LTE의 데이터 최대 속도는 1G

5G의 데이터 최대 속도는 20G ( DL 기준)

 

User 체감속도는 10배 차이나고 지연속도는 1ms 이내이다.

 

이 것이 사용자가 느끼는 가장 큰 차이이고

나머지는 통신 사업자가 느끼는 차이는 주파수, 그리고 속도 등이 있다.

 

LTE mobile technology has changed our lifestyles significantly with high data rates and low latency. With the diverse services and requirements demanded from today's mobile industry, however, LTE by itself is not capable of handling the necessary throughput, latency and reliability. Compared to LTE, 5G enables much higher data rates and ultra-low latency by using wide spectrum of high-frequency bands and advanced networking technology. 5G targets twenty times higher data rates and much shorter latency than LTE. As a result, more reliable transmissions and higher UE connection density will be possible in the 5G network. Key comparisons between 4G and 5G have been drawn
