Abstract: Wireless technologies operating in the unlicensed ISM (Industrial Scientific and Medical) bands are omnipresent. Indeed, with the expansion of the Internet of Things, plenty of applications are being developed on devices that use the 868.3 - 868.8 MHz ISM band. This expansion has an impact on existing technologies operating at the same frequencies. This paper focuses on the impact of IoT networks on a special use case deployed in smart cities which is the connected traffic light for visually impaired pedestrians. A connected traffic light is equipped with a radio receiver that operates at 868.3MHz frequency. It allows pedestrians to query the state of the traffic light using a handheld remote control. When the latter is pressed, a generated radio message will activate a sound beacon that tells the state of the traffic light. In some cases, when the traffic light is not optimally deployed or when it suffers from interference, the connection with the remote control cannot be establishe d. In this paper, we investigate, using a detailed simulation analysis, the impact of interfering IoT devices and antenna types used on the receiver module of the traffic light on the quality of the radio links.
