A Project For CDMA450 Radio Local Call In Yingkou City

The mobile communication has been rapidly developing in the current years. It came through the analogical and digital communication modes. In the latter, the most regular technologies are Time Division Multiple Access (TDMA) and Code Division Multiple Access(CDMA). Although the launch of CDMA is late, it displays a powerful life-force.In 2000, International Telecommunication Union (ITU) declared that any nation may assign the other frequency for the Third Generation (3G) to the mobile communication. In 2001, ITU-D researched to the applied value of radio technologies, such as GSM and CDMA in the frequency of 450 MHz. By compared with these technologies, CDMA450 is one of the best project, which has the high utilization ratio of spectrum, the clear and seamless developing line and the low cost.CDMA450 adopts a kind of the core technology of CDMA2000, which modern radio communication works in 450 MHz. In the first, it is widely used in East Europe and North Europe. CDMA450 has the lower working frequency, the large coverage area, the strong penetrability, the large capability, the lower investment cost, and it supports the radio high speed package service.Departing from the basic idea of mobile communication and combining the working practice, this paper brings forward a project for CDMA450 Radio Local Call in Yingkou City, and introduces, the technology characteristic, the supporting service, the network developing of Lucent CDMA450.
