Millimeter Waves, Millisecond Delays [PDF]
Proceedings of the 2nd ACM Workshop on Millimeter Wave Networks and Sensing Systems, 2018 Two simultaneous revolutionary changes are occurring in networking: the advent of mmWave networks and the advent of applications that require end-to-end delays of the order of a few milliseconds. mmWave is the first physical layer technology that promises huge wireless bandwidth, but with very poor reliability as a result of its vulnerability to ...
