In existing Handsfree carkit solutions, only one party is often allowed to talk at each time (half-duplex communication) to eliminate accoustic echoes. Although there are now more solutions that allows both parties to talk at the same time (full-duplex communication), there are still some compromise in terms of double talk quality. Also, when using the handsfree carkit in noisy environments (e.g. engine noise, car audio, wind noise, etc), the speech is often barely audible if noise suppression techniques are not implemented. If noise suppression techniques are implemented, the speech quality is usually greatly compromised.

In BITwave, we have developed both a Bluetooth and analog handsfree carkit solution that enable drivers to receive and answer calls when they are on the road. With our leading edge acoustic echo cancellation and microphone array technology, we provide full duplex, echo free communications. Furthermore, with our leading edge noise suppression technology, all environment noise are suppressed and only crystal clear speech is transmitted to the other party.
