The 60 GHz wireless networks enable multi-Gbps local communications. With opportunities, however, there are many challenges because the physical wave characteristics of the 60 GHz band are quite different from those of the currently used 2.4 GHz and 5 GHz ISM bands. Moreover, there are many hot issues associated with the MAC (Medium Access Control) layer as the directional MAC protocols proposed for 2.4 GHz and 5 GHz cannot be directly implemented on the 60 GHz frequency because of different characteristics of the millimeter waves. However, no review on MAC for 60 GHz wireless networks has been reported in the literature. In this paper, we comparatively review standards and protocols of MAC in 60 GHz wireless networks for multi-Gbps communications. Opportunities and challenges are also discussed.
