篇野係the verge個記者去參加Verizon 同AT&T
响Maui island，一個Hawaii 嘅島辦嘅商用5g網絡同設備實機演示會
設備係用三星同Motorola各自提供5g概念機，愛立信設發射基站
但係記者質疑個速度點解咁慢嘅時候
At&t同愛立信解釋話佢地唔係要做speed test
所以頻譜只係用左100Mhz, 到正式時會用400-800
Mhz,到正式速度唔一樣，所以唔係打算隱藏自己速度慢嘅咁喎
之但係個記者就好懷疑，個演示全場記者冇得
親身掂啲實機同試實際嘅hotspot，全程只係睇demo，又話用唔係正式頻譜，咁樣"real" 法，好難唔令人覺得有問題
所以標題第一句就係：The first ‘real world’ 5G test was a dud
Dud, 意思係啞彈，即係放左個屁
大致上係咁，返緊工睇睇唔到咁詳細🤦🏿♂️
篇野簡單英文唔係好難啫
Ps. 我又揾到另一篇野，關於Verizon即係上面提及嘅其中一間供應商，可以睇到比佢"正式" 到盡可以有幾快 http://wirelessone.news/mimo-2/1 ... th-800-mhz-spectrum
原來頻譜double 就真係速度都double 咁計喎
800Mhz即係佢演示嘅"驚人速度" 8倍左右啦
即係1.xGbps, 都重係好慢(佢自已內文都有寫)
"Speeds could be doubled from "300 to 1,000 megabits." Verizon could raise the top speed to 2 gigabits for consumers to outpace U.S. cablecos, now mostly at 1 gigabit"
第二段第一句，同推測相約，比佢有機會谷到盡都係2Gbps, 重要唔知係實際定理論值🤦🏿♂️
