Điện thoại 5G có đáng không?

chẳng đáng đâu,

ko nhanh hơn 4g là bao nhiêu, và cái nhanh nhất thì lại còn tùy thuộc vào mật độ đô thị nữa (hạn chế về tín hiệu), tình hình thực tế ngay tại hàn quốc đấy nhé

…Samsung, which makes both handsets as well as 5G network equipment, told investors on its own call that it expects its 5G business in South Korea to “shrink somewhat compared to last year.”

That last revelation is sobering. South Korea was the first market to deploy 5G services on a wide basis. Service launched in April 2019, but by year’s end consumers already were complaining that it didn’t live up to the hype (quảng cáo thổi phồng, cường điệu). Part of the problem is that services marketed under the 5G label can vary widely in terms of speed and availability. Some aren’t much faster than existing 4G networks. And the fastest—including those using millimeter wave technology—currently are available only in certain dense urban areas due to their signal limitations.

Meanwhile, 5G devices remain expensive. Samsung’s new 5G phones range in price from $999 to $1,399.
