Even though LTE is a global standard there are two different air interface flavors: The first one is FDD and pretty much destined to be used around the world. And then there is TDD, for the moment mostly foreseen to be used in China. However, many European operators have acquired TDD spectrum in the 2.1 GHz band during the 3G auctions back in 2000. So while I haven't heard anyone talking about this so far, I wonder if LTE TDD might be something of interest to European carriers!? In that regard, does anyone know if the TDD band in China is anywhere near the TDD region that was auctioned in Europe? Might be a great push for dual mode FDD and TDD devices.
