Being a Faraday cage, the car doesn't offer the best environment to make a phone call. The loss of signal is significant. The quality of the calls is often poor. With Laird's automotive Best Reception Solution the signal loss is reduced to zero. The quality of the phone calls is outstanding. The car driver has the same data and voice transmission quality as outside the vehicle.

Best mobile reception with patented high frequency technology


Often the antenna of a mobile phone is not able to ensure the required reception inside the vehicle, because the vehicle body shields the radio signal. The loss of signal in a midclass vehicle is such grave that just 1/16 to 1/32 of the signal generated by a phone will penetrate outside the vehicle. Laird solves this issue fully compensating this lost by improving the quality of the calls. The motorist inside the vehicle will have the same reception‘s quality as who is phoning outside the vehicle.


Laird‘s automotive Best Reception Solution is based on the co-work of the Antenna Coupling with a MultiBand Compenser®. The Laird antenna coupling picks the telephone signal via near-field coupling and transmits it via cable through the MultiBand Compenser® to the exterior vehicle antenna.

The Laird MultiBand Compenser® compensates for signal loss, thus ensuring outstanding data and voice transmission, improving the quality of the calls. The overall system gain is zero (0dB).


Laird Best Reception System guarantees outstanding quality of the calls made inside the vehicle.
By better audio quality; higher data rates; less radiation; lower power usage; as a system without the Laird technology inside.
