Detailed description of CDMA wireless router application cases

With the rapid development of China's routing technology, the CDMA wireless router technology is also constantly upgrading. So I have studied the actual application cases of CDMA wireless routers and will share them with you here. The ATM system network of a bank needs to be transformed and connected to the center wirelessly without changing the system structure of the original network, including the networking mode and software.

The ATM machines form a LAN, and the IP address is assigned to the center. The center is the same as the LAN structure. The whole system requires that the LAN of multiple ATM machines be connected to the central LAN, this completes the center's monitoring of ATM machines. The transformation scheme mainly includes technical complexity, feasibility, cost, implementation cycle, operation cost, transmission data security, and maintenance cost.

Analysis and Solution

Factors to be considered in the scheme design include: the WAN for communications, the communication terminal equipment, and the architecture of the data center. These three factors are linked in the entire solution. Within the financial system, backbone networks of financial communication private networks at the provincial, municipal, and county levels have been basically built. Access Networks for various businesses in cities and counties are also under construction. The access network requires many network elements, multiple straight lines, wide distribution, and low investment. The financial and communication industry has chosen a variety of wireless communication methods, but they have not been used and promoted for a long time due to factors such as network construction costs, frequency point management, transmission quality, bandwidth restrictions, and maintenance capabilities. Traditional methods have the following shortcomings:

1. Traditional ATM networks are usually deployed with optical fiber cables. The investment is too large and the maintenance cost is high. In addition, the leased line rental fee must be paid to the Telecommunications Department on a monthly basis.
2. the wireless data transmission station has a geographical obstacle, high interference, high cost investment, high lightning protection requirements, and inflexible.

Solution

China Unicom's CDMA wireless router can make up for the shortcomings of wireless communication in the financial communication private network. The CDMA Wireless Router network can cover most regions, and the coverage rate is constantly increasing. The upstream and downstream bandwidth can reach about 60 Kbps, and the standard IP protocol is supported. Currently, CDMA wireless routers are charged by traffic and are billed by monthly subscription. In this solution, select the CDMA Wireless Router Network. The scheme requires that communication devices have the routing function to connect the ATM and central control networks and access each other.

The CDMA wireless router launched by Beijing yinghantong Corporation provides a good communication platform for the ATM system networking. This product uses Unicom's CDMA wireless router 1X as the bearer network and has the routing and VPN functions, it can connect the ATM network to the central network and directly access the IP address of the ATM. The networking mode is the same as that of the original banking system. The entire solution does not need to change the banking center system and procedures.

Advantages

1. Meeting the bank's transformation requirements, without changing the structure of the original bank network and the central system program .,
2. The network is simple and successfully connected to the ATM and bank center networks distributed across different regions.
3. China Unicom's CDMA wireless router 1X network provides stable and reliable data bearer networks for commercial users without maintenance.
4. The implementation cycle is short, saving the heavy workload of traditional wired network deployment.
5. This product has the VPN function. In the networking mode, the remote LAN and local LAN are in a virtual private network to ensure the security and reliability of data transmission.
6. The communication fee is much lower than the traditional leased line communication fee.
