When recently contemplating about the use of frequency bands for LTE in different parts of the world I realized that there have been different approaches: In the US, network operators opted for deploying LTE in the 700 MHz area and have only recently started to use higher bands such as the 1700/2100 MHz band for LTE services. In Europe most carriers started with the 1800/2600 MHz band but quickly also opted for the 800 MHz band to push nation wide coverage. When I was in China recently, I noticed that I could only trace deployments in the 1900+ MHz range (e.g. TDD bands 39-41 as described on Wikipedia) but nothing below that. In retrospect, I find it quite surprising that they haven't started their rollout on lower frequencies to get a large footprint in their not so small country.
