Ultra Mobile Broadband Technology Overview
Michael Szu-Yuan Wang · 2008
The 3GPP2 ultra mobile broadband (UMB) system is designed for robust mobile broadband access and is optimized for high spectral efficiency and short latencies using advanced modulation, link adaptation and multi-antenna transmission techniques. The UMB system uses OFDM as the main modulation technique. The Ultra Mobile Broadband standard UMB can operate in a wide range of deployments, thereby providing WWAN operators with a lot of flexibility in optimizing their network. The design objectives of UMB are to provide performance enhancements over existing cellular systems, while maintaining competitive edge over current and emerging wireless technology.
