NTT DoCoMo had a pretty lavish setup here at CTIA, though no new product caught our eye. However, they did have the results from the Super 3G / LTE shenanigans they've been up to in Japan, and the results show serious speed. They're touting Super 3G / LTE as 3.9G -- wow, that extra .4G seems to be making a huge diff -- with theoretical downlink and uplink speeds listed as 70Mbps and 300Mbps. Compared to current HSPA speeds this is a monstrous leap, can you say kiss your cable goodbye? Hit the gallery below for more pics.
