China mobile is willing to increase its confidence in the industry chain

As the spectrum of resources has been divided, a boulder has been removed from the commercial path of td-lte. In the "td-lte technology and spectrum symposium" held recently, the planning scheme of China's 2.6GHz spectrum was released, and the 2.5ghz band of 2,500-2690hz was all classified as TDD spectrum. The spectrum is determined, which gives a clear signal to the td-lte industry chain, which eliminates the concern that manufacturers are engaged in td-lte, which is a critical step in the commercialization of td-lte.

China mobile is not "disappointed"

In the LTE era, the world has struggled to find a single band that can be used uniformly, so the LTE spectrum is very fragmented, but the main frequency is 2.6 GHz. Previously, China mobile has clearly expressed its desire and confidence in the 2.6GHz spectrum resources.

In the GSMA gathering to be held in Shanghai in June this year, China mobile chairman xi guohua has made it clear that "on the issue of the td-scdma LTE frequency, 2.6 G is itu determine the frequency of global frequency, frequency is also more abundant. In all cities where the procurement of tenders is expanded, China mobile will be deployed with 2.6 G. Other top mobile executives are also on different occasions, expressing the hope that the 2.6GHz will be used for td-lte.

Now 2.6 GHz frequency spectrum, the 2500-2690 hz all the ranks of TDD as many as 190 MHZ band resources, "although all these spectrum may not to move, but for the mobile, it is very good result", the German telecoms consultancy, China senior adviser Tan Yan says.

Several td-lte seems to be a foregone conclusion

In the view of several industry insiders, td-lte's 190M spectrum resources are "luxurious" if they are all used by mobile one, so the possibility of multiple operators pushing td-lte is extremely high.

"The 2.6GHz frequency band is a high frequency band with poor penetration and will increase the cost of network coverage. Will low frequency spectrum resources should be allocated to the td-scdma LTE, the frequencies, such as PHS use such TD - LTE frequency resource is very rich, such as the stage, probably two operators together to push the td-scdma LTE, even three together push the possibility of existence ", Tan Yanming said. He said the combination of low frequency bands and high frequency bands is beneficial to the construction and coverage of td-lte networks. "indoor 2.6GHz frequency coverage and low frequency coverage of outdoor Spaces are available."

Horizon research consultancy group Ceng Tao telecom, senior analyst also believes that if the radio and television networks, the possibility of the combination is more, two or even three carriers are more likely to push the td-scdma LTE together, "especially mobile co-opted radio and television networks, both complement each other, better than the complementary between mobile and railcom, and 700 MHZ band now belongs to the department of radio, film and television."

To inject a "strong heart" into the industrial chain.

Spectrum division determine, not only is good news for China mobile, the whole industry chain to promote td-scdma LTE mature also has a huge role, "it's arm," Tan Yan says, spectrum related to enterprise's r&d division will affect the industry chain and confidence.

The technical gap between td-lte and FDD is not obvious, but on the division of spectrum resources, td-lte is clearly at a global disadvantage. Now, the European Union, the United States and Japan allocate most of the spectrum resources to FDD, and TDD has very few resources. Such situation seriously affects the equipment business and the terminal manufacturer's investment in TDD development. China's clear division of td-lte spectrum and the bandwidth of 190M have undoubtedly enhanced the confidence of the whole industry chain.

In an interview with the media, Ericsson China chief marketing officer chang gang also said that the recognition of the spectrum was significant, and that both systems and end vendors could be more targeted for their preparations.
