Abstract
The short range radio receiver for motor vehicle data comprises antenna circuits (1–4) connected to a unit (10–15) for processing a carrier in a plurality of specific frequency bands which is modulated by a data signal, the unit (10–15) comprising frequency-transposing circuits (11, 23–28) connected to demodulation circuits (13) supplying the demodulated data, and frequency discrimination circuits (21, 22) are provided, connected to the antenna circuits (1–4), to determine respective reception levels within the bands in order to compare them with each other and to control the frequency transposing circuits (11, 23–28) depending on the result of the comparison.
