Foreign 700MHz fast layout or auction or planning
A global mobile communications association's research report for the Asia-Pacific region shows that if the Asia-Pacific region uses the 700MHz band for mobile communications in 2015, the Asia-Pacific region's GDP will increase by nearly $730 billion by 2020, while the deployment of broadcasting services is only 730. Billions of dollars; taxes will increase by more than 130 billion US dollars, if the application of broadcasting business can only increase by 28 billion US dollars, it can be seen that the economic value of this band is huge.
At the 2012 World Radio Conference (WRC-12), the 700 MHz band was defined as “the primary frequency resource common to broadcast network operators and cellular broadband network operatorsâ€.
At the 2015 World Radiocommunication Conference (WRC-15), the International Telecommunication Union (ITU) stated that the use of the 694MHz-790MHz band for mobile broadband would be of great help in bridging the digital divide worldwide.
Foreign governments and operators have gradually taken action and the digital dividend of 700 MHz has begun to be gradually utilized.
In Germany, the auction was first launched in May 2015 and ended in mid-June. From the auction situation, 700MHz is the most popular frequency band. Deutsche Telekom's 700MHz will be used for rural area network coverage, and it is indicated from 2019. The band will be fully utilized from the beginning of the year.
At the end of 2015, France auctioned the spectrum for 700MHz, and the first day of auction auction exceeded 2.7 billion euros. The operator's pursuit of 700MHz is evident.
The British government also recently stated that it will invest 550 million pounds in the next five years to clean up the 700MHz band and use this spectrum for mobile broadband.
In South Korea, due to the growing tension between mobile operators and broadcasters, the Korean communications regulator KCC also hopes to have a retire strategy for the release of 700MHz.
Singapore is also considering releasing the 700MHz spectrum, and IDA, the country's information and communication control agency, plans to allocate a total of 225MHz of spectrum resources in early 2016, including the 700MHz band.
Domestic 700MHz dragging the pace is too slow
Compared with the rapid layout of the global 700MHz band, even in March 2015, Taiwan’s big brother officially obtained the additional 5MHz 700MHz 4G band approved by the NCC, and the mainland is slightly behind.
From the existing broadcast TV station database information, monitoring results and the coverage of analog TV broadcasts announced by broadcasting and television: In the 700MHz spectrum of major large and medium cities, the 700MHz frequency band is used very rarely, and the high power transmitting station is less. The frequency sweep results of operators in multiple cities also indicate that the overall utilization of the 700 MHz band is low or even low.
Wei Leping, director of the China Telecom Science and Technology Commission, also said in public that the 700M premium frequency is not fully utilized, which allows operators to build networks in the 1.8G and 2.1G bands, which will bring huge financial pressure to operators. . The lack of supervision and the inability to rely on, the operators are at a disadvantage in many disputes.
The national terrestrial digital TV broadcasting coverage network is basically completed. It is expected that by 2020, the terrestrial analog TV signal will stop broadcasting, and the 700MHz frequency band will eventually be vacated.
Radio and television operators conduct public bidding in Guangdong, Chongqing, Guizhou and Gansu provinces. The bidding documents clearly require that the manufacturers of bidding equipment must have the ability to participate in the supply of telecom operators 4G (TD-LTE/FDD-LTE) in China. A supply contract for similar bidding products to domestic telecom operators within the past three years shall be provided.
However, this open tender seems to lengthen the timeline between the broadcasting and television operators and the 700MHz game.
In this regard, some insiders said: Since broadband China, information consumption, universal service, and Internet+ are national strategies, why is the 700MHz gold band, which is vital to mobile communications, not handed over to the communications operators from the broadcasting and television system? This time, the date of return was dragged from the original 2015 to 2020. "While the four provinces, radio and television start LTE equipment bidding can be described as 'attacking to defend', not only from the telecom operators to split the cup, but also to keep the 700MHz band in hand, the implementation is still ostrich tactics."
Fu Liang, an independent IT and telecom analyst, believes that it is no longer necessary to invest heavily in building such an independent power grid in the country's active promotion of triple play and Internet+. "In particular, 4G has entered the middle and late stages of construction. Equipment manufacturers and operators are already in the 4G+ and 4.5G layouts. The Ministry of Industry and Information Technology has made it clear that in 2016, it will actively carry out 5G research. It also takes the scarce 700M frequency band to build a huge investment but only for broadcasting and television signal transmission and two-way interaction. A network that is subject to many restrictions will bring huge waste of social resources."
Therefore, Fu Liang suggested that the state suspend the construction of radio and television cable and wireless satellite convergence network, set up a special national three-network integration promotion leadership and national informationization think tanks, break the boundaries of departmental interests, and promote the integration of the grid, telecommunications network and Internet from a higher level. development of. “It is recommended to co-ordinate the allocation of very scarce spectrum, break the separation of the blocks, and maximize the efficiency of the utilization of spectrum resources.â€
Perhaps this issue will be resolved. Recently, the Ministry of Industry and Information Technology issued a summary of the reply of the 2340th proposal of the 12th National Committee of the CPPCC National Committee. It means that it is necessary to strengthen the centralized management of frequency resources, and also explain the marketization reform of starting frequency resources, and proposes to build a sound radio management rule of law system.
It is understood that in the next step, the Ministry of Industry and Information Technology will continue to promote this work. First, further strengthen research on the classification of spectrum resources, charging system, and supporting regulatory mechanisms; second, continuously improve relevant policies and regulations, and steadily advance relevant pilot work; The third is to use the administrative examination and approval and market-oriented allocation methods to gradually cultivate a market-based allocation system for spectrum resources with Chinese characteristics.
In fact, in August 2015, the Qinghai Radio Management Office stated that the radio spectrum is a scarce resource in the country. In the construction of public communication networks using the 700MHz frequency band, it is necessary to strengthen the 700MHz frequency band research, actively promote commercial use, and create new economic value for the society.
As early as 2014, Fengqiao Town, Shaoxing City, Zhejiang Province, opened the first domestic 4MHz TD-LTE base station in the 700MHz frequency band, and completed the single station coverage comparison test with the TD-LTE system in the same site 2.6GHz frequency band.
It is understood that the test results are: in the rural environment, the 700MHz TD-LTE coverage radius in the low frequency band is about 3-4 times of 2.6GHz, and the coverage area is about 10 times of 2.6GHz. In the outdoor environment, the average signal strength of 700MHz is 20dB stronger than 2.6GHz, and the indoor environment is 20-30dB stronger than 2.6GHz. According to the communication principle, 700MHz good propagation characteristics and coverage capabilities will greatly reduce the cost of TD-LTE network construction.
