On the design of an OFDM system for 60 GHz wireless LAN”, Chalmers university of technology

In the recent years, interest for broadband mobile communication in small environment has dramatically increased. Research is being conducted by several centers on very high data rate short range and/or point-to-point communication systems. In collaboration with other research facilities, we aim to implement and demonstrate the use of high-speed 60 GHz WLAN for multimedia applications. The system infrastructure should increase the throughput in a micro-cellular network at points where special services are required. The key overall requirement is a low cost per bit rate network. The following paper reoprts relevant results related to the design of an OFDM broadband air interface performed in the Communication Systems group of the Department of Signals and Systems at Chalmers University of Technology. The discussion focuses on the way an OFDM air interface has to be designed for a specic channel using simple classication criteria. This paper contains a series of results and limitations about the realization of a broadband mobile communication system for a WLAN implementation. The investigated frequency band is the unlicensed band ranging from 59 GHz to 64 GHz allocated for unlicensed devices. The 5 GHz bandwidth of this system can be seen as an unlimited bandwidth for very short range wireless communication devices. Despite the considerable implementation and channel drawbacks, such as limited power, large noise gure, limited VCO stability, shadow fading and multipath channels, we cannot ignore the huge potential of such a band on the battle for more bandwidth. Even though, specic applications requiring suc
