Indoor positioning


It’s the ability of the Crownstones to know where someone is when carrying either a smart device or a bluetooth tag. Crownstones use the position of these smart devices through measuring Bluetooth Low Energy signals. This makes it possible for the Crownstones to react upon presence and proximity.

Requirements for indoor positioning

For Crownstones to perform indoor positioning the following is required:

 

  • We recommend one Crownstone module per 10 - 25m2
  • To have bluetooth enabled in your smartphone or to carry a bluetooth tag.

The basics

Broadcast distance

 

A Crownstone or tag can broadcast from 5m to up to 50m while still contributing to indoor positioning.

Density

 

The more Crownstones, the higher the accuracy. As a rule of thumb, two Crownstones per room is sufficient for fingerprinting (see below).

room

Wireless fingerprints

 

The fingerpint classifier can learn to localize people per room. This is often more useful than so-called trilateration and an actual position in meters (or yards).

Latency

 

More Crownstones means fewer misclassifications which means algorithms can make their decisions faster.

Location and occupancy

 

Data provided through our API can give information about the location of a user, or provide information about the occupancy per room.

Architecture



Crownstone supports at least four ways to integrate indoor localization.

smartphone

Wireless fingerprints

The algorithms run on the smartphone. The integration of the Crownstone mobile fingerprinting SDK is moderately complex. Localization can be very accurate but is labor-intensive. It requires training the algorithm per room for different smartphones.

network

In-network localization

The algorithms run on the Crownstone mesh. The integration of the Crownstone mobile iBeacon SDK is relatively simple. Localization can be less accurate. This setup requires a hub to get the localization data towards your servers. This can also localize tags (no SDK required).

iBeacons

Crownstone as iBeacons

The default localization mechanisms on a smartphone are used. No Crownstone SDK is required. The Crownstones are configured as normal iBeacons. Localization accuracy depends on the smartphone libraries your developer use.

ble tag

Centralized localization

The algorithms run on a Crownstone hub or in the cloud. Proximity information is communicated over Bluetooth mesh to a hub. Localization in real-time might be challenging (expect multiple second delays). This can also localize tags (no SDK required).

A complete solution


Along with our solutions we can also provide the following

sdk

Support for the app developers to integrate our SDKs.

hub

Hubs and servers. We can provide hardware and cloud services. We can implement an uplink towards a custom interface on your backend.

firmware

Software updates and security patches for firmware over-the-air.

Software modules

monitoring

We can provide monitoring or maintenance services about Crownstones, the Crownstone network, hubs, or other hardware if required.

dashboards

We can build dashboards if you have no application partner.

apps

We can build apps if you have no app development partner.

building

We can integrate with building automation or energy management systems.

sensor

We can directly integrate with Bluetooth sensors from any nearby Crownstone making any potentional Bluetooth sensor part of your smart building.
