@ARTICLE{Janisz_Konrad_Remote_2018, author={Janisz, Konrad and Stępień, Jacek and Odrobina, Szczepan}, volume={vol. 64}, number={No 2}, journal={International Journal of Electronics and Telecommunications}, howpublished={online}, year={2018}, publisher={Polish Academy of Sciences Committee of Electronics and Telecommunications}, abstract={This paper presents an experimental system for remote communication between road users and traffic signs. Implemented solution consists of two modules: a transmitter (traffic sign), including novel system for remote waking-up by the passing vehicle with use of the quasi-passive (biased) diode detector circuit, and a receiver (vehicle), which is responsible for wake-up signaling and interpreting received messages. Both modules use Wi-Fi protocol operating in 2.4 GHz ISM band for sending data, and OOK signaling in 868 MHZ ISM band for sending wake-up signals. The paper provides theoretical analysis, description of design challenges and chosen solutions, and finally, laboratory measurements as well as the results of tests conducted in the systems’ target environment with a moving vehicle, confirming correct operation of the system.}, type={Artykuły / Articles}, title={Remote System for Reading Traffic Signs and Information}, URL={http://www.czasopisma.pan.pl/Content/103855/PDF/33_1060-4320-1-PB.pdf}, doi={10.24425/119374}, keywords={systems, automotive electronics, telecommunications, traffic signs reading, Internet of Things}, }
