  To meet the ever-increasing demands on higher throughput and better network
delay performance, 60 GHZ networking is proposed as a promising solution for
the next generation of wireless communications. To successfully deploy such
networks, its important to understand their performance first. However, due to
the unique fading characteristic of the 60 GHz channel, the characterization of
the corresponding service process, offered by the channel, using the
conventional methodologies may not be tractable. In this work, we provide an
alternative approach to derive a closed-form expression that characterizes the
cumulative service process of the 60 GHz channel in terms of the moment
generating function (MGF) of its instantaneous channel capacity. We then use
this expression to derive probabilistic upper bounds on the backlog and delay
that are experienced by a flow traversing this network, using results from the
MGF-based network calculus. The computed bounds are validated using simulation.
We provide numerical results for different networking scenarios and for
different traffic and channel parameters and we show that the 60 GHz wireless
network is capable of satisfying stringent quality-of-Service (QoS)
requirements, in terms of network delay and reliability. With this analysis
approach at hand, a larger scale 60 GHz network design and optimization is
possible.
