Why Gigabit Ethernet (GigE)?
LANs are rapidly converging on GigE as the basic server backbone speed. In order to extend LAN backbones between buildings, GigE links are required in order to prevent the inter-building connection from becoming the performance bottleneck for the entire client base located in the building that is remote from the physical servers. Not only are the backbone connections converging on GigE, but also GigE is quickly becoming the interface of choice for client PCs. Why 60 GHz? 60GHz is license-free spectrum with most of the benefits of licensed spectrum. While anyone can deploy a 60GHz link without permits, paperwork, public notices nor license fees, narrow antenna beamwidths and oxygen absorption phenomena minimize the potential for interference between users. What about security? The GE60 naturally provides a high degree of physical link security. Oxygen absorption prevents reception of signals beyond one kilometer of a transmitter. The very narrow antenna beamwidth and very low antenna si
