Wi-Fi for care settings
In a care setting the Wi-Fi shares a building with equipment that people depend on. Nurse-call, telecare, acoustic monitoring and medical devices were often installed years earlier, by other people, and the wireless design has to work around them rather than through them.
Coexistence is the design problem
What else is already in the spectrum
A care home is rarely a clean RF environment. Nurse-call and staff-attack systems, telecare and assistive technology, door and access control, acoustic or sensor-based night monitoring, wander-management systems, some medical and diagnostic equipment, DECT handsets and the building's own controls may all be operating on licence-exempt spectrum or immediately adjacent to it. Some of it is wireless in ways nobody in the building thinks of as wireless.
The first job in a care setting is therefore a full spectrum picture, not just a Wi-Fi picture: what is transmitting, on what, how often, and how close it is to the frequencies the new network needs. Adding access points at full power into a building with an existing 2.4 GHz nurse-call or telecare system, without knowing it is there, is the sort of mistake that is very hard to argue was reasonable afterwards.
Where a system's manufacturer publishes coexistence or clearance requirements, those are obtained and the design is built to meet them; where the manufacturer needs to be consulted, we would rather that conversation happens at design stage. Any change to the environment around life-safety or care-critical equipment should be agreed with the responsible provider before it is made — that is the home's decision to take, and our job is to make sure it is an informed one.
The building fabric
Care buildings run from purpose-built modern homes to converted houses to large older institutional buildings, often several of them joined together. Solid masonry, fire compartmentation, heavy fire doors that are normally closed, long corridors, and en-suite rooms with tiled wet areas all attenuate. Fire doors matter more than people expect: a corridor that measures well with the doors held open is a different corridor when the alarm system releases them.
Coverage has to be genuinely everywhere
In an office a dead spot in a store room is an annoyance. In a care setting, staff carrying handsets or care-recording devices need coverage in every resident room, every corridor, every bathroom, the day rooms, the dining room, the laundry, the kitchen, the medication room, the garden and any smoking or seating areas outside. Care records completed at the point of care only work if there is a connection at the point of care, and staff who find it does not work will go back to paper.
Three populations, three requirements
Residents want ordinary internet access on their own devices, and increasingly it is part of what a home is judged on — video calls with family are no longer a nice extra. Staff need reliable access for care systems, e-MAR, handsets and mobile devices. Visitors need something that works without a conversation at reception. These are three different requirements with three different reliability expectations, and they should not share a network without policy.
Residents are not typical users
Resident devices are frequently older, sometimes hearing-aid or assistive-technology adjacent, and the person using them may not be able to troubleshoot. An onboarding process that requires reading a code off a card and typing it accurately is not a neutral design decision in this setting. Simplicity is a functional requirement.
What we usually find
- A domestic router in the office, with range extenders added down the corridor as complaints arrived, each one halving throughput and none of them roaming properly.
- Coverage designed for staff areas only, with resident rooms — where the care actually happens — served by whatever reaches them.
- Nothing known about the other systems. Nobody on site can say what frequency the nurse-call runs on or who maintains it, and no record exists of what was installed when.
- Everything on one flat network. Resident, staff, visitor and building-services traffic sharing a single SSID and broadcast domain, with care systems competing with a visitor streaming video.
- Full transmit power everywhere, in a building with corridors that channel signal and other systems that would rather it did not.
- Gardens and outside areas with no coverage, in a setting where residents and families spend a great deal of time in them.
- No monitoring. Nobody knows the network has degraded until staff stop using the care system properly.
How we design for care
Survey the whole spectrum, and survey it discreetly
An on-site survey in a care setting includes a spectrum analysis to identify everything already transmitting, and a walk of every area staff and residents actually use — including resident rooms, with the home's permission and on the home's terms. Surveying is quiet work with a laptop and a small amount of kit; it does not require anyone to move, and we plan the route with the manager so it does not intrude on care, mealtimes or rest periods.
Design around what is already there
Channel plan and transmit power set to leave the existing systems the room they need, with positions chosen to keep clearance where a manufacturer specifies it. Where the existing equipment's requirements are unclear, we say so and recommend confirming with its provider rather than proceeding on assumption. In practice this usually means a denser design at lower power — more access points, each covering less — which is better for coexistence and better for roaming at the same time.
Coverage in every resident room and every corridor
Designed to a threshold that suits the least capable device staff carry, with continuous coverage along the routes staff walk so a handset or care-recording session does not drop between rooms. Fire doors are surveyed closed, because that is how they spend most of their life.
Separation of resident, staff, visitor and building traffic
Separate SSIDs and VLANs with policy behind them: care systems and staff devices prioritised and protected, resident and visitor access given a fair share and no more, building services isolated. Where the home's information governance or its local authority contract sets requirements about how resident traffic is handled, the design is built to meet what the home is required to do.
Simple onboarding for residents and visitors
Whatever the home wants — an open visitor network with a simple splash, a printed passphrase, a per-room credential — designed so a resident or an elderly visitor can get onto it without help, and so it does not silently expire and require the same conversation next week.
Reliability and monitoring
A care network is not a nice-to-have and it should not be discovered to be broken by a member of staff at three in the morning. Monitoring and support means degradation is seen and dealt with before it becomes an incident, and there is a number to ring that reaches people who know the building.
Working in an occupied home
Care settings are not building sites with people in them; they are people's homes, and residents may be frail, unwell, living with dementia or simply entitled to a quiet day. Everything about how we work follows from that.
- Room-by-room, agreed with the manager. Short, planned visits into resident rooms at times the home chooses, with staff present as the home requires and residents' consent handled by the home.
- Minimal noise and minimal disruption. Drilling and noisy work scheduled away from rest periods, mealtimes and activities, and kept to the shortest window that will do the job.
- Infection control. We follow the home's policy on PPE, hand hygiene, cleaning of equipment between areas and any isolation arrangements in place, and we expect to be briefed on it before we start.
- Dust, mess and reinstatement. Containment and suppression as we go, and areas returned to normal at the end of each visit rather than at the end of the project.
- Fire compartmentation respected. Every penetration through a fire-rated wall or ceiling correctly fire-stopped and recorded, which in a care building is a compliance matter and not a detail.
- Safeguarding and vetting. Identification, sign-in, supervision arrangements and DBS requirements agreed and satisfied before anyone attends.
- Accredited and insured — CHAS, Constructionline Gold, SafeContractor and TrustMark, held through The Specialist Electrical Group — with RAMS issued before work starts.
- Nothing switched off without agreement. Any work that could affect an existing system is planned with the home and its provider, in a window the home has approved.
Common questions
Will new Wi-Fi interfere with our nurse-call or telecare system?
It should not, and making sure of that is a design task rather than a hope. We survey the spectrum first to establish what is already transmitting, design the channel plan and power levels around it, and work to whatever coexistence requirements the equipment's manufacturer specifies. Where those requirements are not clear, we will tell you and recommend confirming with the system's provider before we proceed.
Can you install without disturbing residents?
We plan for it. Work is phased room by room and area by area, at times the home chooses, with noisy activity kept away from rest periods and mealtimes and confined to the shortest window that will do the job. Your infection-control and safeguarding policies apply to us and we expect to be briefed on them beforehand.
Should residents and staff be on the same network?
No. Care systems, staff devices, resident access, visitor access and building services should be separated with policy behind the separation, so that care-critical traffic is protected and a visitor streaming video in the lounge cannot degrade an e-MAR round.
Do we need coverage in the garden?
Almost always worth it. Gardens, courtyards and outside seating are heavily used in care settings by residents, families and staff, and they are the areas most often left out of an original scope. External coverage is designed and priced separately from the indoor scheme.
What happens if it stops working at two in the morning?
That is what monitoring and a support arrangement are for. Degradation should be detected and acted on before staff notice it, and when something does need attention there should be a number that reaches people who know your building. See managed Wi-Fi and support.
