LTE and WiMAX sweeping like wildfire across the country, yet someone always has to come along and be a downer by showing off something even cooler. Those kids are the players at Korea's Electronics and Telecommunications Research Institute, the same folks who brought us a Body Area Network back in 2006 and this creepy looking koala. Now they're working on LTE-Advanced, the real true 4G that delivers 600Mbps downloads. That's six times what you can ever hope to expect from LTE and 40 times faster than 3G -- enough to download a 700MB file in 9.3 seconds or stream 3D HD footage on the go, a feat those crazy cats did in their rolling man cave shown above. Sadly we have no pictures of the thing on the outside, but we're seeing antennas. Lots of antennas.
