ABSTRACT
ABSTRACT:
It is envisioned that revenues from data communication will surpass those from voice in wireless systems in the coming years. The thrust for developing an efficient wireless air interface for delay-tolerant packet data results in a departure from the voice-centric studies of traditional communication systems. In this light, extensive research has been conducted recently, resulting in an extension of the 3G standard, cdma2000. This extension has been approved by TIA as the IS-856 standard. IS-856 provides for an opportunistic multiple access air interface for a delay tolerant packet data only system on a separate frequency carrier. In light of the recent developments in the telecomm-unications market, carriers now want provision of packet data as well as voice on the same frequency carrier. In North America, this has prompted a further revision of the 3G standard in the form of 1xEV-DV. This talk aims to give a summary of the basic ideas behind the IS-856 standard as well as the 1xEV-DV work. The extensions of 3G in the form of IS-856 and 1xEV-DV provide a possible progression path on the way to an all-IP networked4Gair interface. A wideband 4G system, aiming to support a wide variety of services will need additional tools to further increase the spectral efficiency. Some of the possible tools providing such efficiency increase will also be discussed in this talk.
This talk is co-sponsored by the Department of Electrical and Computer Engineering at the University of Victoria
