# Hospital equipment tracking: choosing UWB, BLE or RFID for medical asset tracking

> Wheelchairs, infusion pumps and mobile devices often go missing inside a hospital. A summary of what hospital equipment tracking is used for, how UWB, BLE, RFID and Wi-Fi differ in accuracy, and what to check before deployment.

**Key answer:** Hospital equipment tracking attaches tags to mobile medical equipment such as wheelchairs and infusion pumps and reports their location in real time through on-site anchors or the wireless network, for finding devices, inventory and maintenance scheduling. The technology choice depends on the accuracy you need: NHS England guidance says Wi-Fi locates to about 5 to 10 metres and BLE to about 1 to 5 metres, UWB reaches centimetre-level precision but usually needs new dedicated infrastructure, and RFID tags are cheap and robust but have a short read range. Before deployment, define the use and accuracy requirement first, then review existing networks, tag battery maintenance, system integration and data governance.

## What hospital equipment tracking solves

How does hospital equipment tracking work? Location tags are attached to equipment such as wheelchairs, infusion pumps and mobile monitoring devices, and on-site anchors or the wireless network report their position in real time, so nursing and clinical engineering staff can look up where a device is instead of searching ward by ward. Abroad, these systems are usually called real-time location systems (RTLS) or asset tracking.

NHS England's guidance lists medical equipment tracking as one of the main uses and describes knowing where key devices are in real time as an efficiency tool for patient care; the same foundation can support bed management, stock control and maintenance scheduling. A literature review also notes that hospitals using location tags for equipment can reduce the need for inventory counts and help deal with lost equipment. Actual results vary with the size and workflows of each hospital, so use your own inventory and search times as the baseline before deployment.

## How UWB, BLE, RFID and Wi-Fi differ in accuracy

The first selection question is how accurate it needs to be. NHS guidance summarizes four common technologies:

These figures are typical ranges for each technology; actual performance still depends on building structure, obstructions and anchor placement, and must be confirmed through a site survey and acceptance testing. For how UWB positioning works and a comparison for long-term care sites, see our article on UWB positioning and how it compares with BLE and RFID.

| Technology | Location accuracy (NHS guidance) | Strengths | Limitations |
| --- | --- | --- | --- |
| Wi-Fi | About 5 to 10 metres | Reuses existing wireless access points | Accuracy depends on access point density and obstructions; larger tags |
| BLE | About 1 to 5 metres | Small, inexpensive tags with batteries lasting years | Needs beacons; may affect existing networks |
| UWB | Centimetre-level | Better penetration of obstacles; good tag battery life | Usually needs new dedicated anchors |
| RFID | Read range within about 5 metres | Cheap, robust tags suited to harsh environments | Short range; weak response from passive tags |

## Let the use decide the accuracy requirement

Higher accuracy is not automatically better; it should match the use. If the goal is to know which floor and ward an infusion pump is on, room-level positioning with BLE or Wi-Fi is usually enough and can reuse part of the existing network. Centimetre-level technology such as UWB is only needed to tell which bed in a room a device is beside, or to automatically record devices entering and leaving specific zones.

RFID suits checkpoint situations, such as recording a device once as it passes an entrance or is returned to a fixed spot, rather than continuous tracking. Many hospitals mix approaches: general equipment is managed with room-level positioning, while high-value equipment or equipment that needs precise location uses a high-accuracy option. When mixing, confirm that location data from each technology can be viewed together on one screen.

## Planning checks before deployment

NHS guidance recommends auditing existing capability before deciding what to add. Confirm five things in order: use and coverage (which areas and which equipment), whether the existing network can support it (some wireless access points already include BLE), tag quantities and battery maintenance (including spares for loss and damage), how it integrates with hospital systems, and data security and access permissions.

If the same system is also used to locate staff or patients, notification and consent, permission tiers and data retention periods must also be handled, in consultation with the hospital's information governance and HR teams. Positioning technology is a management tool and does not replace existing equipment management policies and staff responsibilities; write down the workflows for finding equipment, inventory and maintenance first, so the system knows what to report.

## Next step: request a site assessment

If your hospital is planning equipment or staff positioning, list the equipment that most often goes missing, its main storage and use areas, and how inventory is currently done, then request a site assessment through the contact form on our website. The adoption team will explain feasible anchor placement, tag choices and system integration based on the building; costs and installation scope are explained during the assessment.

## Does hospital equipment tracking have to use UWB?

Not necessarily. If you only need to know which ward or floor a device is on, BLE or Wi-Fi is usually enough; centimetre-level technology such as UWB is only needed to tell apart bed positions or devices within the same room. Define the use and accuracy requirement first, then choose the technology.

## How often do equipment tag batteries need replacing?

It depends on the technology and reporting frequency. NHS guidance notes that low-power RFID and BLE5 tags can last from many months to several years, while Wi-Fi tags usually need more frequent charging. Battery replacement should be built into the maintenance schedule at deployment.

## Can an equipment tracking system integrate with existing hospital systems?

It can be planned, but first confirm that the positioning software can export location data and is compatible with the hospital's systems. Integration scope, data fields and timeline should be confirmed item by item during the deployment assessment.

## Does tracking equipment also end up tracking staff?

Equipment tags track devices, but if the same system is also used to locate staff or patients, permission tiers, data retention periods and notification procedures must be set in advance, in consultation with the hospital's information governance and HR teams.
