Spectra is the latest version of BlueToad, 8441 TraffiCast’s Bluetooth detection technology, which can detect Bluetooth signals even when they are in a non-discoverable state – a move that can boost downstream matches by almost a factor of three. Once devices are paired – typically a mobile phone pairing with an in-car system such as a hands-free device, the Bluetooth signal is no longer discoverable by external devices – except by Spectra that is.
According to the company, trials by one authority showed that in comparison to Wi-Fi signals, Spectra matches are up to 3.3 time higher. And although Spectra increases matches by including non-discoverable Bluetooth devices, data privacy is increased as the identifying characteristics are reduced when a device is paired.
