When wireless communication systems are to be used in an industrial setting, there are
certain requirements to be met. In compliance with such requirements, this thesis presents
a frontend for optical wireless communications which allows for data transmission over
several meters at a data rate of 100 Mbit/s. Moreover, maximum cycle times defined by
industrial standards for real time communication are adhered to.
For the transmitter, several options regarding the selection of the light source and its
driver are evaluated to choose the most promising approach. To allow for the use of
a large-area photodiode in the receiver while still satisfying bandwidth requirements, a
bootstrapping circuit is developed.
The so designed circuit is integrated into an optical wireless communication system.
Range, field of view and cycle times of this system are evaluated. Furthermore, the eye
saftey of the system is assessed.
