CDMA450 represents a family of CDMA2000 technologies that operate across the 410-470 MHz band.1

CDMA450 systems support all CDMA2000 standards developed by 3GPP2 and published by the TIA as TIA-EIA-IS-CDMA2000 (CDMA-MC) including: CDMA2000 1X, 1xEV-DO Release 0, Revision A, and future enhancements to these technologies. These technologies are capable of delivering voice, Internet access, multicasting and broadband data services in both rural and urban settings using fixed, limited mobility and full mobility networks.

A significant advantage of CDMA450 is that it can provide advanced telecommunication services over wide areas economically due to enhanced propagation characteristics enabled by the low frequency band. By combining the expanded range of the 450 MHz frequency band with the benefits of CDMA2000ís spectral efficiency, voice capacity, broadband data speeds, lower latency and quality of services (QoS) features, CDMA450 presents a powerful value proposition for operators and customers alike.

There is a broad range of commercially available CDMA450 devices that includes fixed wireless phones, desktop modems, machine-to-machine modules, ultra low-cost handsets and USB thumb-drive modems.

There is significant momentum behind the deployment of 450 across Africa, Asia, Europe and Latin America. It is becoming the technology of choice for providing universal access to services that will help increase social and economic prosperity.


1. The 450 MHz band includes sub-bands in the frequency ranges of 410-430 MHz, 450-470 MHz and 470-490 MHz.
