Bitcarrier sensors can be easily implemented on existing infrastructures in interurban or urban environments (e.g. on a variable message sign of a highway or on a traffic light in the street).
Within their coverage area, Bitcarrier sensors scan the Bluetooth and WIFI public frequencies of mobile devices, capture the signals emitted by such devices provided that the Bluetooth or Wi-Fi is active and they identify the type of mobile device detected (cell phones, GPS navigators, hands-free kits etc).
The signal captured by Bitcarrier sensors corresponds to an individual and distinctive identifier (unique identifier), which is correlated to every mobile device. This unique identifier does not contain any personal data at all that could link the mobile device with a particular user. However, despite the fact that the data collected by the sensor is anonymous, the sensor codifies the data originally captured before sending it to the servers, creating a new unique identifier for it and destroys the original data so that is impossible to trace the encrypted data back to the original data. The sensors send the data to the servers mainly through GPRS or 3G although they can also use other communication channels (Ethernet, Wi-Fi, serial port etc).
The database hosted in the servers receives the data sent by the servers and the platform processes such data executing Bitcarrier proprietary algorithms to generate information regarding speeds and travel times and finally it aggregates such data. The proprietary algorithms enrich the information so that it is far more useful than the original data.
The data stored in the database is delivered in real time to Bitcarrier client or to the final user through a web solution or specific applications. The web has been designed - and may be customized - so that the information shown (maps, speeds, travel times) can be easily and intuitively checked and visualized.
