• Healthcare, airports, retail, education, manufacturing and corporate campuses are among the industries seeing the greatest value from indoor positioning technology.

Overview

From traditional compasses to smartphone GPS, positioning technology has undergone a remarkable transformation. Digital wayfinding has become so deeply embedded in everyday life that it is difficult to imagine navigating the world without it. Today, GPS-powered outdoor navigation is an essential part of how people travel, explore and move through their daily routines.

However, GPS was never designed for indoor environments. Once a person enters a hospital, airport, shopping mall, warehouse or office tower, satellite signals become unreliable or disappear altogether. This challenge has created demand for a new category of location technology: indoor positioning.

What Is Indoor Positioning Technology?

Indoor positioning technology is the process of determining the real-time location of people, assets or mobile devices inside buildings where GPS signals are weak or unavailable.
An Indoor Positioning System (IPS) uses technologies such as Bluetooth, Wi-Fi, Ultra-Wideband (UWB), geomagnetic positioning, inertial sensors or hardware-free location intelligence algorithms to calculate a user’s position and provide location-based services.
Indoor positioning supports a wide range of applications, including:

• Indoor navigation and wayfinding
• Asset tracking
• Workforce visibility
• Visitor experiences
• Emergency response
• Space utilization analytics
• Smart building automation
• Location intelligence platforms

As organizations continue to digitize physical spaces, indoor positioning is becoming a foundational layer of modern location intelligence strategies.

Why Doesn’t GPS Work Indoors?

GPS relies on direct communication between mobile devices and satellites orbiting the Earth.

Inside buildings, walls, ceilings, steel structures and other physical obstacles weaken or block these signals. While outdoor GPS can often achieve acceptable accuracy, indoor environments require far greater precision.

For example, a 20-metre positioning error outdoors may still get someone to the correct destination. Inside a hospital, airport or shopping centre, that same error could place a person on the wrong floor, in the wrong department or outside the correct store.

This limitation has led to the development of specialized indoor positioning technologies designed specifically for complex indoor environments.

How Does Indoor Positioning Technology Work?

Indoor positioning systems determine location by analyzing signals and environmental characteristics within a building.

Most systems use one or more of the following approaches:

Technology	Typical Accuracy	Infrastructure Required
Bluetooth Low Energy (BLE)	1-5 metres	Beacons
Wi-Fi Positioning	3-15 metres	Mapping required
Geomagnetic Positioning	1-5 metres	Mapping required
Ultra-Wideband (UWB)	10-30 centimetres	Readers and tags
Inertial Navigation	Variable	Smartphone sensors
Hardware-Free Positioning	1-5 metres	No additional hardware

The system continuously analyzes signals and sensor data to estimate a user’s location as they move throughout a facility.
This real-time location information can then power navigation, asset tracking, occupancy monitoring and location analytics applications.

Current Approaches to Indoor Positioning Technology

Prior to Mapsted, there were 5 main approaches to detecting indoor location information: GPS/ cellular technology, Bluetooth beacon indoor positioning technology, geomagnetic technology, UWB indoor positioning system technology and inertial navigation technology. 

Bluetooth Low Energy (BLE)

BLE positioning uses strategically placed beacons throughout a facility. Smartphones detect nearby beacon signals and estimate location based on signal strength.
BLE has been widely adopted because it offers relatively good accuracy and can support navigation and location-based engagement. However, deployments require beacon installation, maintenance and battery replacement.

Wi-Fi Positioning

Wi-Fi positioning estimates location based on nearby access points.

Organizations can leverage existing Wi-Fi infrastructure, but accuracy is often limited and can vary significantly based on building layout and signal conditions.

Geomagnetic Positioning

Geomagnetic positioning uses the Earth’s magnetic field and building-specific magnetic signatures to determine location.

This approach reduces infrastructure requirements but can be affected by environmental changes such as renovations, equipment installations and structural modifications.

Ultra-Wideband (UWB)

UWB delivers some of the highest positioning accuracy available today.

Using specialized readers and tags, UWB can achieve accuracy measured in centimetres, making it ideal for industrial tracking applications. However, infrastructure costs can be substantial.

Inertial Navigation

Inertial navigation relies on smartphone sensors such as accelerometers and gyroscopes to estimate movement.
While useful as a complementary technology, accuracy can drift over time due to changes in user movement patterns and device orientation.

Hardware-Free Positioning

Hardware-free positioning eliminates the need for beacons, readers and other dedicated infrastructure.
Instead, advanced algorithms leverage existing signals and smartphone capabilities to determine location. This approach significantly reduces deployment complexity and maintenance costs while enabling accurate indoor navigation and analytics.

How Accurate Is Indoor Positioning Technology?

Accuracy varies depending on the technology being used, building conditions and deployment requirements.

Typical positioning accuracy ranges include:

• UWB: 10-30 centimetre
• Hardware-free positioning: 1-5 metres
• BLE: 1-5 metres
• Geomagnetic positioning: 1-5 metres
• Wi-Fi positioning: 3-15 metres

The right level of accuracy depends on the application.

For example:

• Navigation typically requires 1-5 metre accuracy.
• Asset tracking may require sub-metre accuracy.
• Occupancy monitoring can function effectively with lower accuracy thresholds.

What Does an Indoor Positioning System Cost?

The cost of an indoor positioning system depends on several factors:

• Facility size
• Accuracy requirements
• Number of users
• Infrastructure requirements
• Integration complexity
• Ongoing maintenance

Traditional beacon-based deployments often require:

• Hardware purchases
• Installation services
• Battery replacements
• Periodic calibration

UWB deployments may require:

• Readers
• Tags
• Network infrastructure
• Ongoing maintenance

Hardware-free solutions can significantly reduce deployment costs by eliminating much of the required infrastructure while accelerating implementation timelines.
