In a newly-built residential area in Shenzhen, the infrastructure and greening have been basically completed, and the owners have moved in one after another. However, the owners reported that the mobile phone signal in the underground garage was very poor, or there was basically no signal, and they could not complete the call and surf the Internet, which brought great inconvenience to the residents' lives. Therefore, the developer contacted my company for complete coverage of the cell phone signal.
The operation ship needs to be interconnected between the sea and the land, and the current maritime communication means are few and the coverage area is narrow, which can not meet the actual communication needs of customers. At present, the maritime satellite communication used by customers is expensive, and most customers cannot afford the high communication costs. They will only be used in very urgent situations.
Through advanced wireless coverage technology and powerful integrated service capabilities, we will build a high quality, efficient and cost-effective rail communication system for public network, private network, public security, government and other communication system businesses in the rail transportation industry,
Emergency satellite communication solutions Satellite emergency communication is of great significance in ensuring the safety of the country and people's lives and property, and ensuring social stability. When the disaster occurred, all the ground facilities were seriously damaged, the communication facilities were damaged, and the outside world could not be contacted in time.
With the construction and development of mobile communication networks, there are more and more types of mobile communication systems, and users need to cover the entire 2G, 3G, and 4G networks. There are many difficulties in the coverage of the whole network, such as different installation conditions and coverage area, high pressure on equipment and installation and maintenance costs, and the inability to quickly solve customer complaints, which require communication equipment suppliers to provide new products and solutions that are more targeted than traditional solutions. With the introduction of the whole Netcom system, a variety of network systems are combined together, and multiple networks can be covered at the same time in one construction, which can efficiently meet the network construction needs of operators or industries.

When the train enters the tunnel, there will be no signal, no phone calls, let alone the Internet. This seems to be common sense, and people seem to be used to it. However, in recent years, with the development of China's high-speed rail, it can be seen that on some high-speed rail lines, such as the Shanghai-Kunming high-speed rail and the Yunnan-Guangxi railway, even in the tunnel, the mobile phone signal is full. You can not only make phone calls, brush Weibo, watch Moments, but also video chat and watch live broadcasts. What the hell is going on here? How did the cell phone signal in the tunnel get full?
A few days ago, the Hong Kong-Zhuhai-Macao Bridge, a super sea-crossing project jointly built by Guangdong, Hong Kong and Macao, was opened. The opening ceremony was held in Zhuhai, Guangdong on the morning of the 23rd. It is not only the longest sea-crossing bridge in the world, but also one of the most technically complex, construction requirements and standards in the history of Chinese transportation. It is hailed as the "Seven Wonders of the New World" by the British "Guardian". But, you know what? Behind the most complex project, there is also a feat of communication engineering--
Since Chinese operators do not have any 5G trial commercial and commercial licenses, it cannot be said that China has entered the 5G era for the time being.
In the future, 5G will become an important infrastructure. If from 1G to 4G, the main solution is the communication between people, then 5G will solve the communication between people and things, things and things.
The high reliability of the repeater base station can provide a more reliable network connection. The installation of the repeater base station is simple, and the installation can generally be completed in a short time without too much installation preparation. The efficiency of the repeater base station is relatively high, and in the case of the same power, a higher coverage rate can be achieved. The cost of the repeater base station is relatively low, which can save the investment cost and allow investors to obtain a higher return on investment.
The location of the repeater base station is very important. It must not only meet the requirements of signal coverage, but also meet the specified electromagnetic compatibility requirements. When positioning the base station location, factors such as buildings, roads, terrain and soil should be considered in order to select The ideal installation location
