The advantages of CDMA450 derive from the capabilities of CDMA2000 technologies that allow the provision of a broad range of voice and broadband services, and the expanded coverage afforded by a low frequency band.
- Performance: Based on CDMA2000 standards, CDMA450 provides a robust and economical platform on which to deliver a large selection of enterprise and consumer applications, as well as public services such as education, telemedicine and public safety. CDMA2000 1X is the most spectrally efficient technology to support high-quality telephony services, enabling up to 55 simultaneous voice calls in a single sector within a 1.25 MHz channel. EV-DO is a broadband technology that is capable of achieving multi-megabit per second data throughputs and low latencies to enable high-speed broadband Internet access, multicasting and delay-sensitive applications, such as voice over IP (VoIP), push-to-talk (PTT), push-to-media (PTM), video conferencing and “see what I see” (SWIS).
- Economics: The propagation characteristics of the 450 MHz band allow the provisioning of wireless services over large areas with a minimal number of base stations, creating substantial capital and operating expenditure savings.. A base station coverage area in 450 MHz is three times larger than in the 900 MHz band and 12 times larger than in the 1.8 GHz and 2.1 GHz bands, with an excellent signal-to-noise ratio. The propagation characteristics of CDMA450 also make it ideal for in-building penetration, where up to 70 percent of wireless broadband connections are made. It also enables less power consumption and higher average user data throughputs due to fewer handoffs.
