-- Realize the whole network coverage of the longest highway tunnel in Gansu

On the vast land of Gansu, a highway tunnel crosses mountains and rivers like a giant dragon, connecting hopes and dreams from afar. Recently, this longest highway tunnel in Gansu, known as the "neck-choking ring" of China's north-south artery, with the help of information technology, has achieved full network coverage of "where people are, missions must be reached, and signals are full". It marks a new step in the construction of Gansu's transportation infrastructure. This longest highway tunnel in Gansu not only shows the outstanding achievements of human engineering technology, but also realizes the seamless coverage of the entire network with the help of information technology. Behind this, it is inseparable from Guangzhou Sinan Technology Co., Ltd. The company's outstanding communication base station antenna research and development technical strength and professional services provide strong support for tunnel network coverage!

The realization of Guangzhou Sinan Technology Co., Ltd.'s full-line network coverage is inseparable from technological innovation and breakthroughs. As a leading provider of communication base station antenna solutions in the industry, with its excellent technical strength and innovation ability, it has developed and provided special road tunnel antenna products for the network construction of this road tunnel. Guangzhou Sinan Technology Co., Ltd. has deeply optimized these antenna products for the special environment of the tunnel, which not only greatly reduces the workload and risk factor in the construction process, but also effectively provides antenna performance and ensures the stability and quality of the network signal inside the tunnel. This tunnel distribution system adopts the latest tunnel-specific wall-to-wall antenna of Guangzhou Sinan Technology Co., Ltd., which is reduced from 32 points of the traditional scheme to 128 pairs of logarithmic periodic antennas to only 8 points and 32 pairs of road wall-to-wall antennas. It not only greatly reduces the workload and risk factor, effectively improves the antenna performance, but also guarantees the high-quality network signal. The latest tunnel-specific wall-to-wall antenna of Guangzhou Sinan Technology Co., Ltd. is a centralized antenna with good directivity and high gain. It does not need to be installed with a pole, thus improving the coverage effect and reducing the construction difficulty and safety risks.

Its working frequency band is 698~960MHz/1710~2170MHz/2300~2700MHz. The antenna can cover the UHF band and the low frequency band to achieve a wider frequency range. Through the use of advanced antenna design technology, it can maintain a stable gain and low beam width in a wide frequency range, so as to achieve stable long-distance communication on the road. The antenna adopts wall-to-wall design, compact shape, can be easily installed on the road, reduce the interference to road traffic. It occupies a small space and can adapt to various environments and installation needs. Easy-to-use maintenance interface for easier maintenance and upgrades. At the same time, the antenna has good compatibility, can be seamlessly connected with other devices and systems, to achieve cross-platform, cross-system communication and data transmission. Compared with other antenna technologies, the antenna has lower cost and higher performance, helps to reduce construction costs and operating costs, and meets the needs of road communication. The overall construction cost is 80% lower than the leakage cable scheme, and more than 30% lower than the log-cycle antenna scheme, saving investment is obvious.

These two technologies and equipment are used for the first time in Gansu Province, which provides a strong guarantee for the stable transmission of signals in the tunnel. In the process of tunnel network construction, Guangzhou Sinan Technology Co., Ltd. gave full play to its communication base station antenna research and development technical expertise, and worked closely with the construction company to overcome many technical problems. Through careful design and construction, the tunnel has achieved all-round, no dead angle network coverage, whether it is traffic monitoring, emergency communication or passenger mobile Internet needs, have been fully met. The achievement of this remarkable achievement is inseparable from the full support and outstanding contribution of Guangzhou Sinan Technology Co., Ltd. In this regard, the Communications Development Department of China Tower Dingxi Branch expressed sincere and high praise to Guangzhou Sinan Technology Co., Ltd.

The "choking ring" of China's north-south artery-how can the longest highway tunnel in Gansu Province achieve full network coverage? this achievement has not only improved the information level of highway tunnels in Gansu, but also set a new benchmark for the construction of intelligent transportation. With the continuous development and popularization of network technology, the future traffic will be more convenient, intelligent and safe. Guangzhou Sinan Technology Co., Ltd. will continue to uphold the spirit of innovation and contribute more to the development of the transportation sector. Looking forward to the future, the coverage of Gansu highway tunnel network will continue to improve, and the construction of intelligent transportation will achieve more brilliant achievements. Guangzhou Sinan Technology Co., Ltd. will also work with all parties to jointly promote the prosperity and development of the transportation industry and contribute to the construction of a better travel environment.
