It is reported that the German Federal Agency for Networks will begin to compete for the 700 MHz band, which will serve high-speed mobile networks in rural areas on May 27, 2015. A total of three companies are eligible to participate in the auction: Telefnica Germany, Telekom Deutschland and Vodafone.
Germany is the first European country to use the 700 MHz band to support mobile broadband services. The 700MHz band was not occupied before, in order to use this band to achieve the transition from the DVB-T standard to the more efficient DVB-T2 standard. The DVB-T2 standard will be put into use in the spring of 2016. From April 2017, the 700 MHz band will be gradually put into use by mobile network operators. 
The domestic discussion on 700M is also continuous, some people shouted wolf, and some people said it was safe, some people feared, some people spurned, and the three major operators stalked at 700M. There are also arguments for the 700M coveted by radio and television, but domestic In the end, the 700M is in an embarrassing state. Insiders gathered the 700M past and future at the 2014 Broadcasting and Television Planning Institute Technology Exchange Conference.
1, radio and television need 700M more than telecommunications. In the 90s of the last century, China had allocated 806-958 MHz belonging to broadcasting and television to telecommunications. Today, VHF and UHF spectrum allocated to broadcasting and television are all in use, and broadcasting and TV are realistic requirements for 700MHz; allocated to telecommunications decimeter wave and millimeter wave spectrum 1/3 are not used, and mobile communication operators only need to reserve 700MHz.
2,700M is the basic condition for realizing the digitization and equalization of public services for broadcasting and television. At present, the broadcasting and television stations should make full use of the role of terrestrial TV spectrum, complete the digitalization of terrestrial television as soon as possible, and achieve the equalization of TV services in urban and rural areas in accordance with the requirements of the 18th National Congress. This is the responsibility and obligation of the broadcasting and television industry.
3, radio and television network to build the necessary resources for wireless broadband. Broadcasting and Television shall coordinate the three ground technologies of wireless, cable and satellite, improve the public service network for broadcasting and television, earnestly give play to the resource advantages of the wireless TV spectrum, and actively explore the development of wireless broadband services to meet the information services of urban and rural households (especially low-income families). Demand.
4, radio and television should speed up the application of wireless technology research. Strengthen the management and orderly use of wireless spectrum (especially UHF), learn from wireless broadband technologies such as WIFI and LTE, strengthen research on wireless technologies, and increase the efficiency of UHF rational utilization.
Summarizing the above four points, 700M is a tool for the development of new services for broadcast and television. If we want to regard cable TV network operators as one of the telecommunications operators, then the significance of 700M to cable is greater than that of the three major operators, no matter whether they are three big ones. Operators, or cable companies everywhere, the development of fixed cable broadband is ceilinged, where the coaxial cable can't be pulled in, the optical fiber can't be pulled in, and up to 250 million households with 200 million fixed wired broadband, 700M is needed. Go to cover.
In terms of achieving cultural equalization, radio and television are more operational than telecommunications. As the three major operators are listed companies in the SASAC, the KPI assessment of the provinces in the headquarters is extremely demanding. In some public services, there are no public services. The system of radio and television is even more active. Although broadcasting and television stations were separated, the radio and television companies were set up independently, foreign companies were introduced, and some were even on the market. However, the majority of the board chairman and general manager are still government-based and their pursuit of revenue and profit is not as good as Instructions to executives and supervisors are more thorough.
In the triple-play marathon race, cable TV network operators are lagging far behind the three major telecom operators. If they can get 700M, it is undoubtedly an accelerator for the rapid development of cable. Why? Is 700M not in radio and television? It is in the hands of radio and television, but not in the hands of cable operators around the country. It is in the hands of radio and television bureaus or radio and television stations throughout the country, not in the SARFT.
What about tongue twister? Dizzy? have you understood? Actually, it is very simple. China is a four-tiered radio and television company, unlike the country’s unified construction of telecommunications. Instead, the central, provincial, municipal, and county governments at all levels, in accordance with the requirements, set up their own funds and set up their own way to cover local The television stations, wireless transmission departments, and cable television network companies in the area, when the spectrum of the 700M spectrum was established at the beginning of Taiwan, it was planned to make wireless transmissions to the stations. Now that the network has been separated, the cable is coveted, but it is not enough.
Planning is a problem. Clearing is another issue. There are more than 3,000 radio and television broadcasting organizations in the country, and counties and counties have transmission tower relay stations. Due to management problems in the last century, they were broadcast, DTMB, pagers, and terrestrial digital. Radio, mobile radio, car radio, street TV, and city television have all been occupied. Just like 3,000 private plots, illegal houses have been erected. Do you want to demolition? Hey.
The problem of 700M, as well as the problem of the industry chain, is well-known that the advantage of 700M is the development of wireless broadband, the use of broadband retransmission of video or users to access the Internet, the first thing to be solved is the broadband backbone network identity of cable TV network operators, without this identity, Can not be the same as telecommunications, China Unicom does not clear each other traffic, 700M constitutes only an intranet, but also Telecom and Unicom's agents, at best, is a virtual operator.
From terrestrial wireless broadcasting to satellite TV, to cable TV, to fixed broadband, the richness and development of television transmission channels, each channel has the content, integration and support from terminal manufacturers. Today, 700M The industrial chain of wireless broadband needs to be enriched and expanded. There are television stations and program production companies, but integrators and terminal equipment vendors are still waiting to see.
In fact, this is also a headache for mobile communication operators and Ye Gonghao Long for the 700M, has deployed 2G-3G-4G-LTE, is it possible to come back to a 700M? But for the poor and poor cable network operators, it is indeed thirsty, thirsty to die. 
700M hydrolyzed the near thirst of cable operators?
