New Use of Wireless Access Network Technology

The wireless access network technology is widely used in many fields. Here we will mainly introduce key wireless monitoring technologies, including the establishment of wireless links. Traditional video surveillance systems use analog video transmission and storage technologies to achieve satisfactory image quality at a relatively low cost. With the development of digital video coding technology and Internet technology, a digital video surveillance system based on Ethernet as the transmission medium has emerged and is transmitted over a computer network. The emergence of Wireless Access Network Technology Ethernet brings a new way of application to the monitoring system. The Digital Monitoring System of wireless access network technology, based on the original Ethernet Monitoring System, discards Network cables and transmits data using wireless access network technology microwave, reducing the cost of network wiring, it enhances the flexibility and scalability of the monitoring system.

Wireless Digital monitoring is one of the most widely used wireless access network technologies. In general, the monitored sites and central control centers are far away from each other and their locations are scattered. The traditional network cabling method is not only costly, but also when encountering obstacles such as rivers and mountains, wired networks are helpless. In this case, the unparalleled advantages of wireless networks are shown. Using the wireless bridge technology, multiple monitoring sites can be connected to the central control center and established quickly, you can quickly establish a wireless network link in the shortest time. If conditions permit, a wireless bridge can support bridging up to 50 kilometers. AboveCable IEEE802.11b/g/a Wireless Access Network Technology Network products support 11, 22/54 Mbps and higher network bandwidth, digital video streams in H.263/MPEG-1/2/4 format can be reliably transmitted to achieve wireless video surveillance.

Key wireless monitoring technologies

In the Monitoring System, the wireless network is mainly used to connect the monitored point and the data transmission link of the monitoring center. The wireless network can connect multiple remote monitoring site devices for video transmission. At the same time, the monitoring system has high requirements on video quality, how to transmit stable and high-quality video information in wireless networks is also one of the key technologies to be addressed in wireless digital monitoring systems. In addition, from the perspective of engineering implementation, bridging devices are often installed outdoors, how to provide long-distance power supply and equipment management for these devices is also worth noting.

Establish a wireless link

The video monitoring system mainly implements how to transmit video files collected by monitoring sites in real time to the monitoring center in a timely manner. Usually, the monitored points and monitoring centers are separated from each other, and the distribution of monitored points is relatively scattered. The traditional wired connection method is not only costly, difficult to build, but also long construction period, in addition, it has poor scalability and flexibility. to increase or reduce the number of monitoring sites, a new construction cycle will be introduced. The wireless access network technology uses a wireless bridge to connect two isolated networks and transmit data through the wireless bridge. The wireless link provided by AboveCable Wireless Access Network Technology can achieve high bandwidth of 11 Mbps/54 Mbps, ensuring stable and continuous transmission of video streams. If you use a Wireless Bridge, no cabling troubles, no damage to the original environmental facilities, short construction period, high cost performance, and strong scalability, you only need to increase or decrease the wireless access network technical Bridge of the monitored point, you can increase or decrease the number of monitored points.
