Setting Up Infrastructure¶
When deciding on the infrastructure components, keep in mind that Navigine provides navigation algorithms, which provide different navigation accuracy. Besides that, the algorithms have different infrastructure requirements as well as provide different methods of linking the actual location to the binary map on the server. For example:
- Trilateration algorithm enables you to use the Bluetooth beacon infrastructure to link the real location to the map online. The algorithm is easy to implement - you only need to deploy beacons across the location, and then specify the beacon locations in the online map. In case of using the trilateration algorithm, navigation is performed via processing data from the mobile device and iBeacons. The algorithm relies on the exactly known locations of the iBeacons and calculates the coordinates according to the mathematical models of signal distribution.
For detailed instructions on linking locations of the beacons from real world to online map in Navigine CMS, refer to Using Trilateration.
- Fingerprinting algorithm enables you to use both - the iBeacon infrastructure and Wi-Fi infrastructure on Android devices. This algorithm performs navigation through using either data from Wi-Fi infrastructure only or through using both types of infrastructure simultaneously. To use the full capabilities of the fingerprinting algorithm, you need to implement steps described for the trilateration algorithm (above) and measure the location radiomap. The fingerprinting algorithm is more accurate if compared to trilateration as besides the emitter's location the radiomap comprises data about peculiar properties of the signal (such as reflections and dispersion).
For detailed instructions on measuring the radiomap, refer to section Measuring Radiomap of this guide. For the radiomap measurement "Golden Rules", refer to section "Golden Rules" for Radiomap Measurement.
The rest of the sections in this chapter provide complete guidelines on deploying and setting up the indoor navigation infrastructure.
