The banking and securities networks are currently mainly built on the basis of traditional telecommunications digital networks, implemented through DDN, FR, remote dial-up, etc. Their main drawback is the network structure Fixed, difficult to change, and costly. The data transmission system built on a wireless network platform can enable the bank's headquarters, branches, and settlement centers to continue using the previous system A high bandwidth dedicated network, while for dispersed business outlets, bank POS machines, and ATM machines, they can transition from remote dial-up networks to wireless networks Up, the wireless network ensures that all wireless terminals of an enterprise are connected to the same closed VPN private network through security measures. Once they enter the VPN private network, they will be terminated,The end also needs to pass the bank's AAA certification to enter the settlement database. A series of security measures can fully ensure the security of the transaction network. 

industry characteristics:
1. High security requirements. When encountering disasters such as wind, rainstorm and breach, data information cannot be transmitted in time once the line is disconnected,Therefore, wired transmission has poor disaster resistance and is difficult to meet high reliability requirements. In addition, the terrain of the watershed is complex and remote, and the cost of laying optical fibers is also relatively high. By contrast,Wireless communication wiring is simple, convenient, has good disaster resistance, and has relatively low costs, which can save a lot of investment.
2. There are many savings offices and branch offices in various regions, which are widely distributed geographically and located in remote areas. Therefore, wireless bridges are required to have a longer transmission distance. 
3. Considering the real-time and accuracy of bank data transmission, the stability and security requirements for wireless links are extremely high. 
4. Generally, the data required for various savings needs to be summarized in the branch offices first, and then transmitted back to the central business department by each branch office. Under normal circumstances,Each branch business hall and the central business department have been wired connected. 
5. Strong data security and confidentiality. 
6. Wireless links can be used as backups. 
7. The device provides an Ethernet interface, which is plug and play, easy to install, and convenient to debug. 
8. When working 24/7, an outdoor wireless bridge should be selected.
