Smart buildings could use indoor radar to fight Covid-19: Page 2 of 2

Indoor radar is of increasing interest for fighting Covid-19 in smart buildings.
Indoor radar and the use of power-over-ethernet systems are of increasing interest for fighting Covid-19 in smart buildings.

Last year, the imec centre in Belgium developed an 8 GHz ultra wideband (UWB) indoor radar transceiver with a power consumption under 1mW aimed at occupancy detection in smart buildings. The 40nm chip is capable of detecting even micro-movements from human respiration or heartbeats, up to a distance of 15m.

The transceiver is compliant with FCC and ETSI spectral regulations for the UWB frequency range, limiting the radiation to -41 dBm/MHz, well below the noise floor of mainstream commercial systems. This means the radar can safely be used for 24/7 people presence detection without health concerns.

 “With the new transceiver, we have an exceptional tool to create innovative smart building applications such as presence detection, people counting, fall detection, activity classification and even non-contact vital signs monitoring,” said Barend van Liempd, program manager at imec. “Together with our novel sensor fusion algorithms, our offering opens up completely new opportunities for remote sensing in various fields such as automotive, smart buildings and human-machine interaction. We invite interested companies, chip designers and application developers, for licensing of this technology or participation in the imec R&D programs.”

However being able to use the data from the radar sensors effectively is also vital says Hollfelder at Infineon. The company works with Klika Technology who provide data management systems for smart building running on the Amazon Web Service (AWS)

“It’s very important to understand how the infrastructure works,” he said. “The cloud providers are providing the infrastructure to build data collection and intelligence services, for example a database in the  cloud, so to get the insights from the data, this is part of Klika Tech’s offering.”
