huawei has invested US$600 million in research and development into 5G technologies, where we have led the way with innovations around network architecture, spectrum usage, field verification and more. From connected vehicles and smart homes to AR/VR and hologram videos, we are committed to developing a mature 5G ecosystem so that consumers can benefit from a truly connected world that transforms the way we communicate and share.”

南韓 EXYNOS 5100 係 2018-08-15 RELEASE..
https://news.samsung.com/global/samsung-announces-exynos-modem-5100-industrys-first-5g-modem-fully-compliant-with-3gpp-standards

Exynos Modem 5100 to accelerate 5G commercialization with successful over-the-air 5G-NR data call

The new single-chip modem supports multi-mode communication, ensuring high efficiency in data transmission

The Exynos Modem 5100 supports both sub-6GHz and mmWave spectrums specified in 3GPP’s 5G standard

和華為既MODEM最主要見到既分別係MUTLI-MODE..
華為分開SUB-6G和mmWAVE兩個..
而三星就將佢合而為一..

以公布來計..
5G MODEM最早公布係華為,不過分BAND..

5G 同時支援雙頻既MODEM係三星...

追加三菱測試環境
10m 同 100範圍
要講技術嘅話,咁你知乜野係蜂窩狀網絡吓哇?
100米距離重要唔係一般圓形範圍
到底可唔可以用嚟起覆蓋全城嘅網絡呢……🤦🏿‍♂️
唔好咁多幻想啦,三菱同華為之間根本唔存在競爭關係
有關係都係合作

Ps. 同場追加美國at&t🤦🏿‍♂️😂超搞笑測試環境
https://www.thev ...
三菱電機係華為核心供應商之一..
華為主要係無線接入(mobile access network)..
而三菱電機有天線陣列,核心網絡(core network)光通信交換等等..

DOCOMO測試主要依靠華為5G平台..三菱電機負責車戴應用..兩者互相支援...


https://unwire.pro/2018/11/26/ntt-docomo-mitsubishi-5g-in-car/news/

5G 其中一個將會大派用場的地方,就是自動駕駛汽車的連接,屆時穩定而快速的網絡連接將會相當重要。最近 Docomo 就與三菱合作,創下連接速度的新紀錄。

日本最大電訊商 NTT Docomo 與三菱電子在神奈川縣的室外測試中,車載 5G 連線的速度達到了 27Gbps,是目前車載 5G 的最高速度紀錄。今次是首次有單一裝置在基站的 10 米距離內提供超過 20Gbps 的連接速度,而當汽車離基站 100 米的時候,速度亦有 25 Gbps。
NTT Docomo 原先計劃在 2020 年全面推出 5G 網絡服務,不過現在則以 2019 年為目標,希望趕及明年舉辦的欖球世界盃。高速的車載網絡,可以連接巴士或火車等運輸工具,為乘客提供快速上網服務。而未來的自動駕駛汽車也可以受惠於更高速的網絡。
除了 NTT Docomo 之外,Softbank 亦有與 Honda 合作在北海道進行測試,採用 Ericsson 的技術。至於 NTT Docomo 的器材則採用華為技術。

呢度又証明一樣嘢,中國的對手只有一個,叫"外國",當美國勁唔過中國時,D人就話韓國可以勁過中國,當韓國都唔得時,D人又會話日本勁過中國,當XX都唔得時,又會話另一個XX會勁過中國…唉…做中國真難… ...
中國唔難做,根本係根據自己所需去做..

難既係班反中人仕..年年喊中國崩潰,中國點衰點差..
點知中國失驚無神,嚇你一驚,
原來背後做左好多策略性既野..

如最初上海磁浮,好多人喊水魚,溫洲動車失事,即時話中國高鐵死硬..
新城初起,又話係鬼城,
但隔左數年,入晒伙,又冇媒體敢再報...

"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。"

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。
marketing為主的稿
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.

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

https://www.ednchina.com/news/201809201411.html ...
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...
