The mainstream application technologies of wireless monitoring systems, such as 3G, WIFI, WIMAX, etc., are affected by factors such as the frequency band and transmission power of microwave signals. The performance of each of the technical parameters such as network transmission rate and coverage is very different. WiMAX and 3G are used for high-speed image transmission, and 4G is not widely used because of the limitation of universal coverage... This article refers to the address: http:// Surveillance technology has entered the realm of multiple wireless monitoring applications. Various security monitoring devices can carry a variety of wireless transmission interfaces and media types, from GPRS, Z-wave, Zigbee and WSN, which transmit data signals to broadband wifi. WiMAX and ultra-wideband 3GTD, and then 4GTD-LTE, are basically the transmission technologies that wireless security monitoring systems can use. The only difference is that the benefits of wireless image monitoring applications are different. The mainstream application technologies of wireless monitoring systems, such as 3G, WIFI, WIMAX, etc., are affected by factors such as the frequency band and transmission power of microwave signals. The performance of each of the technical parameters such as network transmission rate and coverage is very different. WiMAX and 3G are used for high-speed image transmission, and 4G is not widely used because of the limited coverage. The following application claims for wireless monitoring transmission are feasible on wireless security monitoring, and there are specific application scenarios: Personnel and vehicle satellite positioning tracking anti-theft monitoring; Remote automatic monitoring system for digital simulation data; Remote automatic monitoring system for power parameters such as power distribution; Real-time and non-real-time remote image monitoring systems; Public remote monitoring system for public infrastructure construction; Elevator fault remote automatic monitoring system; Remote fault monitoring system for lighting faults; Building automation data remote wireless capture system; Remote automatic monitoring system for environmental control parameters; Building access control and disaster prevention remote wireless monitoring system. In addition, a brief description of these types of broadband wireless technology in the wireless monitoring market, mainly for WiFi (WirelessFidelity) 802.11b standard and WiMAX (Worldwide Interoperability for MicrowaveAccess), namely the global microwave interconnection access, mainly used in urban wireless monitoring. WiFi image monitoring has the following advantages: The signal transmission radius can reach about 100 meters, which can be applied in the office or even the whole building; The transmission speed is very fast, it can reach 11-54Mbps, which meets the needs of personal and regionalized image and information transmission; The threshold for manufacturers to enter this engineering field is relatively low. As long as the AP "hotspot" is set in the monitoring scope project and the Internet is connected to the above-mentioned places through high-speed lines, the monitoring will only need to support the wireless LAN laptops, workstations, and even When the mobile phone or PDA is in the area, the image transmission wireless network can be accessed at high speed. WiFi is widely used and is the most widely used wireless technology in wireless surveillance. And after years of development of WiFi in short-distance transmission, WiFi has already had a good application basis, mainly used in wireless network cameras, and many domestic WiFi wireless network cameras also have good performance. WiMAX, as an international 3G standard, has not been widely used in China. The main reason is that WiMAX has not obtained a license to land in China at this stage, and it is impossible to build a network base on a large scale. The advantages are summarized as follows: WiMAX has a longer transmission distance and can realize wireless signal transmission of 50 kilometers. The network coverage area is 10 times that of 3G (TD-SCDMA) tower. As long as a small number of base stations can achieve citywide coverage; Provides higher speed broadband access (up to 70M), 30 times that of 3G; As a wireless metropolitan area network technology, it can connect WiFi hotspots to the Internet, or as a wireless extension of wired access methods such as xDSL, to achieve broadband access in the last mile, and to provide multimedia communication services. With the above advantages, although WiMAX has not been widely used in China, WiMAX is an ideal transmission method for wireless monitoring, and has received the attention of domestic users. Currently, high-end residential applications use WiMAX to structure image monitoring. system. In addition to the above two transmission technologies, the global mobile communication industry is more concerned about the future development of 4GLTE (LongTermEvolution). LTE is developed by the 3GPP organization and can be said to be the ultimate version of 3G. It can download 100Mbps and upload 50Mbps at 20MHz bandwidth, and the bandwidth and speed are improved. Therefore, it is considered to be more suitable for transmitting large image data such as files. Among them, the application of image monitoring system is the most popular application method of ultra-high bandwidth wireless monitoring system in China.
