Broadband wireless access (BWA) over multi-channel multipoint distribution service (MMDS) frequency band

BWA is a hot technology that has emerged1 to satisfy the growing demand for fixed and mobile high speed data access, multimedia services, video streaming as well as teleconferencing applications. Fixed BWA preliminarily emerged to provide high speed data access for residential and small-medium business market segments, support evolution toward service integration (multimedia, voice), offer cost and performance that are competitive with wired DSL, ISDN an maximize leverage of existing cellular infrastructure. This paper describes a macro-cell/ micro-cell scenario, channel impairments, measurements, and validation performance for fixed-broadband applications in the licensed MMDS (2.5¿2.686 GHz) frequency band.
