System
- Use beacons mounted on stationary objects within a room to allow user supplied devices to triangulate their rough position inside the room
- The users may share their location via various means.
- XMPP
- complex
- relies on external infrastructure eventually
- robust against network topology traversals (NAT/Firewall)
- Multicast
- simple
- not robust when traversing NATs
- XMPP
- Useful for a conference hall or the like, where an area is large enough to prevent finding ones way or friends easily.
testing guest captcha
Hardware
SOCs
Front End/BT modules
- just as expensive as SOCs
Software
Phone App
Android
iThing
Firmware
- bit-bang BTLE library code for reference
Beacon
- Similar use cases
- Beacon tagging - tags beacon to allow device to find the tagged item
- iBeacon - proprietary implementation
- Beacon tagging - tags beacon to allow device to find the tagged item
- Use Proximity Sensing Profile (PXP/FMP) to let user devices know where and roughly how far they are from the beacons.
