Wheere, the revolutionary indoor geolocation technology

At Wheere, we've revolutionized indoor geolocation with an innovative, patented approach that goes beyond the limits of traditional systems. We offer an unrivalled solution for precise positioning, both inside and outside buildings.

What is Wheere's positioning technology?

A solution that overcomes the limitations of traditional systems

Traditional geolocation systems, such as GPS or Ultra Wide Band (UWB), rely on the transmission of modulated waves to measure the distance between transmitters and receivers, and thus deduce a position. These approaches require a wide bandwidth, forcing the transmission of high-frequency waves, which do not penetrate walls and are therefore incompatible with indoor use.

Wheere innovation
Indoor geolocation reinvented

Wheere has abandoned traditional binary coding in favor of an innovative method based on two main elements:

The emission of low-frequency waves

Our systems emit low-frequency waves capable of penetrating walls, guaranteeing geolocation coverage inside buildings. Specifically, we transmit on fine sub-bands in the following frequency ranges: 66-88 and 136-174 MHz.

The Wheere algorithm for sub-metric precision

Our solution measures the phase of received signals to deduce the distance between transmitter (Gateway) and receiver (Module). The key point indoors is to separate the direct path from the multiple bounces and diffractions. This is where the effectiveness of the Wheere algorithm lies.

How does our geolocation technology work?

Our current solution is based on the installation of transmitter stations, known as gateways. Here's how it works:

1
Gateway installation
Four gateways are placed at the ends of a one-square-kilometre area and connected to antennas on high ground.
2
Tracker equipment
Each person or object to be geolocated wears a "tracker" equipped with the Wheere electronic module. This module receives signals from the gateways and performs the necessary calculations.
3
Precise indoor and outdoor geolocation
Trackers within the coverage area of the four gateways are located with an accuracy of 80 cm, both inside and outside buildings.
4
Data upload
Position data is available locally on the tracker. It can be stored or transmitted in real time by conventional means (BLE, 4G, LoRa, etc.).

What are the different types of geolocation?

There are six main families of geolocation technologies, each adapted to specific contexts and needs:

GNSS

GNSS is based on the use of satellites to provide highly accurate global positioning information. GNSS systems include GPS (USA), GLONASS (Russia), Galileo (Europe) and Beidou (China). Although extremely accurate outdoors, this technology is not effective indoors or in dense urban environments, where signals are blocked or reflected by buildings.

Public networks

Public networks use existing transmitters such as WiFi, 4G/5G and LoRaWAN. The principle is to measure the signal strength received from a known public transmitter and deduce a location zone around it. This method is practical because it uses infrastructure already in place, but it can be less accurate than other technologies due to the variability of signals.

Mesh systems

Mesh systems use a network of interconnected nodes, where each node represents a device capable of receiving and transmitting signals. These nodes communicate with each other to determine the position of an object or tracker. The limitation of this model lies in the dependence of each object in the mesh on the presence of other objects nearby. What's more, geolocation accuracy can be compromised if the location of other reference objects is itself inaccurate.

Local radio technologies

Local radio technologies involve the deployment of anchors such as RFID, Bluetooth and UWB, which act as reference points for a tracker or connected object. These technologies use radio signals to determine position based on signal strength or time of flight between transmitters and receivers. They are effective in indoor environments, but require transmitters to be installed in every room.

Inertial systems

Inertial systems use inertial measurement units ranging from simple three-axis accelerometers to ten-axis IMUs (accelerometers, gyroscopes, barometers and magnetometers). By combining these measurements, they provide displacement information that can be transformed into position by integration or filtering. However, position drifts over time and needs to be recalibrated with other absolute positioning solutions to maintain accuracy.

Optical technologies

Optical geolocation technologies use cameras and optical sensors to determine position based on visual cues. These systems can be highly accurate, and are used in environments where many distinctive visual details are available, such as in warehouses or factories. However, their effectiveness can be reduced in low-light conditions or where there are visual obstructions.

However, their effectiveness can be reduced in low-light conditions or where there are visual obstructions.

The choice of indoor geolocation technology depends on the specific needs of each entity, particularly in terms of accuracy, cost and existing infrastructure:

  • Inertial is the easiest to set up, as it requires very little installation, but its accuracy drifts over time.
  • UWB is best suited to high-precision applications, while Bluetooth and Wi-Fi offer more economical and easy-to-deploy solutions.
  • GPS remains limited to outdoor environments due to its poor indoor performance.

As for Wheere, it's the only technology that can penetrate obstacles and cover an entire site with just four antennas, with an accuracy of less than one meter.

It is essential to carefully assess the requirements of each project in order to select the most suitable technology.
