Multiple GHz of internationally available, unlicensed spectrum
surrounding the 60 GHz carrier frequency has the ability to accommodate
high-throughput wireless communications. While the size and
availability of this free spectrum make it very attractive for wireless
applications, 60 GHz implementations must overcome many challenges. For
example, the high attenuation and directional nature of the 60 GHz
wireless channel as well as limited gain amplifiers and excessive phase
noise in 60 GHz transceivers are explicit implementation difficulties.
The challenges associated with this channel motivate commercial
deployment of short-range wireless local area networks and wireless
personal area networks. In this paper we detail design tradeoffs for
algorithms in the 60 GHz physical layer including modulation,
equalization, and space-time processing. The discussion is enhanced by
considering the limitations in circuit design, characteristics of the
effective wireless channel (including antennas), and performance
requirements to support current and next generation 60 GHz wireless
