ATM Technology Based On WCDMA

With the rapid development of technology, the wireless digital technology in the financial and other industries has been widely used, its from the original only to provide services for the user terminals can be developed to provide nterprises with secure and stable digital switching platform. Companies can achieve on this platform not only traditional telecommunications line previously used on all applications, but also broke through the line in the region point to point on the limit, so that their applications do have a cell phone signal coverage areas will be able to access the digital network.3G networks based on ATM machines from a line business is one of the more successful practical cases.With the rapid economic development and market competition intensified, the major commercial banks in the ATM machine into a fast-growth phase, running is gaining momentum. According to forecasts China Union Pay, ATM machines in 2010 ownership of more than 20 million units, around 2014, China's ATM market in urban areas around 41 million units, with an average annual growth rate remained at around 20%.Traditional off-line ATM machine or branch-type, self-help terminals main networking using wired network, but the building has been built in the city or in construction projects in remote areas, some places do not have the construction conditions, or construction costs are high, slow-building and post-network lines such as the maintenance is extremely difficult, bound from a line of financial sector to promote the pace of large-scale ATM machines.The growing maturity of the 3G WCDMA network technology, ATM machines from the development of a line provides a platform. Because of its wide bandwidth WCDMA, anti-fading performance, uplink and downlink to achieve coherent demodulation, a substantial increase link capacity. WCDMA system uses fast power technology, the transmitter is always at a minimum transmit power level, thereby reducing the multiple access interference. These techniques improve the system capacity, so that more abundant types of business conducted, the data rate further. Better multipath reception processing capabilities to enable wireless transmission of 3G WCDMA network is more perfect.Constantly improve the VPN technology for wireless ATM machine from the realization of a line provides security guarantees. Virtual Private Network (VPN) is defined as through a public network (usually the Internet) to establish a temporary, secure connection, is a public network through the chaos of the security, stability of the tunnel. Virtual Private Network can help remote users, branch companies, business partners and suppliers with the company's internal network connection to establish credible security and ensure the security of data transmission. VPN security guarantees mainly four techniques:tunneling, encryption technology, key management and user authentication techniques and equipment.In this paper, combined WCDMA network technology, VPN technology,3G wireless router features, respectively, from program design, technical support, security policy and the specific case, and several other aspects of wireless networks based on WCDMA from a line ATM technology, ATM will machine by leaps and bounds to provide strong protection.
