Recent Trend of Millimeter-Wave Access Systems

Abstract

This paper describes the recent trend of millimeter-wave wireless access systems which utilize the advantages of millimeter-waves. The fixed wireless access systems are first discussed and newly developed testbed at Yokosuka city area for broadband transmission is introduced. Then three promising short distance wireless access systems using 60-GHz frequency are discussed. The first one is on video transmission in the house, the second on vertically -connected link for the apartment infrastructure, and the third on wireless personal area ad-hoc system. Lastly millimeter-wave self-heterodyne transmission method is briefly introduce which can decrease the complex and cost of millimeter-wave local oscillators.
