What is indoor positioning system (IPS)?
A complete guide to what is indoor positioning system, how IPS technology works, which technology to choose, deployment steps, cost breakdown, and industry use cases — from warehouse pallet tracking to hospital asset management.
An indoor positioning system (IPS) is a network of wireless devices that determines the real-time location of assets, inventory, vehicles, and people inside buildings where GPS signals are blocked by roofs, walls, and floors. IPS uses technologies such as Bluetooth Low Energy (BLE), Ultra-Wideband (UWB), or Wi-Fi to triangulate position — typically to within 10 centimetres to 2.5 metres — without any cabling or satellite contact.
IPS vs GPS — what’s the difference?
GPS works by receiving signals from satellites orbiting the Earth. Inside a building, those signals are too weak or completely blocked. An indoor positioning system solves this by placing short-range radio transmitters called anchors throughout the building and attaching small tags to the objects you want to track. The system calculates location from signal strength, time of flight, or angle of arrival — no sky view required.
The key practical difference: GPS tells you where a truck is on a map. IPS tells you which bay of your warehouse a pallet is in, which workstation a hospital trolley is at, or which zone a forklift is currently operating in.
IPS technology comparison
Five technologies dominate industrial IPS deployments. The right choice depends on the accuracy you need, your budget, and how much infrastructure you are willing to install.
BLE Mesh / RTLS — recommended
Accuracy 1 to 2.5 metres. Range up to 100 m per anchor. Tag battery life 5 to 10 years. Low cost. Best for most warehouse monitoring and factory deployments. BLE is widely endorsed by Google and Apple and delivers reliable location even if one anchor fails due to its mesh redundancy.
BLE AoA (Angle of Arrival)
Accuracy 0.3 to 1 metre. Range up to 50 m per anchor. Tag battery life 2 to 5 years. Medium cost. Best where sub-metre precision is needed without the expense of UWB. Read more about Bluetooth AoA RTLS.
UWB (Ultra-Wideband)
Accuracy 5 to 30 centimetres. Range up to 50 m per anchor. Tag battery life 1 to 3 years. High cost. Use where centimetre precision is non-negotiable — pharmaceutical pick-and-pack, surgical instrument tracking, or precision assembly lines. Read more about UWB tracking systems.
Wi-Fi RTLS
Accuracy 3 to 15 metres. Range up to 150 m. Tag battery life 1 to 2 years. Low to medium cost. Suitable where existing Wi-Fi infrastructure is already in place and zone-level accuracy is acceptable.
Wirepas Mesh
Accuracy 1 to 5 metres. Scalable to over 1 million tags on a single network. Tag battery life 3 to 7 years. Low to medium cost. Ideal for very large facilities with thousands of tracked assets.
For most warehouse and logistics deployments, BLE Mesh strikes the best balance of cost, accuracy, and battery life. Compare RTLS solutions to find the right fit for your facility.

RFID vs BLE RTLS — which should you choose?
RFID and BLE RTLS are often considered for the same use cases but work very differently. RFID requires a handheld scanner or fixed reader to be within a few centimetres to a few metres of the tag — making it effective for checkpoint scanning but unsuitable for continuous real-time tracking across a large facility.
BLE RTLS tags broadcast continuously, so every asset’s location updates automatically on the floor map without anyone scanning anything. BLE tags also support additional sensors — temperature, humidity, shock, tilt, and panic buttons — that RFID tags typically do not offer.
The short answer: if you need to know where everything is at all times without manual scanning, BLE RTLS is the right choice. If you need a low-cost checkpoint solution at receiving docks or dispatch points, RFID may be sufficient. Read the full BLE vs RFID comparison.
Frequently asked questions: What is indoor positioning system, and its benefits
How is an indoor positioning system different from GPS?
GPS relies on line-of-sight signals from satellites, which are blocked by roofs, walls, and multi-storey structures. An IPS works entirely indoors using short-range wireless signals between tags attached to assets and anchors mounted on walls or pillars — no satellite contact needed.
What is the most accurate indoor positioning technology?
UWB delivers the highest accuracy — down to 5 to 10 centimetres — but at a higher cost and shorter tag battery life. For most warehouse and logistics applications, BLE AoA at sub-metre or BLE mesh at 1 to 2.5 metres is the better balance of accuracy, cost, and longevity.
How long does it take to deploy an indoor positioning system?
A wireless BLE RTLS system like RipplesIPS can be live in under 7 days with no cabling, no electricians, and no dedicated IT infrastructure. Wired or high-accuracy UWB systems typically take 4 to 12 weeks, depending on facility size.
How much does an indoor positioning system cost?
Wireless BLE mesh systems have the lowest total cost of ownership — no cabling, low maintenance, and pay-as-you-go subscriptions available. A starter kit is the fastest way to validate ROI before a full rollout. Contact us for a site-specific estimate.
Can an IPS integrate with SAP, Oracle, or other ERP systems?
Yes. RipplesIPS provides REST API and MQTT integration with major ERP platforms, including SAP and Oracle, as well as WMS and CMMS systems. Pre-built connectors are available for common platforms, and custom integrations can be developed on request.
What is the difference between RTLS and IPS?
The terms are often used interchangeably. RTLS emphasises continuous tracking of moving assets, while IPS can include static zone-based positioning. Most industrial deployments today are RTLS systems built on IPS infrastructure.
What is the difference between RFID and BLE RTLS?
RFID requires close-range line-of-sight scanning at checkpoints. BLE RTLS tags broadcast continuously and update location across the whole floor automatically — no manual scanning. BLE tags also support additional sensors, including temperature, shock detection, and panic buttons, which RFID typically does not.
Easily locate inventory & assets in factories and warehouses
Bluetooth low-energy blue devices have access points for constant signal strength using a mesh network for large-scale indoor positioning solutions, giving the required positioning accuracy.
Indoor location tracking is an emerging technology that is used to locate moving and stationary objects within premises such as production areas, warehouses, logistics yards, construction industries, etc. Let us look at some of the Indoor location tracking solutions for pallet tracking, inventory & asset monitoring.
There are different kinds of indoor GPS software technology available under two broad categories. First, it is a wired solution, where gateway devices are installed at designated locations on the shop floor of the manufacturing unit or hospital asset tracking, depending on the total layout of the space. Hundreds of gateway devices will need to be deployed to ensure there is full coverage to track the moving or stationary objects in logistics yards.
Bluetooth Mesh technology for indoor location tracking
The inventory pallets need to be fitted with inventory tags that communicate to one or more of the gateway devices, and using cloud-enabled application software, the end-user will be able to see the location of the object on the shop floor map. Today, highly reliable technologies are available from companies such as a mesh network that can scale to 1 million asset tracking tags on a single network.
Indoor positioning system & location accuracy
The accuracy of the location would vary between a few centimetres and 2.5 meters or higher. The more the accuracy, the higher the cost of the solution and related maintenance costs. Pallet tracking in production areas would normally require an accuracy of 2.55 square meters. Wired solutions involved extensive cabling, electrical inspections, LAN network, WiFi, or Bluetooth vs Wirepas vs Zigbee transmission protocols enabled in the factory or the warehouse, where indoor position technology is enabled using Digital Twins
Whereas, wireless solutions using a mesh technology comprise battery-operated anchors (instead of a powered gateway) and asset tags (location, movement, temperature, opening-closing, and other functions provided) typically give a location accuracy of 5 meters to depict the location within a room or a production area, such as quality control, packing or dispatch. With our software, the end customer can access order-specific information to update the production status. This is very helpful for high-tech industrial equipment manufacturers, where strict deadlines are the norm.
Bluetooth mesh RTLS Indoor tracking system
Battery life for the tags is part of the cost of ownership, which includes installation, deployment, maintenance, and the ability to expand operations as new vendor locations, departments, and inventory are added to the manufacturing line. Pallet tracking in factories & warehouses can help reduce inventory costs and improve shop floor management
The devices available in the market are a mix when it comes to environmental protection and standards. Bluetooth Low Energy is the preferred technology and is widely endorsed by industry leaders such as Google, Apple, etc. A mesh-enabled solution ensures the position network stays reliable even if one of the anchor devices fails. A battery-low alert mechanism is provided by many vendors.
Indoor RTLS tracking system in factories
Besides tracking inventory & fixed assets, the indoor location tracking with IoT dashboard can be deployed for pump motor breakdown tracking, and the movement of the workforce and contractors within the factory or warehouse shop floor. This will help in understanding the daily workflow and remove bottlenecks that will aid in productivity and elevate the morale at workplaces through greater transparency and trust.
