Mobile internet has rapidly evolved within the last decade. One can’t even imagine that there was a time before 3G not too long ago, when downloading the simplest of files on a mobile device could end up taking a lot of time. Much of the developed world has now become accustomed to 3G, 4G LTE in most cases, having up to 75 Mbps speeds on mobile devices. Though later this year it would be nothing compared to what South Korean carriers are up to. SK Telecom and LG Uplus are both expected to launch their 3band LTE-Advanced service later this year, offering subscribers speeds up to an eye-watering 300 Mbps.
This new service will be based on carrier aggregation, to achieve higher mobile internet speeds multiple bands are combined, SK Telecom has combined one 20 MHz bandwidth and two 10 MHz bandwidths, it is already conducting tests on this new service. LG Uplus, South Korea’s third largest carrier, has also gone down a similar road. This new service is set to offer speeds as high as 300 Mbps, almost four times faster than conventional LTE, and even faster than 150 Mbps LTE-Advanced and 225 Mbps wider-bandwidth LTE-Advanced. Both carriers are expected to launch this service later in 2014, while SK Telecom is already prepping up to showcase speeds of up to 450 Mbps at Mobile World Congress 2014 in Barcelona next month.
