The future two kinds of standard hybrid network has become a big trend

Tencent Technology reported on May 15

Although the Ministry of Industry and Information Technology issued the TD-LTE 4G license to the three domestic telecom operators at the end of last year, they are more eager for China Unicom and China Telecom to make FDD-LTE licenses matching their 3G development.

Compared with China's independent standard TDD, FDD has become the mainstream 4G standard in the world. Meanwhile, the downward development of FDD in China Unicom and China Telecom's 3G standard is more in line with the evolution of technology. However, as the mainstream telecom equipment manufacturers are well supported by TDD and FDD two 4G standards, the future two standard hybrid networking has become a trend.

There are recent signs that FDD-LTE licenses are about to be released soon, even starting trial network licenses are enough to cheer China Unicom as they can fight China Mobile with enough power to develop their own tastes. After all, China Mobile is the dominant force in TDD technology. In the case of only TDD licenses, it is very difficult for China Unicom to compete with mobile.

Although there is no accurate FDD license date, but Unicom and Telecom denied follow-up competitive strategy, according to Tencent Technology, once issued FDD license, China Unicom and China Telecom's 4G network planning, a wide range of wide The coverage of the 4G network using FDD standard, and urban areas densely populated areas will use TDD standard to absorb excess traffic.

FDD license is approaching

All along, the FDD-LTE 4G license has never been released when the message from the day of the release of the TD-LTE 4G license, a wide variety of claims will emerge in an endless stream, some of the recent industry news this time locked in the industry-specific " 5.17 Telecom Day "on.

When the license is issued by the Ministry of Industry, Tencent Technology confirmed to the relevant person in charge has not been confirmed, the three operators also Tencent said they did not receive the relevant documents, but no wind without waves, there are multiple media Announced that FDD will be officially released on "5.17 Telecom Day."

It is learned that the theme of this year's "5.17 Telecommunication Day" is "Broadband Promotes Sustainable Development", stressing that today, with networking, broadband has become a transformational tool that can accelerate sustainable development. If you issue FDD-LTE 4G license at this time, it seems that the theme does not take. However, the development of wireless networks to 4G, and even future NG, are inseparable from the support of fixed-line broadband, from this point of view is not impossible to release.

Tencent Technology learned from other sources, the telecommunications day will not be issued FDD-LTE 4G commercial license, but does not rule out the FDD-LTE 4G trial network license will be issued, because the FDD-LTE network deployment has not really begun, the issuance of commercial licenses It is not very meaningful, but no licensee can not openly invite public bidding for scale deployment. Therefore, the trial network license is reasonable and initially targeted at only some cities. This is similar to the initial trial conducted by China Mobile on the TD-LTE trial network in multi-cities.

Xiong Yu, general manager of China Unicom's marketing department recently told Tencent Technologies that after the FDD license, China Unicom will further increase the speed of 4G network construction and is expected to achieve 4G network coverage in 300 domestic cities by the end of this year. Among them, 42M 3G networks, 100M TDD 4G networks and 150M FDD 4G networks are deployed in hotspot cities.

Due to the embarrassing situation of China Telecom CDMA in 4G evolution, its position is more neutral. "The issuance of FDD licenses has a positive effect on TDD because there is a total of 90% technological overlap between TDD and FDD in the world. The issuance of FDD licenses is conducive to the participation of Chinese enterprises in international competition as well as the international roaming of consumers because 95% The network format used by 4G users is FDD or TDD mixed with FDD. "A Chinese telecom operator said to Tencent Technologies.

It is understood that once the FDD license is issued, in the 4G network planning of China Unicom and China Telecom, the large-scale and widely-covered 4G network uses the FDD standard, while the urban area populated areas will use the TDD standard to absorb excess traffic.

4G contest has just begun

2014 was considered the first year of 4G in China. As one of the important forces driving the consumption of information, the development of China 4G in this year deserves our attention. Especially after the issuance of the FDD license, the real contest between the three major carriers began.

In the past half a year, China Mobile fully promoted the rapid development of autonomous 4G standard TD-LTE. Network coverage, terminals and tariffs can be described as going hand in hand. In particular, network coverage, from the first few cities, the signal instability now covered 100 downtown area, outdoor signal fluency.

Although China Unicom and China Telecom also own TDD-LTE licenses, they are more willing to invest fully in the latter's FDD-LTE licenses, which are more suitable for themselves. Tencent technology from the point of view of view, so far in the deployment of two TDD base on the number of very few, the country together but not more than 10000, and China Mobile has completed 250,000 4G base station construction.

As for the first quarter of this year, the net reduction of the number of China Mobile's mobile subscribers was 2.38 million. China Telecom said the drop in mobile subscribers was mainly due to the launch of LTE services by its competitors and the enhancement of marketing and sales promotion as market competition intensified. Analysts believe that although China Telecom won the TDD LTE 4G license in December last year, it has been actively applying for the FDD license because of terminal constraints and the inability to develop large-scale users. The FDD license, if scheduled, will effectively address the mobile advertising and marketing offensive to curb the momentum of declining business.

In addition, the industry said that China Unicom TDD LTE license obtained last year is nothing more than tasteless, if long-term can not get the FDD license, its 3G era accumulated network advantages and user reputation will also be depleted. Therefore, the sooner FDD is released, the more favorable the development of China Unicom will be.

Due to the issuance of TD-LTE license, the current three major carriers of the 4G war is not building network level, but tariff war precedent. If the first half of China Mobile 4G "a dominance" situation, then once the FDD license issued, the three operators 4G contest really started.
