Indoor channel measurements of point-to-point ultra broadband short range links between 75 GHz and 110 GHz

Recently, frequencies at 60 GHz and beyond have been regaining interest for high-speed wireless communication applications (Laskar, et al., August 2007), (Piesiewicz, et al.). Decreasing technology costs on one hand and an increasing demand for higher data rates on the other hand, make a spectral shift to the millimeter wave range desirable. In the long run, the sub-millimeter wave range could be of interest, considering large available bandwidths. Emerging applications encompass uncompressed high definition video streaming and ultra fast data transfers. Especially the latter group will be primarily operated in point-to-point line of sight (LOS) short range links of several to few tens centimeters, where examples include file sharing and generic data transfers between computers and peripheral devices as well as kiosk downloading to or from a handheld, as envisaged by the IEEE 802.15.3c standardization body.
