LTE TDD to make up 25% of all LTE by 2016
Mobile operators like STC Saudi Arabia and Softbank Japan are going down the multi-mode LTE FDD/TDD route
Ovum has said that LTE TDD has gained wide acceptance from leading infrastructure and device vendors, and the research firm expects 25% of all LTE connections to include LTE TDD by 2016.
The research firm has said that the technology has already been adopted by operators in Japan, the Middle East and Europe. Daryl Schoolar, a principal analyst in Ovum's Network Infrastructure practice said: "The biggest market opportunities for LTE TDD will come from its deployment to support mobile broadband services. Other opportunities will include its use as a fixed wireless broadband network and for small cell backhaul."
Some other operators like STC (Saudi Arabia), Softbank (Japan), Optus (Australia) and Hi3G (Sweden and Denmark) have gone down the multimodal LTE FDD/TDD route, as part of upgrading current infrastructure that supports GSM WDCMA and HSPA networks.
Schoolar added: "Combining multiple standards such as GSM and WCDMA/HSPA and LTE FDD and/or TDD will grow the overall network capacity and increase quality of service. This is just a small part of it; the bigger opportunities lie in operators deploying it as their primary 4G network, such as Bharti Airtel in India and Mobily in Saudi Arabia. Moreover, LTE TDD provides cost benefits due to the price of unpaired spectrum, which can be passed on to end users."
Market estimates place the total commercial devices at over 60. The production volumes and choices are continuously increasing, and vendors like Huawei and others support multi-mode, multi-band devices.
"Thanks to multi-standard base stations, mobile operators will look to the same vendors that deployed their 2G/3G and LTE FDD networks to deploy their LTE TDD networks," concluded Schoolar.
