Air You Can Trust<\/h1>\n\n\n\n

University of La Laguna (est. 1792).<\/strong> Canary Islands. Spain.<\/strong><\/p>\n\n\n\n

\n\n\n\n

Protecting university spaces from the invisible threat of radon<\/h2>\n\n\n\n

How the University of La Laguna deployed a network of radon and indoor-air-quality sensors across 70 academic and administrative areas \u2014 without a single new cable, without one additional network device, and without expanding its attack surface.<\/p>\n\n\n\n

\n\n\n\n

Radon is a naturally occurring radioactive gas \u2014 colourless and odourless \u2014 that accumulates in enclosed spaces and is the second leading cause of lung cancer after tobacco. In the Canary Islands, the volcanic nature of the subsoil pushes potential exposure well above the national average, and the municipality of San Crist\u00f3bal de La Laguna is classified as Zone 2 \u2014 the highest protection category \u2014 under both European (Directive 2013\/59\/Euratom<\/em>) and Spanish regulations (CTE DB-HS6, RD 732\/2019<\/em>).<\/p>\n\n\n\n

The University of La Laguna \u2014 with close to 30,000 people across students, faculty, and staff, and numerous buildings where teaching and administrative activity also takes place on ground floors \u2014 chose to go beyond minimum compliance: to put in place a permanent, real-time monitoring infrastructure without disrupting academic activity and without opening new operational fronts on its corporate network.<\/p>\n\n\n\n

\n\n\n\n

An IoT network on top of the existing WLAN<\/h2>\n\n\n\n

The solution leverages the HPE Aruba<\/strong> WLAN infrastructure already in place across the campus. Thanks to the technology partnership between HPE Aruba<\/strong> and the EnOcean Alliance<\/strong>, plugging an EnOcean USB Gateway into each access point’s USB port is enough to turn it into an 868 MHz IoT coverage cell. The WLAN serves solely as an encrypted transport for the telemetry \u2014 it does not share spectrum with the user Wi-Fi network and does not process the IoT data on its own.<\/p>\n\n\n\n

Two Deuta Controls sensors have been installed in each area: the EnoSense Radon \u2014 the world’s first radon sensor with an 868 MHz EnOcean radio \u2014 and the EnoSense CO2, self-powered through Energy Harvesting (no cells, no batteries, no wiring). Telemetry flows through a secure WSS tunnel to the iWIP DATZN\u00ae<\/strong> IoT management platform, a member of the EnOcean Alliance<\/strong>, where it is centrally monitored, visualised and reported.<\/p>\n\n\n
