When we talk about 5G, there is one phrase that everyone agrees and likes to say – 5G will not only enhance speeds, but also have every thing ‘connected’ and every industry ‘converged’. What underlies all of this 'keeping every thing connected' is IoT while what keeps industries converged is artificial intelligence (AI) that analyzes big data and derives in...

작년 MWC에서 5G 기술이 첫 선을 보이면서, 5G 시연은 수 Gbps급 속도를 가능하게 하는 무선 기술 위주였다. 올해는 무선 기술이 더 발전하여 ITU-R이 권고하는 5G 최고 속도 20 Gbps급 시연이 있었고, 이 외에도 무선 기술을 이용한 응용과 새로운 망/플랫폼 특성, E2E 특성 등 5G 시연이 한결 다양해졌다. 이제 MWC에서 5G는 더 이상 속도 경쟁이 아니라 생활 변혁 경쟁으로 넘어갈 것으로 보인다. 아직 표준도 없는 "5G"란 용어가 이렇듯 익숙해진 이유는, 단순히 영상을 더 선명하게 끊김없이 본다는데서 벗어나 우리 일상과 산업이 새롭게 바뀐다는 기대와 긴장감 때문일 것이다. 다가올 생활 변혁을 기대하며, 우리나라 대표적인 네트워크/통신 기업인 삼성의 올 MWC 시연을 살펴...

Netmanias interview with China Mobile at MWCS 2015: 4G evolution (LTE-Advanced, 4.5G) technologies Part 1. LTE-Advanced ► Part 2. 4.5G (TDD+) 4.5G (TDD Evolution, TDD+) China Mobile also introduced some TDD+ (also known as TDD evolution), which can be called "not quite 5G yet, but 4.5G" technologies, in cooperation with Huawei. The figure below shows the concept of 4.5G, along...

In the past two years, some new technologies have been introduced in Korea, apparently increasing broadband Internet speeds 3~5 times faster, from 100 Mbps to 300~500 Mbps, instantly. It certainly is fascinating in that such speed improvement was achieved without the hassle of re-cabling construction in apartment buildings. Because 100 Mbps had seemed unbeatable for almost a decade, this sure w...

Enhanced Inter-Cell Interference Coordination (eICIC) As noted in the previous post about ICIC, we will find out about enhanced Inter-Cell Interference Coordination (eICIC), an interference control technology in LTE-A in this post. In LTE/LTE-A, one key challenge for operators is that they have to increase network capacity to keep up with fast-growing traffic. Especially, crowded areas in m...

Last week (March 27, 2013), KT, No. 1 telecommunications company in Korea with annual revenue of $22.3 billion in 2012, has entered into an agreement with Akamai, the world's No. 1 CDN service provider with annual revenue of $1.37 billion in 2012, for using Akamai's Managed CDN services. Since 2012, world's leading CDN service providers including Akamai, Limelight, Edgecast, etc. ha...

오늘은 LTE QoS에 대해서 설명드리도록 하겠습니다. 유선통신망이던 무선통신망이던 모두 표준(IETF RFC, IEEE 802, 3GPP, NWG등)에 기반한 QoS 기능을 제공합니다. 통신 방식(유선 Ethernet/IP/MPLS, 무선 LTE/WiBro/Wi-Fi)에 따라 그 표준과 방식의 차이점은 있겠으나 QoS는 결국 (1) 돈을 많이낸 가입자의 트래픽은 그 품질을 보장해 주겠다. (2) 중요한 서비스 트래픽은 그 품질을 보장해 주겠다(Voice나 Video 트래픽은 Internet 트래픽보다 소중하니까...). 입니다. 사실 (1)번은 그리 일반적이지 않을 것 같구요(우리가 통신사업자에 서비스 가입할때 돈 많이 내면 QoS 보장해 주겠다는 상품은 없잖아요). 보통 통신사업자는...

DHCP(Dynamic Host Configuration Protocol) 기술의 네 번째 문서로 DHCP 서버와 클라이언트 기능을 모두 지원하는 DHCP Proxy Agent를 통하여 단말이 IP 주소를 할당(임대), IP 주소 임대기간을 연장 그리고 IP 주소를 반납하는 절차를 설명하고 그 과정에서 DHCP Proxy Agent에 의해 변경되는 DHCP 메시지 파라미터들에 대해서 살펴본다. 또한 DHCP Proxy Agent의 DHCP 보안 기능에 대해서 소개한다. 목차 1. 개요 2. DHCP Proxy Agent 소개 3. DHCP Proxy Agent를 통한 DHCP 동작 원리 4...

사용자의 요청에 대해 웹 서버가 자동적으로 특정 페이지를 제공하는 것이 Redirection 기술이다. 본 문서는 Redirection 기술의 두 번째 문서로, Redirection을 위한 응답 코드인 HTTP 302 Found를 사용하지 않고, 정상적인 HTTP 200 OK 응답 메시지를 이용하는 기술에 대해 설명한다. 이는 Meta Refresh 태그를 포함한 HTML 데이터를 HTTP 200 OK 메시지에 전송함으로써 가능하게 하는데, 그 원리와 동작에 대해 살펴보고자 한다. 목차 1. 개요 2. HTML Meta 태그 3. Meta Refresh를 이용한 HTTP Redirection...
