BLE AoA locator density: what to check in a hospital designToo few BLE AoA locators is a common hospital design flaw.

Why hospitals get the densest BLE AoA designs.

Accuracy commitments for clinical workflows are usually made with a generous buffer, and that buffer ends up in locator density rather than in better commissioning. Once committed, density is hard to challenge: if the system misses its target, more locators get added at full price.

A density review against your own accuracy KPI often shows that fewer locators will meet it.

The four things that drive density.

• Clinical pathways, not the floor grid.
• Antenna orientation against ceilings, cable trays and partitions.
• The asset mix: medical equipment, beds and biomed devices need different geometry.
• Commissioning under clinical conditions, at more than one time of day.

Choosing between approaches.

Each supplier takes a different approach, from dedicated locators to existing Wi-Fi access points. We compare the options that fit your site in the survey.

Questions to ask before you accept a design.

• Will room or zone accuracy hold at peak hour?
• How quickly does a move reach the system?
• What battery drain should we expect at our update rate?
• What happens when one locator goes offline?

If the supplier can only pass the test by adding locators after the fact, the original design was a sales buffer, not an engineering design.
