It has been over a year since KT Chairman Hwang Chang Kyu’s declaration of his vision GiGAtopia on May 20, last year. The main idea of GiGAtopia was that the company would make both of its wired and wireless networks giga-class, through investment of KRW4.5 trillion for three years to come. We thought it would be a good time to check how they did for the past one year, and what innovation...

The current systems that we are using now, like 3GPP LTE or LTE-A, are commonly called 4G mobile communication systems. Then, what are 5G mobile communication systems? To discuss 5G, we should first look into what the mega trends in mobile services are these days. [M1. Traffic growth] The biggest trend would be soaring demands for multimedia and social network services witnessed recently. As...
This article was published in Korea Communication Review magazine (KCR Q1 2015). For the rest of the Q1 2015 issue of Korea Communication Review magazine please click here The 'giga Internet era' has just begun, finally offering speeds of 1 Gbps - 10 times faster than the 100Mbps. For the past 7 ~ 8 years, the maximum Internet speeds for all access networks (FTTH, LAN and XDS...

It features an in depth look at Carrier Ethernet 2.0 (CE 2.0) services,...
SK Broadband & SK Telecom (SK) introduced various gigabit Internet access network solutions at the World IT Show 2014 held in Busan on October 20th. SK noted that the new solutions will be able to provide a bidirectional Internet speed of 1 Gbps per user. The company has been offering Internet services including LAN, FTTH, HFC and XDSL to its 4.7 million subscribers. At the show, the compan...
2. Inter-cell Coordination Evolution Strategies CA improves network capacity by broadening frequency bandwidth, whereas inter-cell coordination technologies do the same task by enhancing frequency efficiency. Inter-cell coordination is designed to manage radio resources more efficiently by having cells in different sites share user and/or cell information with each other. Inter-cell coo...
SK Telecom is the #1 mobile operator in Korea, with sales of KRW 16.6 trillion (USD 15.3 billion) in 2013, and with 50.1% of a mobile mobile subscription market share in 2Q 2014. It launched LTE service back in July 2011, and now more than half of its subscribers are LTE service subscribers, with 55.8% of LTE penetration as of 2Q 2014. Due to LTE subscription growth, more advanced device feat...

Emergence of C-RAN (Separation of Baseband and Radio, and Baseband Centralization) Today, global LTE operators are competing with one another more fiercely than ever, under the pressure to provide better service quality and higher speed. Conventional Internet traffic has been increasing steadily. What's more, mobile traffic resulting from OTT video services, such as YouTube, Mobile IPT...
We will talk about LTE QoS this time. QoS functions provided by any network, whether wired or wireless, are all based on standards (IETF RFC, IEEE 802, 3GPP TS, etc.). They may work differently using different standards depending on whether the network is wired (Ethernet/IP/MPLS) or wireless (LTE/WiBro/Wi-Fi). But, basically what the QoS is about is that traffic quality is guaranteed (i) if...
