With the Long Term Evolution (LTE) standard continuing to develop, international differences in plannings and frequency allocation timetables have resulted in different frequency bands being used in different countries. TD-LTE standard\'s greater efficiency in terms of frequency spectrum usage has attracted the attention of carriers in a number of other countries.

21 TD-LTE commercial networks have been launched as of August, 2013, and 39 LTE TDD commercial networks are in progress or planned.

TD-LTE’s unique features have also played an important part in the technology’s growing stature in the market. Because TD-LTE makes asymmetrical use of unpaired spectrum, for both uplink and downlink, it is a spectral efficient technology. Spectrum is a valuable commodity for mobile operators, especially those who operate in countries where there is a limited amount of available FDD spectrum; or where only single unpaired frequency is available. Driven by its spectral efficiency, TD-LTE is now increasingly being viewed as an attractive proposition in markets.
