Mobile network operator SK Telecom plans to set the airwaves above its corner of the Pacific Rim ablaze with its latest announcement, heterogeneous wireless networks. Leveraging a combination of 3G, LTE and WiFi, the company is promising to deliver wireless speeds of up to 100Mbps to its customers. The network technology, which SK states is the "first of its kind," can provide downlink speeds that are equivalent to the sum of two independent networks. The carrier will be rolling out the 3G and WiFi portion of this network mashup (60Mbps theoretical maximum) during the second half of 2012, with LTE and WiFi (100Mbps theoretical maximum) coming in 2013.
