Three PHY modes have been defined that enable data rates in excess of 5 Gb/s using the 60 GHz band. A beam-forming protocol has been defined to improve the range of communicating devices. Aggregation and block acknowledgment have been defined to improve the medium access control (MAC) efficiency at the high data rates provided for by the PHY. Keywords: 60 GHz, aggregation, beam forming, block acknowledgment, millimeter wave, uncompressed video, wireless personal area network, WPAN.Local area networks (Computer networks)StandardsMetropolitan area networks (Computer networks)StandardsLocal area networks (Computer networks)Standards.Metropolitan area networks (Computer networks)Standards.004.68WaSeSSWaSeSSDOCUMENT9910135495203321IEEE standard for information technology2574732UNINA
