London hospitals use mesh networking to track ventilators, vital IoT gear

Meanwhile, as lighting vendors try to morph into tech outfits, they are reminded that IT companies can be competitors as well as partners.

By Mark Halper

Late last December, when reporting on the re-emergence of smart lighting pioneer Neil Salt at a cloud computing company, we observed that one challenge facing the connected lighting industry is that lighting companies are competing with IT companies for Internet of Things (IoT) business, where the latter has the advantage of experience.

Sure, lighting companies typically team with IT companies for IoT jobs — Salt’s now-defunct Gooee did plenty of that. But the brutal reality is that luminaires are not always necessary in these matters.

The sensors and communication chips that light fixtures house to detect and convey conditions such as occupancy, climate, motion, and the like could well reside on walls, pillars, ceilings, doorways, or other parts of the physical environment.

A new case study posted by Finnish mesh-networking specialist Wirepas on its website well illustrates the point.

Wirepas often works with lighting companies. For example, LEDs Magazine recently wrote a couple of stories detailing how Finnish guest-management software and controls company Mount Kelvin is using Wirepas mesh software embedded in hotel lighting electronics to help people find each other and for lighting controls.

Likewise, Dutch smart-lighting firm Ingy typically deploys Wirepas as the engine of location and asset tracking services. Earlier this year, it agreed to a volume purchase order for 100,000 licenses to the Wirepas mesh protocol, reselling some of those licenses to Dutch luminaire maker Koopman Interlight.

Prior to the volume deal, Ingy was already a dedicated Wirepas user, having deployed it at Zone College in Doetinchem, Holland, and at University Medical Center Utrecht, where Ingy/Wirepas-enabled Koopman Interlight luminaires are helping nurses locate medical equipment.

Now, in an example similar to Ingy’s University Medical Center deployment, the new Wirepas case study highlights the work of French technology firm Apitrak at three London hospitals, where Wirepas-linked asset tracking chips and sensors are again helping medical staff to locate items such as ventilators, infusion pumps, and beds.

One big difference between the Ingy installation at Utrecht and the Apitrak setup in London is that Apitrak has not embedded the hardware into the lighting.

Rather it has mounted sensors and detectors elsewhere in the three hospitals, all of which are part of the UK’s National Health Service, and which tapped Apitrak last year to help cope with the COVID-19 pandemic.

Apitrak, based in Meylan, France, is not a lighting company. Rather it is a self-described provider of turnkey solutions to help companies track assets and manage inventory, among other functions.

Wirepas did not identify the three London hospitals, but across them, Apitrak has put tracking tags on about 3000 items across 90,000m2 and 16 floors. It has placed about 350 “anchor tags” across fixed points; the anchor tags pick up the location of the digitally-outfitted equipment.
