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% of the population by 2018 at a compound annual growth rate (CAGR) of 41.1% between 2012 and 2018, while frequency-division duplex (FDD) networks will reach 49% 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,” comments 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% concern 2,600 MHz, 25% 1,800 MHz, and 20% 800 MHz, which is consistent with the popularity of the 2,600 MHz band for LTE-TDD networks. “Asia-Pacific will be the region with the most LTE-TDD networks,” adds Jake Saunders, VP and practice director. “Of global LTE-TDD concluded contracts awarded to vendors so far, 47% come from Asia-Pacific and the second largest portion of 18% 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 Q3 2013, of which 10 commitments come from Western Europe, 9 from Asia-Pacific, and 5 from North America.

ABI Research’s “Wireless Spectrum, Services, and Technology Deployment Tracker” aims to provide a comprehensive source of information about mobile network providers, their operating spectra, and network technologies globally. It covers seven geographical regions and includes a comprehensive list of all operational wireless networks along with their operating frequency bands and wireless technologies. Also included is a summary of the major network supplier contracts awarded, by geography, and network.  These findings are part of ABI Research’s Mobile Deployment Research Service
