SK Telecom Launches HD Voice over LTE


SK Telecom launched an HD VoLTE service, initially featuring the Samsung Galaxy S3 LTE handset. Customers who already have the handset will be able to download a firmware upgrade later this month. The Galaxy Note 2 will also offer an HD VoLTE capability.
  • The premium HD voice service is available at no additional charge.
  • The HD voice connection uses 2.2 times the bandwidth of voice over 3G.
  • The HD voice call connection time ranges from less than 0.25 to 2.5 seconds. This compares with a mean call connection time of 5 seconds for 3G voice calls, and SK Telecom believes this difference will be apparent to the customer.
  • HD VoLTE carries a wide voice frequency range of 50 to 7000 hertz compared to a 3G voice call that typically covers 300 to 2400 hertz. The service uses Enhanced Variable Rate Codec (EVRC).
  • SK Telecom is using multi-carrier technology for the 800 MHz (20MHz) and 1.8 GHz (20MHz) frequency bands.

  • Last month, SK Telecom announced plans to commercialize LTE-Advanced in its network during 2013.

    SK Telecom, in collaboration with Qualcomm and Nokia Siemens Networks, recently tested a core LTE-Advanced technology called 'Enhanced Inter-Cell Interference Coordination (eICIC) that coordinates signal interference between macro and pico base stations. eICIC is gaining importance as more and more micro base stations are being built in traffic concentrated areas to accommodate explosive data traffic growth, thereby aggravating inter-cell interference.

    To demonstrate the technology, SK Telecom, Nokia Siemens Networks and Qualcomm created an environment where the strength of micro base station signals being transmitted to mobile devices was weaker than that of nearby macro base signals, resulting in signal interference. Then, they applied eICIC to prove that it can actually control the interference and stabilize data communications.

    The companies also succeeded in showing that the technology is capable of offloading data traffic by adjusting the coverage of micro base stations based on the level of data traffic concentration in macro and micro base stations. As commercial base station equipment has been used for the demonstration, the companies are expecting to achieve early commercialization of eICIC.

    SK Telecom noted that it now holds the record of demonstrating the three core technologies needed to usher in the era of LTE-Advanced: eICIC, Coordinated Multi-Point (CoMP) and Carrier Aggregation (CA). The company successfully demonstrated CoMP at Mobile World Congress (MWC) 2011 and CA at MWC 2012.

    CoMP is a technology that prevents base station interference and abrupt call disconnections in coverage boundary areas by enhancing signal strength, the lack of which leads to a significant drop in data transmission speed, and CA is a technology that provides twice or faster data rates by utilizing multiple frequency bands at the same time.

    SK Telecom expects to commercialize eICIC in the second half of 2013 to control signal interference and effectively offload data in downtown areas that experience heavy data traffic so as to provide customers with a mobile data service with greater speed and stability.

    The company commercialized CoMP, for the first time in the world, in January 2012, after adjusting the technology to suit the current LTE system, and plans to achieve early commercialization of CA in the second half of 2013.

    The operator will deliver LTE using both existing 800MHz frequency band (20MHz) and the 1.8GHz band (20MHz) it newly acquired last year. With an additional 20MHz uplink/downlink spectrum, it is now using a total of 40MHz for its LTE services. SK Telecom has launched a pilot service for multi-carrier in May 2012 and began full-fledged commercialization on July 1 to ensure a more stable and faster LTE service based on twice wider frequency bandwidth than its competitors. CA realizes data rates of up to 150Mbps by combining the speeds of 800MHz (75Mbps) and 1.8GHz (75Mbps) frequency bands.
  • In June, SK Telecom commercialized world's first LTE Femtocell to provide stable LTE call quality in underground, buildings and data traffic concentrated areas. With LTE Femtocell, customers can use high speed, premium quality LTE services anywhere, anytime.
  • In May 2012, Ericsson announced that SK Telecom, South Korea's largest operator, had signed a contract for LG-Ericsson to provide the LTE network including LTE RAN and Evolved Packet Core as well as support services including engineering, design, deployment and support services. The LTE radio access network will make use of Ericsson's Operation Support System for Radio & Core (OSS-RC) and RBS 6000 base stations. The contract, which covers commercial launch of LTE services in some of Korea's major cities - including Busan and Daegu, makes Ericsson one of the operator's main partners. Financial terms were not disclosed.
  • In January 2012, SK Telecom achieved the world's first commercialization of Advanced-SCAN (Smart Cloud Access Network), an upgraded version of SCAN, which has been developed to enhance LTE speed and coverage. Advanced-SCAN uses virtualization technology to ensure four times better call quality in base station boundary areas, thereby improving the overall LTE coverage and speed.

Google I/O Highlights Ambition as Premium Content Aggregator

 The Google I/O event in San Francisco drew a capacity crowd of app developers as the company updated its Android road map and rollout two key products.

Some highlights:

Google announced several Android milestones -- 400 million devices have been activated so far and there are now 1 million new activations per day.

The Google Play store is of strategic importance to the company. Google Play has just added TV shows and magazines. The Google Play catalog also includes thousands of movies, millions of apps, millions of songs, games and 4 million e-books. Google+ is building social networking tie-ins to this content, including with recommendation engines. The company continues to build partnership with content creators.

Google launched its Nexus 7 tablet, built by Asus and designed for Google Play. The tablet offers a 7” 1280x800 HD display, a Tegra-3 chipset with a quad-core CPU and 12-core GPU. The unit is optimized for Google applications, including Gmail and Google+ Hangouts. The units are Wi-Fi only (no 3G or LTE). The price is $199.

Google introduced the Nexus Q sphere -- an Android appliance that is all about social and cloud. The streaming device pulls content from Google Play for viewing/listening on home TVs and stereos. The New York Times reported that Google has chosen to manufacture this unit itself in California rather than outsourcing to Taiwan or China. The Nexus Q is priced at $299.

Google introduced Android 4.1 Jelly Bean, which will be released in July for certain Android smartphones and tablets. Key improvements include better syncing between devices; better message notifications; auto-resizable widgets; better predictive keyboard; offline voice typing; better search results using the Google "Knowledge Graph" and a new concept of search result cards; a new service called Google Now that delivers real-time information, such as traffic info, when the device knows that you are commuting; a better camera app that makes it easier to view and organize photos.

Google's Sergey Brin hosted a dramatic preview of Google Glass, the information eyeglasses project. Capturing and sharing real-time video will be a key feature. Developers will be able to purchase prototypes in early 2013. The company has not discussed product plans, specs or price points for a consumer product.

YouTube is releasing a new version of its Android app that pre-caches favorite channels, thereby avoiding buffering where possible

SK Telecom Plans VoLTE for Q3, LTE-Advanced in 2013

SK Telecom announced plans to support a high-quality VoLTE service in Q3 across Korea and to deliver up to 150Mbps data rates using LTE-Advanced in the second half of 2013. In a press conference earlier this week, Bae Joon-Dong, President of Network Operations Business of SK Telecom, said a new era of "LTE 2.0" will be marked by innovative services.



SK Telecom had 2.4 million LTE subscribers and a total base of more than 26 million mobile subscribers as of the end of April. This makes SK Telecom the second largest LTE service provider in the world after Verizon Wireless. The company expects to surpass 3.4 million LTE subscribers by the end of June in just a year since launching Korea's first LTE service in July 1, 2011. The company expects the number of cumulative LTE subscribers to exceed 7 million by the end of 2012.



Some highlights:



SK Telecom's LTE network covers 99% of the population. SK Telecom has been deploying LTE even in small towns and townships. It has already completed building LTE network in more than 84 major cities (plus railroads and highways), covering 95 percent of the population, in April 2012 through early execution of LTE network investment.



The company plans to introduce a Voice over LTE (VoLTE) and Rich Communication Suite (RCS) to be named "HD Voice" in the third quarter of this year. HD Voice is a premium communication service that offers voice, video and data in an integrated manner. Compared to the existing 3G voice call, it offers up to 2.2 times better sound quality and twice faster call connection speed (requires less than 0.3 ~ 2.5 seconds of call connecting time). HD Voice enables users to switch from a voice call to video any time during a call, and share content like photos and video with the person on the other end of the phone. The strength of HD Voices lies in that it can be further upgraded with the addition of new value and diverse features.



SK Telecom said it has employed state-of-the-art network technologies to ensure the best quality HD Voice service over LTE. In particular, the service will use QCI (QoS Class Identifier) technology to prioritize 'HD Voice' signals over other signals.



Although HD Voice is a premium version that offers differentiated value, the company plans to apply its current pay-per-second billing system to minimize customers' cost burden and promote service use. Details of service rates will be published later.



The RCS service enables integrated use of features like voice call, SMS, chatting, file-sharing through diverse networks and devices. The company will first integrate its messaging services such as SMS into an RCS service and provide differentiated service quality leveraging reliability and stability, the core strengths of mobile carriers, and plans to develop RCS into a next-generation integrated communication platform by expanding RCS-capable devices, securing fixed-mobile interworking, and converging RCS with HD Voice and other new services. The company plans to launch its RCS service in the second half of this year after building a detailed service structure and billing systems.



SK Telecom is preparing to release various lifestyle-enhancing services – in the areas of network games, mobile IPTV, etc. over its LTE network. The company is partnering with Korean game developers to optimized games over LTE (e.g. Genesis, Cart Rider Rush+, Blue Moon, etc.).



SK Telecom will also release a mobile IPTV service called 'Mobile B TV' in July. The service boasts high definition resolution at 1Mbps, which is the highest image quality realized for mobile IPTV service in Korea. Mobile B TV will provide around 40 channels including terrestrial broadcast channels, general programming and sports channels, and offer convenient features like reservation and notification.



SK Telecom will strengthen productivity-improving enterprise solutions specialized to run on LTE networks. Currently, the company is offering smart device-based customized enterprise solutions designed to suit the nature of each industry and company by leveraging the strength of LTE network.



In January 2012, SK Telecom achieved the world's first commercialization of Advanced-SCAN (Smart Cloud Access Network), an upgraded version of SCAN, which has been developed to enhance LTE speed and coverage. Advanced-SCAN uses virtualization technology to ensure four times better call quality in base station boundary areas, thereby improving the overall LTE coverage and speed.



SK Telecom commercialized world's first LTE Femtocell on June 1 to provide stable LTE call quality in underground, buildings and data traffic concentrated areas. With LTE Femtocell, customers can use high speed, premium quality LTE services anywhere, anytime.



SK Telecom's LTE network will be further upgraded with multi-carrier (MC), HIS (Hybrid Network Integrated Solution) and LTE-A. The MC technology will enable the company to utilize both its existing 800MHz frequency band and the 1.8GHz band it newly acquired in the second half of last year. With an additional 20MHz uplink/downlink spectrum, it will be using a total of 40MHz for its LTE services. SK Telecom began offering MC pilot service in the Gangnam Station area from May 30 and commercialization of MC will begin in July 2012, with plans to cover the whole Seoul area within 2012 and 23 other major cities by early 2013.



The company also said that it will achieve world's first commercialization of HIS that enables simultaneous use of LTE and Wi-Fi networks in the fourth quarter of this year. Hybrid Network provides data rates of up to 127 Mbps (LTE 75Mbps + Wi-Fi 52Mbps), which is 70 percent faster than that of current LTE network.



SK Telecom plans to commercialize Carrier Aggregation (CA), a core LTE-A technology that doubles data transmission speed by utilizing two different frequency bands, in the second half of 2013. CA realizes data rates of up to 150Mbps by combining the speeds of 800MHz (75Mbps) and 1.8GHz (75Mbps) frequency bands.



LTE customers are using around 1.7GB of data on average per month, which is approximately 60 percent more than that of 3G customers, which stands at 1GB. http://www.sktelecom.com
  • In May, Ericsson announced that SK Telecom, South Korea's largest operator, had signed a contract for LG-Ericsson to provide the LTE network including LTE RAN and Evolved Packet Core as well as support services including engineering, design, deployment and support services. The LTE radio access network will make use of Ericsson's Operation Support System for Radio & Core (OSS-RC) and RBS 6000 base stations. The contract, which covers commercial launch of LTE services in some of Korea's major cities - including Busan and Daegu, makes Ericsson one of the operator's main partners. Financial terms were not disclosed.

Compared to the existing 3G voice call, it offers up to 2.2 times better sound quality and twice faster call connection speed (requires less than 0.3 ~ 2.5 seconds of call connecting time). HD Voice enables users to switch from a voice call to video any time during a call, and share content like photos and video with the person on the other end of the phone. The strength of HD Voices lies in that it can be further upgraded with the addition of new value and diverse features.



SK Telecom said it has employed state-of-the-art network technologies to ensure the best quality HD Voice service over LTE. In particular, the service will use QCI (QoS Class Identifier) technology to prioritize 'HD Voice' signals over other signals.



Although HD Voice is a premium version that offers differentiated value, the company plans to apply its current pay-per-second billing system to minimize customers' cost burden and promote service use. Details of service rates will be published later.



The RCS service enables integrated use of features like voice call, SMS, chatting, file-sharing through diverse networks and devices. The company will first integrate its messaging services such as SMS into an RCS service and provide differentiated service quality leveraging reliability and stability, the core strengths of mobile carriers, and plans to develop RCS into a next-generation integrated communication platform by expanding RCS-capable devices, securing fixed-mobile interworking, and converging RCS with HD Voice and other new services. The company plans to launch its RCS service in the second half of this year after building a detailed service structure and billing systems.



SK Telecom is preparing to release various lifestyle-enhancing services – in the areas of network games, mobile IPTV, etc. over its LTE network. The company is partnering with Korean game developers to optimized games over LTE (e.g. Genesis, Cart Rider Rush+, Blue Moon, etc.).



SK Telecom will also release a mobile IPTV service called 'Mobile B TV' in July. The service boasts high definition resolution at 1Mbps, which is the highest image quality realized for mobile IPTV service in Korea. Mobile B TV will provide around 40 channels including terrestrial broadcast channels, general programming and sports channels, and offer convenient features like reservation and notification.



SK Telecom will strengthen productivity-improving enterprise solutions specialized to run on LTE networks. Currently, the company is offering smart device-based customized enterprise solutions designed to suit the nature of each industry and company by leveraging the strength of LTE network.



In January 2012, SK Telecom achieved the world's first commercialization of Advanced-SCAN (Smart Cloud Access Network), an upgraded version of SCAN, which has been developed to enhance LTE speed and coverage. Advanced-SCAN uses virtualization technology to ensure four times better call quality in base station boundary areas, thereby improving the overall LTE coverage and speed.



SK Telecom commercialized world's first LTE Femtocell on June 1 to provide stable LTE call quality in underground, buildings and data traffic concentrated areas. With LTE Femtocell, customers can use high speed, premium quality LTE services anywhere, anytime.



SK Telecom's LTE network will be further upgraded with multi-carrier (MC), HIS (Hybrid Network Integrated Solution) and LTE-A. The MC technology will enable the company to utilize both its existing 800MHz frequency band and the 1.8GHz band it newly acquired in the second half of last year. With an additional 20MHz uplink/downlink spectrum, it will be using a total of 40MHz for its LTE services. SK Telecom began offering MC pilot service in the Gangnam Station area from May 30 and commercialization of MC will begin in July 2012, with plans to cover the whole Seoul area within 2012 and 23 other major cities by early 2013.



The company also said that it will achieve world's first commercialization of HIS that enables simultaneous use of LTE and Wi-Fi networks in the fourth quarter of this year. Hybrid Network provides data rates of up to 127 Mbps (LTE 75Mbps + Wi-Fi 52Mbps), which is 70 percent faster than that of current LTE network.



SK Telecom plans to commercialize Carrier Aggregation (CA), a core LTE-A technology that doubles data transmission speed by utilizing two different frequency bands, in the second half of 2013. CA realizes data rates of up to 150Mbps by combining the speeds of 800MHz (75Mbps) and 1.8GHz (75Mbps) frequency bands.



LTE customers are using around 1.7GB of data on average per month, which is approximately 60 percent more than that of 3G customers, which stands at 1GB. http://www.sktelecom.com
  • In May, Ericsson announced that SK Telecom, South Korea's largest operator, had signed a contract for LG-Ericsson to provide the LTE network including LTE RAN and Evolved Packet Core as well as support services including engineering, design, deployment and support services. The LTE radio access network will make use of Ericsson's Operation Support System for Radio & Core (OSS-RC) and RBS 6000 base stations. The contract, which covers commercial launch of LTE services in some of Korea's major cities - including Busan and Daegu, makes Ericsson one of the operator's main partners. Financial terms were not disclosed.
