Abstract
In cellular telephone ten years ago, the challenge was to design a digital system that could achieve an order of magnitude improvement in spectral efficiency over AMPS for voice services. That challenge was met with IS-95, CDMA Cellular and will be surpassed with the improvements included in its derivatives that are now part of the IMT-2000 standard. Todayís challenge is to design a system and network that meets the ever increasing demand for wireless IP connectivity with high spectral efficiency. Voice and IP packet services impose vastly different design requirements. Voice has a very low average data rate with very stringent delay and Quality of Service (QoS) requirements. Packet Data has high data rate bursts with less stringent delay and QoS requirement. Each service should be optimized separately. For high performance wireless IP, CDMA-HDR is the answer to unleash the Internet.
