Enhancing Cellular Coverage at an Aged Care Facility
When a resident in an aged care facility presses their personal emergency response pendant, the call has to get through. When a nurse calls the duty team from the far end of a wing, the line has to hold. When a family member visits and cannot get a signal in their relative’s room, that is a small failure that adds up. Aged care facilities are exactly the kind of building where mobile coverage tends to be worst: dense construction, multiple levels, basements and plant rooms, and a layout that was designed for care, not for radio. This post covers why coverage fails in these buildings, what the fix actually looks like, and how to decide whether you need one. Where the gaps affect monitored alarms or emergency-response signalling, the back-to-base monitoring pathway is part of the same conversation.
Why cellular coverage fails in aged care buildings
Mobile signal from a carrier tower has to get through the building’s outer shell and then through every internal wall, floor, and fitting before it reaches a phone or a PERS device. Aged care facilities work against it on several fronts at once.
Construction is the first. Concrete, brick, double-glazed windows, foil-backed insulation, and steel framing all attenuate signal. The thicker and more layered the build, the less gets through. Multi-storey facilities compound it: upper floors may have line of sight to a tower while ground-floor rooms, corridors, and the basement plant room sit in a dead zone. Older buildings that have been extended over the years often have the worst patchwork, because each addition added another layer the signal has to cross.
The second is that the people who depend on coverage are not standing by a window. PERS pendants are worn in bathrooms, bedrooms, and corridors. Nurses move through the building. Residents take calls in their rooms, often on the side of the building facing away from the nearest tower. The places where coverage matters most are usually the places it is weakest.
The third is that nobody notices until it matters. A facility can run for years with patchy coverage that staff have quietly worked around, until a PERS call drops, or a family complaint escalates, or a monitored-alarm signalling path turns out to depend on a cellular link that barely works. By then it is an incident, not a maintenance item.
What the fix looks like
The fix is an in-building cellular coverage system: equipment that captures the carrier’s signal outside the building, amplifies it, and redistributes it inside where it is needed. The shape of the system depends on the building and the level of coverage required.
Carrier-approved signal repeaters. For small to mid-size facilities, a carrier-approved cellular repeater (such as a Cel-Fi GO unit) captures signal through a donor antenna mounted where reception is strongest, amplifies it, and re-broadcasts it through internal antennas placed against a coverage plan. Multiple units cover larger or more complex layouts. These devices are carrier-approved for use in Australia; unapproved boosters are illegal and can interfere with the carrier network, so the device choice is not a free-for-all.
Distributed antenna systems. For large multi-level campuses, a distributed antenna system (DAS) runs a cabled network of antennas through the building, fed from a head-end. DAS is more involved and more expensive, but it scales to coverage levels and building sizes that repeaters cannot reach.
Hybrid and staged approaches. Many facilities do not need a campus-wide DAS. A handful of repeater units covering the wings where PERS pendants are worn, the corridors staff move through, and the plant room where signalling equipment lives is often enough, and it can be staged building-by-building or wing-by-wing.
Whatever the system, the donor-antenna placement, the internal antenna positions, and the cabling between them are designed against a coverage survey, not guessed.

What to check before scoping a system
A few questions shape the project and the cost.
Which carrier (or carriers) do you need to cover? PERS providers, staff phones, and residents may not all be on the same network. Some repeaters cover one carrier per unit; multi-carrier coverage means more equipment. Confirm which networks actually need to work in the building before scoping.
Where does coverage have to reach? A coverage survey walks the building with a signal meter and maps the dead zones against where they matter: resident rooms, bathrooms, corridors, the plant room where alarm signalling lives, the basement, the car park. The survey, not a brochure, defines the antenna count and placement.
What does the building allow? Heritage finishes, fire-rated walls and ceilings, and shared risers all constrain where cable can run. Where cabling a path would mean touching a fire-rated surface, the design works around it.
Does monitored signalling depend on cellular? If your monitored alarm or PERS base station signals over a cellular link, that link’s reliability is part of the coverage plan, not a separate question. A coverage system that fixes resident-room signal but leaves the plant room weak has missed the point. Our modern monitored alarm systems post covers how the signalling pathway fits into the wider monitored-response picture.
How to decide whether you need one
Three questions will tell most aged care operators whether this is worth acting on.
- Have PERS calls, staff calls, or monitored signalling ever failed or been slow because of signal? If yes, even once, that is the decision made. Resident-safety signalling is not a place to tolerate “usually works”.
- Are there known dead zones in resident areas? If staff have a mental map of “you won’t get a signal in that wing” or “the basement is a black hole”, a coverage survey will turn that map into a plan.
- Is the building due for any other works? A refurbishment, a wing extension, or a new build is the cheapest time to design coverage in, rather than retrofitting it later. If works are planned, the coverage question belongs in the scope now.
If none of those apply, the building may be fine as it is. If any do, a coverage survey is the low-commitment next step: it tells you the size of the problem before you commit to a fix.
Worked example: Aveo Peninsula Gardens
Aveo Peninsula Gardens, a residential community for older adults on the Gold Coast, had significant cellular coverage gaps across 60 apartments over four levels. With residents relying on PERS devices for safety, patchy coverage was a resident-safety issue, not just an inconvenience.
Metwide conducted a coverage survey of the building, then deployed Cel-Fi GO G41 units, placing donor antennas where the external signal was strongest and running Cat6 UTP cabling to internal antennas positioned to cover the apartments and common areas. Each unit was sited against the survey rather than guessed, so the amplified signal reached the rooms and corridors where PERS pendants are actually worn.
The result was reliable cellular coverage across the facility: PERS devices operate without the signal dropping out, staff communicate without dead zones, and residents and families stay connected. For an aged care operator, that is the difference between a system that works in the demo and one that works at 3 AM in a ground-floor bathroom.
What a Metwide coverage assessment looks like
An engineer from our field team walks the facility with a signal meter, maps the dead zones against where coverage matters (resident rooms, corridors, plant rooms, basement, car park), and confirms which carriers need to work in the building. You get back a written plan covering which areas need coverage, the equipment and antenna positions to achieve it, what cabling is needed and where it can run given fire-rated and heritage constraints, costs broken down by area, and a recommended rollout order so the highest-risk areas (PERS-critical wings, signalling plant rooms) come first. From there you decide what to do next, on your timeline.
