The Third Generation Partnership Project (3GPP) has begun charting the long-term evolution of 3G to ensure the competitiveness of 3G technology during the next 10 years and beyond. The fundamental aims of this evolution - to further improve service provisioning and reduce user and operator costs - will be met through improved coverage and system capacity and by improving data rates and reducing latency. The authors describe technologies that promise to provide these improvements, including orthogonal frequency-division multiplexing (OFDM), multi-antenna solutions, evolved quality-of-service (QoS) and link-layer concepts, and an evolved system architecture. The authors also present the results of a performance evaluation which confirms that the long-term requirements can indeed be fulfilled.
