China 4G Network approaching great fusion era

The New Year's snow did not cover up the 2012 communications industry also raised doubts.

At the beginning of 2013, the domestic operator 4G Operation license issued by the news, the industry speculation will be released in May World Telecom Day, this day for the communications industry has a special significance, usually the industry events will be released in this period, there is speculation will be in October, this is the communication industry exhibition activities of the gold schedule, And be able to issue a license for the licence to leave a little more time to prepare.

These guesses invariably set the licensing time at 2013 years, while there is a more sensitive and controversial proposition, like icebergs under the sea, undercurrent, elusive, and more impactful.

What kind of 4G operating licences will be awarded to China Mobile, Chinese telecom and Unicom.

Although the industry has almost agreed that the WCDMA evolution of China Unicom to FDD LTE is a logical thing, td-lte China Mobile has become a foregone conclusion. China Mobile, in particular, is eager to work on LTE, which in the past two years has launched several rounds of tenders for td-lte equipment, and has opened a network of experiments in more than 10 cities in China.

But even so, the 4G license plate guessing mystery or in the river of suspense tapered, the industry in addition to several operators and 4G standard back and forth to do radish and pit collocation, still did not give a convincing answer.

The doubts about the Spectrum layout format

October 14, 2012, Dubai. At the Td-lte Technology and Spectrum Symposium, the Chinese government officially unveiled the 2.6GHz full TDD Spectrum planning program, and the Radio administration said it had decided to plan the 2500-2690hz of the 2,6ghz band and all 190MHz frequency resources as TDD spectrum.

The news came as the industry was in uproar. Spectrum is the carrier to carry out the 4G operation of the air territory, not enough spectrum is not operational at all, but the 190M spectrum is really shocking! The industry understands that such a wide spectrum, if only China Mobile one operation is incomparable luxury, because this spectrum is enough for three operators.

Td-lte In addition to China Mobile, there must be other operators to adopt, most likely is China Telecom, or a little bit of China Unicom is also a part. In shock, the industry's inertial thinking must come to this conclusion. For a time the industry is divided into two factions, TDD faction is flying, FDD faction depressed.

A week later, October 25, Beijing. At the press conference on the development of the industrial communications industry, MIIT announced the planned 2G and 3G frequencies, which defined the unassigned 2x60mhz and total 120MHz spectrum in the 1800MHz and 2100MHz bands for FDD frequencies.

Thunder reappears, and the industry's TDD and FDD have also seen a big reversal of the expected expression. The 120M FDD LTE spectrum is also wide and plentiful, and is enough for three operators to use. This time the spectrum released, let China Unicom overjoyed, China Unicom is the most natural FDD users. Another surprise is that the spectral division will be very advantageous to the low frequency band is classified as FDD, the low-frequency segment in the subsequent construction of the network process, will have a good penetration and coverage effect.

Two division The spectrum of both FDD and TDD is plentiful, and TDD and FDD have raised a big question in addition to realizing that the telecommunications authority has turned its hands on the cloud as a means of rain. Is it to make the two standards go hand in hand, to develop together, or to generate several carriers to share the frequency bands? In addition, which faction will China Telecom be pulled into?

The prelude to the fusion of chip competition

December 17, 2012, Beijing. The industry will never think of a seemingly ordinary tender will make the chip industry chain collective feel the deep sting.

China Mobile's first Td-lte terminal product bidding, a total of nearly 10 chips in the competition, but Qualcomm a 40% of the market share, the remaining number of the winning proportion is not high, sequace Occupy 4 terminal chips, Huawei's HiSilicon for three Td-lte terminal chip providers, The remaining Td-lte terminal chip providers, including ZTE Microelectronics, Spreadtrum, MTK, Bright, Altair, Marvell and other basic only won one or two.
