4G mobile development strategy from recently announced in China

4G mobile development strategy from recently announced in China, it still uses the TD-LTE standard, while China Unicom and China Telecom have announced more widely used in the United States to adopt the FDD LTE standard. This and before the Telecom said may adopt the TD-LTE standard together with the move, even if it is not done TD-LTE, then at least to a mobile TD-LTE network rented in differ. But there is a hearsay to say, telecom may adopt the TD-LTE and FDD LTE hybrid network mode. Either way, the core of the problem boils down to whether Chinese 4G network used the unified standard of China, still the three largest operators according to their actual situation using the most suitable for their own standards? The advantages and disadvantages?

The first station in view of market competition, the author thinks that the three operators using different standards development 4G network should be more conducive to fair competition and. Just imagine, if the three operators have adopted the TD-LTE standard, because the mobile uses the TD-SCDMA standard in the era of the 3G, the 4G network construction, because the reason of its evolution, compared with China Unicom and telecom first of all to have a certain amount of first-mover advantage, or in the 4G competition, China Unicom and China Telecom quite lose at the starting line means, and it is not fair competition, but the relevant government departments mandatory standards for the implementation of the results of 4G.

Secondly, from the operator input costs, if the use of the unified TD-LTE standard, although for moving the 3G network to invest, but for China Unicom and China Telecom is the large-scale investment in new, technical difficulties do not say first, this is a great single input, drag, one of the main reasons for this why China Unicom and China Telecom will not in accordance with the development of TD-LTE standard 4G.

In fact, telecom and Unicom will not rush into the construction of 4G network. Because the two 3G network construction investment is enormous, not profit. For example, Unicom's 3G network has for 4 consecutive years to maintain the huge investment, capital spending last year amounted to 100000000000 yuan. Importantly, the 3G direction of upgrading technology of WCDMA correspond directly to FDD LTE, which can take the existing technology evolution route (GSM-WCDMA-LTE FDD), directly through the evolution of smoothing technique, the existing 3G base station upgrade to 4G. In this situation to push into the huge TD-LTE standards for them, not only lose the principle of fair competition, but also endless caused enormous cost pressure.
