5G 통신의 성능 지표는? | 16 e) 대비 초고속, 저지연, 초연결을 목표로 한다. 5G 통신은 최대 20 Gbps의 전송속도, 100 Mbps의 이용자 체감 전송 속도, 1 ms의 전송 지연, 10 6 기기 수/km 2 의 최대 기기 연결 수 등의 성능지표를 핵심으로 한다. 위의 성능을 달성하기 위해 Millimeter-wave (mmWave), Massive MIMO, 그리고 빔 포밍 등이 5G 통신의 핵심 기술로 떠오르고 있다. | |
5G 통신의 목표는 무엇인가? | IMT-2020 혹은 5G NR로 명명된 5G 통신은 기존 4G 통신 (IMT-Advanced or LTE-Advanced or IEEE 802.16 m) 및 3G (IMT-2000 or LTE or IEEE 802.16 e) 대비 초고속, 저지연, 초연결을 목표로 한다. 5G 통신은 최대 20 Gbps의 전송속도, 100 Mbps의 이용자 체감 전송 속도, 1 ms의 전송 지연, 10 6 기기 수/km 2 의 최대 기기 연결 수 등의 성능지표를 핵심으로 한다. | |
4G 안테나 사이의 공간을 최대화 하는것이 중요한 이유는? | 1/4 파장 inverted F type 안테나 (IFA 안테나) 및 inverted L type 안테나는 상대적으로 작은 크기로 인해 이동 단말기에 널리 사용되어 왔다 [6] . 4G MIMO의 경우, 높은 통신 속도를 얻기 위해서는 다수개의 안테나 단품이 요구되며, 안테나 단품들 사이의 충분한 이격 배치가 요구된다 [7] . 결과적으로 인접한 4G 안테나 사이의 공간을 최대화 하는 것은 스마트 폰에 가장 널리 사용되는 안테나 배치 전략 중 하나다. |
