MODERN multimedia applications demand higher data rates. This has been recently proven by the accelerating sales of IEEE 802.11 family WLAN hardware. Current WLANs are, however, capable of delivering only 30-100 Mb/s connection speeds, which is insufficient for future applications like wireless high-quality video conferencing. For these and many other purposes, more capacity, wirelessly, is needed. Service provided by IEEE 802.11 WLANs only fulfills the needs of normal internet users and office workers. But, bandwidth demands are still rising. In such a context, 60 GHz millimeter wave (MMW) systems constitute a very attractive solution, due to the fact that there is a several GHz unlicensed frequency range available around 60 GHz, almost worldwide[1]. This massive spectral space enables densely situated, non-interfering wireless networks to be used in the most bandwidth-starving applications of the future, in all kinds of short-range (< 1 km) wireless communication. It enables up to gigabit-scale connection speeds to be used in indoor WLAN networks or fixed wireless connections in metropolitan areas. The IEEE standards in this band are IEEE 802.11.ad for high speed WLAN and IEEE 802.15.3c for HDTV application
