    Content: High-precision sensor networks and localization systems require precise time and frequency synchronization. In this paper, we present a novel high-precision frequency synchronization approach for wireless network devices. It adapts the local oscillator frequency of a receiver to the frequency of a transmitter and can be integrated into existing wireless communication systems. The measurement of frequency differences as well as the frequency adjustment is realized in Field Programmable Gate Arrays (FPGAs). Using a 60 GHz wireless experimental setup, the receiver clock is aligned to the transmitter clock with a precision of 37 picoseconds.

    Content: This paper gives an overview of frequency regulation, standardization, and applications of 60 GHz communication systems. Based on forecasted developments of mobile IP traffic, the motivation for investigating circuits, and systems for the 60 GHz band is underlined. Some physical properties of 60 GHz radio waves are outlined and implications on potential applications are sketched. The current international and European frequency regulation aspects are presented. The main parameters of three different international standards are summarized and compared with each other. Details of channel spacing and channel bonding are given. Based on the investigation of different applications, the main system requirements are derived. Finally, some information on protocol issues and system integration aspects are given.
