Japanese operator eAccess has announced that it has begun trialling a 4G LTE service in preparation for a launch in the country in March 2012. Meanwhile Telefonica’s UK arm, O2 has also launched a 4G trial in London. The operator will be using the trial to shape its plans for a commercial 4G rollout, following Ofcom’s 4G spectrum auction, which is expected to take place sometime in 2012.
