Flexibility of spectrum deployment – A single band of up 20 MHz
can handle up and down traffic.
Spectrum costs – Securing FDD spectrum has had a premium over
Flexibility of deployment – LTE-TDD can be deployed as a
complete network solution, as a hybrid FDD/TDD LTE network, a backhaul
solution, or a network extension for a WiMAX network.
LTE-TDD will go mainstream in 2014, and it is not just about China
Mobile’s recently announced commitment to spend $3.3 billion on rolling
out 207,000 LTE-TDD base stations. In the US, Clearwire is anticipated
to have rolled out 5,000 LTE-TDD base stations which will play a
complementary role in Sprint’s overall LTE service plans. Around the
world, there are 60 LTE-TDD deployments, of which 21 have commercially
“As a result of this ramp up in LTE-TDD deployments, pops coverage has
surpassed 18.5% of the population by September 2013 and should eclipse
49% by 2018,” observed Jake Saunders, VP and practice director at ABI
Research. Keynote LTE-TDD commercial services are taking shape in Japan
(SoftBank), India (Airtel), Australia (Optus), etc.
Mobile carriers are sitting up and taking interest in LTE-TDD for a
number of reasons:
One of the key strengths of LTE-TDD is the cost of spectrum issued,
which has been 44% cheaper than LTE-FDD spectrum. Due to significant
contract awards in China, USA, Russia, and Japan, cost of LTE-TDD
equipment has effectively reached parity with LTE-FDD equipment. For a
stand-alone LTE-TDD vs. LTE-FDD network, Total Cost of Ownership is 13%
lower for a LTE-TDD network. In terms of backhaul, LTE-TDD can provide a
33% saving over Point-To-Point Microwave solutions and a 43% saving over
fiber. “LTE-TDD is attractive to carriers as a flexible and
cost-effective solution,” added Jake Saunders.
Telecoms infrastructure vendors are gearing up to supply the LTE-TDD
networks. ABI Research has conducted a Competitive Assessment of the
LTE-TDD suppliers in which Huawei came out top in the Innovation vs.
Implementation ranking, followed by NSN and Ericsson. All three vendors
have robust infrastructure solutions but Huawei’s success in securing
over 36 deployment contracts, strong IP holdings and R&D investment,
