According to the latest forecast from ABI Research, LTE network deployments will continue to grow rapidly globally. Time-division duplex (TDD) network is picking up the pace and gaining more market traction. In Asia-Pacific, LTE-TDD networks will cover more than 53 per cent of the population by 2018 at a CAGR of 41.1 per cent between 2012 and 2018, while frequency-division duplex (FDD) networks will reach 49 per cent population coverage by the end of 2018.

"The increase of LTE-TDD population coverage is mainly driven by wide deployment in some Asian countries with large populations such as China, India and Japan," said Marina Lu, research associate at ABI Research. "Due to its complementarity of using unpaired spectrum, a number of LTE-FDD operators will expand their networks with LTE-TDD in additional spectrum to improve network capacity."

Among Asia-Pacific's recently completed, on-going, and upcoming 4G spectrum auctions, 25 per cent concern 2600MHz, 25 per cent 1800MHz, and 20 per cent 800MHz, which is consistent with the popularity of the 2600MHz band for LTE-TDD networks. "Asia-Pacific will be the region with the most LTE-TDD networks," added Jake Saunders, VP and practice director. "Of global LTE-TDD concluded contracts awarded to vendors so far, 47 per cent come from Asia-Pacific and the second largest portion of 18 per cent is contributed by the Middle East."

Considering spectrum efficiency, spectrum bandwidth, network capacity, etc., a number of operators are preparing to upgrade LTE networks to LTE-Advanced networks. In ABI Research's latest survey, there have been 29 LTE Advanced network commitments worldwide by 3Q13, of which 10 commitments come from Western Europe, 9 from Asia-Pacific and 5 from North America.
