바로..

Low-Band : 1Ghz 미만의 주파수대역(예를들어 600Mhz대역)

Mid-Band : 3~6Ghz 주파수대역(한국에서 사용하는 3.5Ghz 포함)

High-Band : 수십Ghz 주파수대역(mmWave라고 부르죠)

이렇게요

즉, Low-Band가 미국에는 추가되어 있습니다

하지만...

한국은 700Mhz대역도 방송국에 뺏겼으니........

============================================

Sub-6 5G referred to as:

• Verizon: “5G low-band network”

• AT&T: “AT&T’s 5G network”

• T-Mobile USA: “T-Mobile Nationwide 5G” or “T-Mobile’s 600MHz spectrum”

• Sprint: “Sprint’s True Mobile 5G”

mmWave 5G called:

• Verizon: “Ultra Wideband (MMW)” “mmWave” “UWB”

• AT&T: “AT&T’s 5G+ network”

• T-Mobile USA: “millimeter wave (mmWave) high-band spectrum”

• Sprint: N/A

Definitions:

• Low-band: Under 1 Ghz

• Mid-band: 3.6-6 Ghz (Under 6Ghz is Sub-6)

• High-band: 24-40 Ghz (Over 24Ghz is mmWave)
