Best RTLS software in 2026: how to choose a real-time location system

There is no single best RTLS software — there is the right kind for your site. A plant that needs forklift and WIP positions to the metre, a hospital tracking pumps and beds, a venue that wants staff and visitor navigation and a warehouse that already has RFID portals are buying different things. This guide sorts real-time location systems into five kinds, gives you ten questions to ask, and is honest about where Spatial Map fits: it is a software-only map layer, not a positioning system.

What RTLS software does

A real-time location system (RTLS) answers “where is it now?” for tagged things and people inside a building. It has three layers: tags on the assets, infrastructure that hears them (anchors, gateways, readers or phones), and software — a positioning engine that turns signals into coordinates or zones, and applications that show and use them. Vendors differ in which layers they sell. Some sell all three; some only the engine; some, like Spatial Map, only the map and data layer on top. For how Spatial Map displays the positions you already collect, see RTLS software.

The five kinds of RTLS software

Most products lead with one of these, even when they touch the others:

  • Hardware-led RTLS suites — tags, anchors, a location engine and ready-made apps from one vendor, usually for manufacturing and intralogistics. Inpixon, which positions itself on industrial RTLS for the factory floor, is a well-known name here.
  • Positioning and navigation platforms — a positioning stack plus SDKs, so your own apps can show a live position and navigate; some also track assets. Navigine and Pointr are well-known names here, with different emphases.
  • Healthcare RTLS — systems built around hospital workflows: equipment location, patient and staff flow, hygiene and room status, often tied to clinical systems. Several specialist vendors focus on this market alone.
  • Software-only visualisation layers — no tags and no engine: they take positions from any RTLS, RFID or gateway and put them on a building map with other operational data. This is where Spatial Map sits.
  • DIY on GIS — positions fed into a GIS that already holds the building, for organisations with GIS staff. Esri, for example, offers ArcGIS IPS for indoor positioning alongside ArcGIS Indoors.

Ten questions to ask every RTLS vendor

Score each one on the same building and the same assets:

  • Accuracy you need — room-level, zone-level or sub-metre? Each step up usually means more infrastructure.
  • Technology — BLE, UWB, passive RFID, Wi-Fi or a mix, and why for your site?
  • Hardware lock-in — can you use tags and readers from other makers, and what happens to the data if you change vendor?
  • Infrastructure — how many anchors or gateways per floor, what power and network do they need, who installs them?
  • The map — who builds the floor plans the positions appear on, how long it takes, and who changes them when the layout moves?
  • Multi-floor — does the system know which floor a tag is on, and are stairs and lifts modelled?
  • Other data — can stock, sensors, work orders and alerts sit on the same map as positions?
  • Integration — is there a REST API, file export or event stream to get positions in and out?
  • Sharing — can people without a licence see a read-only view, and are reports exportable?
  • Pricing and exit — is the price published, what does each extra site cost, and is there a self-hosted or open-source path?

Where Spatial Map fits — and where it does not

Spatial Map is browser-based indoor mapping software for operations teams. You import a PDF or DWG floor plan, let AI Map draft walls, doors, racks, stairs and lifts for you to review, trace the rest, and stack the floors into a 3D map. Then you bind every shape to live data — RFID reads, BLE tag positions from your RTLS, sensor readings, stock from a WMS — through tables, REST sources and a per-table write API. Reports, in-app alerts, read-only share links and multi-floor wayfinding with step-free routes come from the same map, and Ask AI (beta) answers questions about a facility from its tables. Pro is $60 a month or $600 a year for up to 4 facilities after a 7-day free trial, and an open-source edition (MIT) runs on your own servers.

Spatial Map is the right kind of tool if you already have — or are buying — an RTLS, RFID portals or BLE gateways, and you want a building map your own team builds and shares, with positions next to everything else. It is the wrong kind if you need the positioning itself: it sells no tags or anchors, computes no positions from signal strength, runs no safety logic such as collision avoidance and has no SDK for a blue dot in your own app. Pick an RTLS for that layer, and check it can send positions over REST if you want Spatial Map on top.

How Spatial Map does it

Run a fair RTLS pilot in four steps

  1. 01

    Pick the assets and the accuracy

    Choose one asset type and decide whether you need its room, its zone or its exact spot.

  2. 02

    Pilot the positioning on one floor

    Tag a few dozen assets with the shortlisted hardware and log what the engine reports.

  3. 03

    Put the positions on a map

    Write them to a Spatial Map table with the write API, on a 7-day trial (no card), and link them to the floor.

  4. 04

    Score it with the people who search

    Send a read-only link to the staff who look for these assets every day and compare search times.

Choosing RTLS software — frequently asked questions

The kind built for your job. For precise positions in a plant, a hardware-led RTLS suite; for positions inside your own app, a positioning platform; for hospitals, healthcare RTLS; and for showing positions from any system on a live building map, a software-only layer such as Spatial Map.

No. Spatial Map is a map and data layer. It shows positions and zone presence reported by your RTLS engine, RFID middleware or gateways, and calculates none itself.

It depends on the site and the setup rather than the label. UWB is commonly chosen for fine-grained positions, BLE for room- or zone-level tracking at lower cost, and passive RFID for choke points such as doors and docks. Ask each vendor to prove accuracy on your floor.

Often, if each system exposes its positions over an API. Spatial Map can show several sources on one map, each written to its own table, so a UWB system on one floor and RFID portals at the docks appear together.

A useful pilot covers one floor, one asset type and the people who search for those assets, usually over a few weeks. Putting its positions on a Spatial Map floor fits in the 7-day free trial.

A 7-day free trial (up to 5 facilities, no card), then Pro at $60 a month or $600 a year for up to 4 facilities. The open-source edition is free under the MIT licence.
