Fully Polarimetric Analysis of Wireless Connectivity for Smart Home and IoT Applications
This white paper presents a study of wireless connectivity of electronic devices in the Wi-Fi band. For accuracy, the analysis will use the full polarimetric information for each device’s antenna pattern. The study focuses on wireless connectivity between lamps and light switches in an indoor environment, with the goal to set guidelines for spacing between transmitters and receivers: wall-mounted switch boxes and ceiling-mounted lamps, as well as pairs of lamps. In general, the work flow would be similar for any type of wireless connectivity in environments such as a smart home, an industrial site, as well as streets and intersections (vehicle-to-vehicle or vehicle-to-infrastructure communication).

Automotive radars are becoming standard equipment on vehicles. Their purpose is to adjust the distance between vehicles and/or alert the driver when dangerous situations arise. Several antenna architectures are used to cover the different safety functions in complex bumper/car chassis environment where the side
