Truly global

Based on billions of positions from global crowd-sourcing

The service uses Combain’s global database of cell-ids, buildings and LoRaWAN gateways. The database is continuously updated by our algorithms processing millions of positions from global crowd-sourcing. Your usage of the API is private and not shared with any third party.

How it works

Combain Location API helps you locate wireless connected devices. By submitting the radio signals in the proximity of a device to this geolocation API, it will respond with the most likely geographical coordinates for that device.
Combain Location API = GPS but with lower cost, lower power and also works indoor! Ideal for connected IoT and M2M devices!

The Combain Location API uses Combain’s Location Database, which is built on billions of measurements of position from GPS and radio data from beacons such as cell towers. This data is received from customers and partners, resulting in millions of new measurements every day. From all these billions of data points, we use our own modeling algorithms and a lot of server power to calculate a radio model for every beacon in the world. All these radio models become the Combain Location Database. When a location request is made to the Combain Location API, the most likely position of the device is calculated based on all these radio models that we have stored in the Combain Location Database.

Access to the Combain Location Database is through a web-based API. By sending an HTTP request that includes radio data, the latitude and longitude parameters for the most likely position of the device, and an error estimate (accuracy), a response is returned. Therefore, to use the Combain Location API service, you need access to the radio data from the device you want to locate.

Indoor location with Combain Indoor

The Combain Location Database also includes indoor positioning by indoor Wi-Fis and Bluetooth beacons. However, it’s important to note that Combain Indoor is only available in buildings for which we have received indoor positioning data. The Combain Location API positioning works only in these buildings. If you need an outdoor global Wi-Fi positioning service, we can connect you with our partner.

As GPS does not work indoors, regular crowd sourcing using only GPS is not effective. Therefore, Combain has developed a patented algorithm for indoor positioning, developed in collaboration with Lund University, that uses sensor fusion and simultaneous location and mapping (SLAM). This algorithm is available as an Android SDK that you can integrate into your Android apps. When used, it will perform both real-time positioning and indoor crowd-sourcing. Additionally, you can contribute to and improve Combain Indoor positioning in your buildings by using CPS SDK Demo or Combain API Demo apps. Please contact us for more information.

Very accurate indoor positioning with Combain Enterprise Indoor

Combain has developed new tools called Combain Enterprise Indoor for customers to survey their facilities and create very accurate indoor positioning with accurate floor detection. The positioning is based on deep learning and is more accurate compared to other methods. These tools require a special license from Combain, while the positioning is available through the Combain Location API. Please contact us for more information.
