South Korean operator SK Telecom has launched a platform that it says will provide real time information on what its customers are doing. The Context Platform uses data collected by a customer’s smartphone, if it is embedded with the platform, via its camera, GPS, sensors and wifi to discover contextual information about that subscriber.
The firm explained that the platform allows it to make informed guesses about whether the user is walking, for example, as the handset detects the user’s repeated movement and speed via its sensors and GPS. It then analyses the data it has collected through an algorithm to conclude that the user is “in a walking situation”. SK Telecom added that the more the platform repeats this process of analysis, the more accurate the platform becomes.
The operator said the platform can also make conclusions based on customers’ usage patterns involving social networking, voice calls, SMS and applications.

SK Telecom and LG Uplus, number one and three respectively in South Korea’s mobile market, both claimed a world first on developing three-band carrier aggregation (CA) for LTE-Advanced technology.
SK Telecom plans to demonstrate its triple-band CA technology at this year’s Mobile World Congress, but will be going one step further by aggregating together three lots of 20MHz. This, says SK Telecom, will give top-line speeds of up to 450Mb/s on LTE-Advanced.
According to GSMA Intelligence, South Korea is the world’s most advanced 4G market with penetration as a percentage of total connections passing the 50 per cent mark in Q4 2013. This compares to around a quarter 4G-user penetration in Japan and the US.
