China Mobile and TD-LTE Deployment

As spectrum becomes available around the world, operators are looking at 4G/LTE (Long Term Evolution) as the next major network upgrade to add capacity and lower operating costs.  LTE can be deployed in existing 2G or 3G bands, and in new spectrum such as 2.6 GHz now being allocated in many regions, and the Digital Dividend bands (700 or 800 MHz depending on region).

TDD LTE (also known as TD-LTE), transmits the uplink and downlink traffic within the same unpaired frequency band and is predominantly a mobile broadband technology. TDD LTE offers flexible and adaptable (real-time) uplink and downlink traffic ratio, which makes this technology suitable for asymmetric data applications such as HD video download and content upload.

TD-LTE can provide an effective upgrade path for existing technologies such as TD-SCDMA, TD-HSPA and WiMAX. China Mobile is one of the major proponents of TD-LTE.

China Mobile recently disclosed that it will invest $6.7 billion in TD-LTE this year.  The operator expects to end 2013 with more than 200,000 TD-LTE base stations in 13 cities, up from the 20,000 base stations deployed in 2012.

Huawei is a strategic partner with China Mobile, offering end to end TD-LTE solutions. It is positioned to showcase its solutions and ramp up volumes of its products and achieve economies of scale for this version of LTE.

ZTE is a Chinese multinational telecommunications equipment and systems company headquartered in Shenzhen, China known for competitive pricing, and steady growth. As of 2011 it is the second-largest Chinese telecoms equipment maker (after Huawei) and the world’s fourth-largest mobile phone manufacturer. ZTE’s core products are wireless, exchange, access, optical transmission and data telecommunications gear, mobile phones and telecommunications software.
