Ask a nurse where the Wi-Fi drops, and you will usually get a precise answer: the end of the east hall, the shower room, the room next to the elevator. Staff learn the dead zones quickly and work around them. That workaround costs time, and it can mean charting delays, dropped tablet sessions and failed mobile medication scans.
Care facilities are some of the hardest places to build reliable wireless. This post explains why, and how to find and fix problems without simply buying more equipment.
Construction: older buildings often contain masonry, metal lath, fire-rated walls and tile, all of which absorb signal
Layout: long corridors with many resident rooms mean coverage must be designed room by room, not by square footage
Device mix: laptops, tablets, mobile carts, phones, nurse call systems, cameras, smart TVs and resident devices all compete for airtime
Interference: microwave ovens, neighboring networks and even some medical equipment can disrupt the signal
Roaming: staff move constantly, and devices must hand off from one access point to the next without dropping
Before touching hardware, collect specifics. Ask each unit to log where and when problems occur. A simple floor plan with marked trouble spots is enough. Note the device type, since a tablet that struggles in a hallway may point to a different cause than a laptop that works fine.
A proper survey measures signal strength, interference and capacity throughout the building, using specialized tools. It can be done on an existing network to find problems, or as a predictive design before installing new equipment. Surveying while the building is occupied gives a more realistic picture than an empty-building survey, because people and devices change conditions.
Ask the person doing the survey to report on:
Signal strength at the edges of each room, not just in the hall
Channel overlap and interference sources
Whether the network supports the speed that your busiest devices need
Roaming behavior as someone walks the length of a corridor
Access points mounted in hallways often cannot penetrate resident room walls. Moving or adding access points closer to rooms, sometimes one per few rooms, can help more than boosting power.
Too much power on too many access points creates interference with each other. Balanced channel plans and moderate power usually perform better than maximum settings.
Put staff devices, resident Wi-Fi, building systems and guest access on separate networks. This improves performance, and it protects systems that handle protected health information from devices you do not control.
Access points that are many years old may lack current standards and security features. Check whether they still receive firmware updates.
Wireless depends on the cabling and switches behind it. Slow or failing uplinks, an overloaded switch, or a weak internet connection can look like a Wi-Fi problem when the radios are fine.
Count devices, not only users. A resident wing with many personal tablets and streaming televisions can generate heavy traffic. If resident Wi-Fi shares bandwidth with clinical systems, set limits so entertainment cannot starve the EHR.
A wireless controller or cloud dashboard can show signal quality, client counts and problem devices over time. Review it monthly, and re-survey after renovations or when you add large numbers of devices. Keep a floor plan with access point locations and labels up to date so the next technician can troubleshoot quickly.
When you request quotes, ask for a written survey and a coverage map, not just a list of hardware. UnityCare IT designs and supports networks for healthcare and senior-living buildings, including wireless surveys and remediation. If your staff have a list of known dead zones, that list is a good place to begin a conversation with us.
