BlueVia is a traffic beacon dedicated to travel time measurements systems and dedicated to origin-destination analysis. BlueVia detects the MAC address of any Bluetooth or Wifi device which is located in the vicinity. BlueVia converts this address into an anonymous identifier before sending this identifier to a server. With a reach exceeding 100m and an omnidirectional antenna, BlueVia collects a very important part of the road traffic thanks to an ultra fast scanning algorithm. BlueVia is natively equipped with GPRS connectivity and can be feeded through a small solar panel.
