The next generation of wireless technology is undoubtedly the protagonist of 5G, it is not only the direction of smartphone communication development, but also the future wireless highway. 5G technology is at least 100 times faster than 4G, can broadcast video almost zero lag time, and download a complete movie in a few seconds, and with the various high-resolution trends of visual effects, we will not have to be speed And worried. 5G technology is actually a big leap and will bring a new revolution to all industries.
China's three major operators are expected to invest nearly 200 billion US dollars for the construction of 5G infrastructure. China Mobile has announced that it will set up a 5G experimental network in major cities this year. The Tianjin network that has been built has already achieved 100 times faster than 4G. speed. China Telecom has launched 5G pilots in cities such as Xiong'an, Shenzhen, Shanghai and Suzhou. It is expected that China will realize 5G commercialization by 2020 at the latest.
Ultra-dense networking in the 5G era spawns small base station requirements
The number of base stations in the 5G period will be greatly increased, which will increase the cost of network construction for operators. The small base stations have the advantages of flexible deployment and small co-channel interference (the deployment between 10 and 20 meters can be achieved, and the deployment distance of the macro base stations can be compared. Generally need to reach more than 500 meters), very suitable for hot area coverage, or will become the main way to increase the site of the 5G era base station.
Installing a small base station on a smart street light will be one of the most feasible ways
At present, the deployment mode of small base stations is mainly divided into indoor coverage and outdoor coverage. The specific deployment methods for outdoor coverage are as follows:
(1) Installation of poles: Installation by roadside cement poles, meter boxes, etc.
(2) Floor installation: deploying an integrated micro-station, using the D-band with the large-frequency inter-frequency, suitable for high-rise construction with signal shielding.
(3) Ground installation: The vertical small base station is directly deployed on the ground.
The installation method based on smart street lamps is a typical way of pole installation, with the following advantages:
(1) Power supply advantage: The combination of small base station and street light can share the charging device, save energy, and solve the power supply problem of small base station deployment alone.
(2) Management intelligence: Through the sensing device on the smart street lamp, it is convenient to monitor the running status and temperature of the small base station, and find that the abnormality can be timely warning, and also can transmit various types of monitoring data to the cloud, which is convenient. Analysis and utilization.
(3) Intensive coverage: Since the coverage of a single small base station is less than 200 meters, it is necessary to carry out intensive deployment to fully cover the blind spot, and the street lamps are evenly distributed with a spacing of less than 100 meters, which can help the small base stations to form dense coverage.
(4) Space saving: The combination of small base station and street light saves the space required for separate deployment, which can greatly reduce the difficulty of property coordination for base station deployment.
(5) Blind spot coverage: Highways and railways are often places where signal coverage is not good. The installation of smart street lights is conducive to blind spot coverage.
Currently, this model has been promoted overseas. The Canadian operator TELUS and the power company replaced the shares, and installed the small base stations in batches on the infrastructure such as the telephone poles owned by the latter; Vodafone cooperated with a Dutch company with the right to distribute the advertisements of the bus stations, using the space installation of the bus station. Small Cell, an advertising company not only gets rentals, but also uses the big data capabilities of operators to deliver dynamic, targeted ads.
Installation of 5G base station will drive 117.6 billion smart street lamp market
By the end of 2017, the three major operators had built a total of 4.89 million 4G macro base stations (including China Mobile 1.87 million, China Unicom 850,000, China Telecom 1.17 million).
The number of base stations corresponding to the coverage radius of the reference spectrum, we predict that the 5G macro base station is about twice the 4G, and the number of small base stations in the 3G era with reference to foreign operators reaches 1.5-2 times the number of macro stations. In summary, we predict that in China. In the first four years of 5G network construction, the number of small base stations will reach 11.67 million (389*2*1.5=1167) sets, with an average annual average of 2.92 million sets. At present, the average price of 4G small base stations is around 2,500 yuan. The estimated annual market space is 292*0.25 million/set = 7.3 billion yuan.
According to the outdoor indoor deployment ratio of the small base station is 8:2, the annual average market size of the outdoor small base station can reach 5.84 billion yuan (73*80%=58.4). Due to the perfect integration of small base stations and smart street lamps, small base station deployment based on smart street lamps is the main form of outdoor deployment. According to 90% calculation, the average annual market size of small base stations based on smart street lamps can reach 5.3 billion yuan (58.4*90%= 52.56).
The small base station itself is not expensive, but the installation cost is high. At present, residential building floor installations need to pay a site lease contract of more than 10,000 yuan per year, and the cost of installing base stations on smart street lamps will be greatly reduced. Assuming the initial installation fee is 14,000 yuan, the installation of 5G base stations will drive 117.6 billion. Smart street light market (1167*0.8*0.9*1.4), with an annual average of 29.4 billion.
Therefore, the smart street lamp will be the first site for intelligent urban transformation, and it is the main threshold for the city to move toward the process of intelligence. In the future, smart city construction and smart street lights will take off together with cloud construction, communication infrastructure construction, and base station construction.
