From the perspective of spectrum, the higher the frequency band, the more it will increase the cost of network coverage, and the technical requirements for system equipment and terminals are also higher. At present, the country has allocated 190MHz frequency resources in the 2.6GHz frequency band to TDD, and the two unallocated 60MHz in the 1800MHz and 2100MHz frequency bands are used for FDD. The 2.6GHz frequency band belongs to the microwave frequency band. Due to the high frequency and short wavelength, the straight line will be reflected or blocked when it encounters obstacles, which will increase the cost of future network coverage for operators and the technical requirements for equipment manufacturers and mobile phone terminal manufacturers. improve.
From the perspective of radio and television, the three-network integration two-way business access mechanism has opened the door to the basic telecommunications industry, and the 700MHz 4G golden frequency band is undoubtedly a weapon for the telecommunications market. The 700M frequency band has low frequency, high penetration, large coverage and other excellent characteristics, which can reduce the cost of network construction. In addition, because it is close to the mainstream mobile communication frequency band, a large number of existing network resources can be reused, so the 700M frequency band resources Has a high commercial value.
At present, due to the interests of all parties involved in the integration of the three networks, people in the radio and television industry even pointed out that the broadcast of the 700M frequency band is just like the United States assigning "Pearl Harbor" to China. Du Baichuan, deputy director of the Radio and Television Science and Technology Commission, also said that radio and television must be involved in 4G services, and the 700M frequency band is unique! Earlier, there were rumors that the domestic 4G will be licensed at the end of 2013. In addition to the three major operators, one will be reserved for the Chinese radio and television network company under construction under the radio and television. In addition to the advantages gradually revealed in 4G, the broadband network has developed rapidly in terms of fixed-line broadband. With the help of its local cable network companies, the number of cities covered has surpassed the Great Wall Broadband and has become the "old five" after the traditional top four. Coupled with the advantages of the fixed network, the 700MHz frequency band has added many variables to the development of the triple play market, and the radio and television will undoubtedly become more powerful.
In the process of transition to 4G, China has basically been on the same starting line with developed countries in Europe and America. 4G's requirements for spectrum resources are becoming higher and higher, and the mobile Internet enabled by 3G has brought a full range of impacts from technology, business to business models to the telecommunications industry. Under this background, developed countries such as Europe and the United States have begun to actively explore and It has formed a globally important new spectrum strategy, fully explored the maximum value of spectrum resources, and strived to protect it from the reform of the management mechanism. It is reported that the frequency band (700MHz band) for terrestrial analog TV signals has been widely released internationally for 4G. Not only terrestrial analog TV signal bands, telecom operators in the United States, Finland, Japan, New Zealand, South Korea and other countries have set a schedule to shut down 2G networks, hoping to release more spectrum resources for next-generation networks.
Looking back at China, judging from the disputes between broadcasters and operators in the 700MHz band, China ’s spectrum allocation has long adhered to traditions, making the conflict between spectrum resources and new technologies and new services. The huge demand for spectrum in 4G has made China ’s huge demand for spectrum The shortage of spectrum resources is compounded by the shortage of snow.
In the context of the rise of mobile Internet OTT applications, the telecommunications industry ecology has undergone tremendous changes. Radio and television and telecommunications have long been difficult to be alone, but they are also heavily barrierd. The original vision of the three-network integration was two-way entry for telecommunications and broadcasting. However, when the radio and television parties enter into broadband and other telecommunications services, telecom operators are facing a crisis of pipeline, OTT applications shine on the stage set by telecom operators. Therefore, no matter whether it is the integration of three networks or the development of 4G, the advancement will inevitably be at the expense of the cost. We should look at it a little longer and do n’t lose money.
PufangTech has designed and produced a number of data radio modems that enable data terminal devices to exchange data from miles away. PufangTech`s radio modems can do the job faster, easier, and less expensively than stringing cable. Easy plug-and-play set-up saves installation and maintenance time.
These compact and rugged units are compatible with Modbus and Profibus so no additional converters are required. They provide a compact and flexible solution for many different long-range applications.
PufangTech`s data radio modems are particularly well suited for outdoor use under varying weather conditions. By using these data radio modems, networks become flexible, easy to expand and can cover a wide variety of solutions from simple point-to-point connections to large networks consisting of hundreds of modems.
