Critical infrastructure

The same problem with a different layout

Tunnels, interchange hubs, airports, hospitals and large facilities. The topology and the calibration change; the system does not.

Tunnels and interchange hubs

Linear infrastructure has one advantage and one drawback. The advantage: a tunnel is effectively one-dimensional, so map matching reduces the problem to a single coordinate and transverse error stops mattering. The drawback: coverage varies section by section, and some stretches have a single access point in sight.

In those stretches the system does not invent anything: it publishes the position with its real uncertainty and flags the reading as degraded. Knowing you can only narrow it down to a two-hundred-metre section is still infinitely better than knowing nothing.

Airports

Wi-Fi coverage in a terminal is dense by definition, so the challenge is not signal: it is scale and coordination across areas run by different operators. Operations, maintenance, security and handling staff, with restricted zones and mandated traceability.

  • Large indoor footprints spanning multiple floors and levels
  • Restricted areas where traceability is a requirement, not an improvement
  • Multiple organisations operating in the same space: role-based control matters more here than anywhere else

Hospitals

Maintenance, security and porter teams spread across floors and basements, with response times that matter and particular sensitivity around processing healthcare staff data.

In healthcare the privacy conversation arrives before the technical one. Metrosafe is deployed with a purpose bounded to operational safety, minimal retention and anonymisation for anything analytical or planning-related. See how worker data is handled.

Facility management and critical logistics

Extensive sites where service teams move across halls, basements and technical galleries. Fine accuracy matters less here than response time: knowing which zone each team is in is enough to assign the next job well.

The requirement is still the same

Whatever the sector, the hard requirement does not change: Wi-Fi access points already installed and capable of enabling FTM. If they are not there, this is not the right system, and we say so before we start rather than in week eight of the pilot.
