While you guys in the United States have a whole range of LTE Android devices to choose from, in the UK we're still a long way from the point of getting LTE at all. An on-going trial being run in Cornwall by BT and Everything Everywhere (Orange UK and T-Mobile) is now set to extend until Summer 2012.
Rival network O2 is currently trialling the technology in London, but this scheme is aimed more towards proving high speed broadband is possible in more remote areas. Currently users involved in the trial are seeing average download speeds of 7 Mbps. While this may not sound overly impressive, it's faster than some fixed broadband connections in these parts of the UK.
The overall importance lies in the technology though. According to Ofcom, the regulator for communications industries in the UK, we aren't to expect widespread LTE on these shores until 2015 with an initial rollout beginning throughout 2013/14. Whether it arrives at all depends on the required spectrum auction, which has already been postponed until 2013. Looks like we're in for a long wait but at least the networks are still committed to developing the technology before we get to that point.
