Interference mitigation techniques in 60 GHz wireless networks

In recent years, the unlicensed 60 GHz band has motivated the computer, wireless communications, and consumer electronics industries to develop wireless personal area network and wireless local area network standards that support wireless applications with multigigabit data rates. One of the technical challenges is managing interference between networks in a dense environment. In this article we first show the problem of interference in a dense environment and evaluate and compare PHY and MAC layer interference mitigation techniques in terms of performance and the level of co-ordination required among interfering networks.
