RTLS Infrastructure Planning: Anchors, Power and Network
Most RTLS problems on site come from the physical set-up, not the software. Anchors or readers must be placed where they can hear the tags, powered reliably and connected to a network that carries their data. This guide covers the infrastructure checks to make before any equipment is ordered.
Key takeaways
- Place readers or anchors by coverage need, not by where cable is easy to run.
- Plan power and network points for every device before installation.
- Metal, water and tall racking change radio behaviour, so test on site.
- Document every device position for later maintenance.
Plan coverage from a floor plan, then verify on site
Start with a drawing of the area and mark the zones where you need location data. Decide how precise each zone must be, because room-level and point-level tracking need different numbers of devices. Then walk the site with a surveyor and test signal in the real environment.
Our guide to RTLS technologies compared explains how the choice of technology changes device spacing.
Metal, racking and outdoor areas
Metal shelving, vehicles, machinery and stored liquids can block or reflect signals. Tall racking may need devices at several heights. Outdoor yards bring rain, dust, heat and long distances, so devices need suitable enclosures and often mast mounting.
Power and network points for every device
Every anchor or reader needs power and a data path. Many sites use Power over Ethernet so one cable does both, with limits on cable length. Where cable is hard to run, battery, solar or wireless backhaul may be needed, each with its own upkeep.
| Item | Options to plan |
|---|---|
| Power | PoE, mains adapter, battery or solar |
| Data | Ethernet cable, Wi-Fi or other wireless link |
| Protection | Enclosure rating, surge protection and lock or tamper cover |
| Access | Safe way to reach the device for service |
Keep an installation record for maintenance
Note each device position, serial number, cable route and settings on the floor plan. When a device fails or a layout changes, this record saves hours. It also helps when you add zones later. For the full project sequence, see our RTLS implementation guide.

RTLS infrastructure: common questions
How many anchors does a site need?
It depends on area, obstacles and the accuracy you need. A site survey gives the real answer.
Can RTLS run on existing Wi-Fi?
Some systems can use Wi-Fi, but the coverage and accuracy must be tested for your use.
Is Power over Ethernet required?
No, but it often simplifies installation where cable runs are short.
Who maintains the devices?
Agree this at the start, either your team or the supplier under a service plan.
