Instead of the ultrasonic token having the proximity app use htttps could we have it use Bluetooth? That way users that are non-employees (can not get on the network) that are part of the meeting can connect the app to the TP endpoint?

Thanks for your feedback.

Bluethooth is unfortunately not an option and will raise simplicity issues that we are initially trying to avoid using ultrasound. Pairing makes the user have to turn on bluethooth, locate, connect, authenticate and eventually no one is going to use it because it is too cumbersome. It also raises other concerns in terms of security. We want the app to be simple, you walk into the room and open the app and you are connected. If a company want to have the non-employees paired with the system then they should be allowed to connect to the corporate network. Some might find a solution to this if needed. Unfortunately, companies not allowing their employees handheld devices on the corporate network simply cannot use the app. There might be improvements on this in a later release so that it is not restircted to the network. Stay tuned.

Please let me know if you have further questions or suggestions :)






But couldn't Cisco program the app to automaticly connect the enpoint through bluetooth making the app have a warning of controlling bluetooth just like the microphone?

PS also what about sharing from the iOS device? (not just recieving)



Bluetooth would not have the capacity/bandwidth needed to transfer the content slides quickly enough to generate a good experience.


Best regards


Hi Ben,

sound is only used to prove proximity in our solution. All other communication to & from the endpoint is done over the local network (wifi on iPad to network port on endpoint). We continue to listen for sound to prove you're still in the room (and disconnect you if you leave), but we cannot transfer presentation data or other data in the one-directional audio stream (very low bw).

We investigated Bluetooth in the early days of this project.

  • BT travels way further than ultrasound (which is limited by the walls of the room). This means it does not give a good poitner about real proximity. In early testing with bluetooth (before we got the ultrasound to a working solution), I could pair with meeting rooms on other floors (over/under the room I was in), or even offices far away. It all depends on how the BT signal travels.
  • Since BT travels far, it won't give you good enough ensurance of being in the same room. That would require us to implement something on the endpoint menu ("allow ... to connect to the system"), and we lose the "instant" feeling and simplicity of the solution.


To your PS: Sharing has been considered and we are discussing possibilities of doing this. Not committed yet, though.




Hi Magnus
It's really a mess we don't allow to connect to the corporate network with BYOD. sadWe spend a lot of money to bring simplify to users.

So we have a dongle to share Präsentation to the screen. Inside is a small WiFi AP. Why you don't looking deeper in this solution?

Bluetooth is an other way to connect bidirectional to show and share Presentation.

looking forward Roland


Hi Roland,

The current version of Cisco Proximity requires a direct network connection between mobile device and endpoint.

We realize not not all deployments will accept this, and are discussing other solutions. We have plans to deliver proximity functionality also in other parts of the collaboration portfolio from Cisco, taking the network topology limitations of the current solution into consideration. (Future solution could for example leverage a Cisco cloud to route media from your device on 4G to the endpoint on corp network).


Hi Guys,


Is there any update to this or is it now supported over Bluetooth?


Sorry, Bluetooth for presentation transfer is not a planned feature for Cisco Proximity.
