How is bandwidth increased in cdma2000
WebCDMA2000 are also finding acceptance in the commercial arena. IMS/Convergence is increasingly popular all over the world; ... In order to adapt to new services, increasing demand for user bandwidth, quality of service and requirements for network convergence, major evolutions are introduced in 3G network Weblines [1]. One of the most important barriers to local access is the high cost of infrastructure for competing communication services. For this reason, wireless telephony has emerged as one of the major technologies for providing alternate market access. Current market trends are towards providing high bit-rate communication services and
