60GHz is well-suited for device-to-device communication and for general in-home applications due to its huge available bandwidth. However, links at this frequency are easily degraded by environmental conditions. Indeed, the poor multipath makes it necessary to maintain good LoS (Line of Sight) paths between communicating pairs of nodes. In this paper, the authors analyze the problem of link breakage and degradation in point-to-point 60GHz networks. They propose using repeaters to provide alternate paths between communicating nodes when the direct path degrades. The decision on which path to use is driven by the goal of maximizing data rate per connection as well as overall throughput in the network.
