Real time location API update interval settings

We have implemented indoor wayfinding and use the /v1/location/clients/ API for user location (blue dot). The wayfinding app query for its location every 2 seconds, but we are experiencing a big variation in the update interval of a user location returned from the MSE.

Despite moving across several APs the MSE returns the same coordinates for sometimes up to 80 seconds. The interval for an updated location varies from 4 to 80 seconds.

I'm looking for help on setting up the interval of individual client location calculations on the MSE.

 

Thanks!

 

Details:

  • MSE 8.0.140.9
  • FastLocate: Enabled
  • APs: 2702 + 3802
  • The app queries through a proxy server in DMZ.

 

Proxy log snip:

The age of the position returned for MSE request 'https://172.18.1.112/api/contextaware/v1/location/clients/192.168.118.89' is: 85.435 seconds|...

Re: Real time location API update interval settings

The update is dependent on the client actually talking and therefore when MSE updates it.

Does the WLC have fast locate enabled? Without this you are only tracking beacons not data frames from the client

Wireless clients can decide to when to transmit and can be anywhere between 1 second and 2 minutes.
