I recently completed my bachelor thesis in Electrical Engineering at iNETS, Institute for Networked Systems, RWTH Aachen University
with the topic 'Empirical Characterization of a 60 GHz Transmission Link':
Wireless systems are integral part of modern day life. Nearly every household operates
a Wireless Local Area Network (WLAN) router or at least other devices enabled
with wireless communication. But while there is more and more demand for high
more data rate, current wireless communication links reach their capacity limit. The
current frequency bands useable for wireless communication are overcrowded, especially
in urban areas.
The main goal of this thesis work is to characterize a 60 GHz short range communication
link, which could potentially be a solution for satisfying the growing
throughput demands. This thesis work provides a unique characterization of actual
packet and frame based transmission. Besides private WLAN a reliable fast link
communication could also be useable for secure Point-To-Point (PTP) communication
or high speed interconnects in data centers. The 60 GHz band offers both the available
bandwidth for high speed links and the characteristics for secure PTP communication.
In this thesis work, two different setups were built to test, measure and characterize
the throughput, Bit Error Rate (BER) and distance of a high-frequency communication
link suitable for short range applications. Both setups make use of custom-made
Orthogonal Frequency-Division Multiplexing (OFDM) schemes for evaluation under
different circumstances. High data rates of over 1 Gbps while maintaining a low
BER are easily achieved, even while using only small portions of the total available
bandwidth. The applicability and effectiveness of OFDM for a 60 GHz communication
link is discussed as well as how the disadvantages of using a high frequency affect
the adequacy in different possible applications. This thesis evaluates 60 GHz links in
different application scenarios with a focus on the use of OFDM for millimeter wave
