Abstract

The radio station has DECT circuitry for processing one or more bit streams to be transmitted over a communication channel divided into successive 10 ms radio frames each having a plurality of timeslots, each bit stream being allocated one of the timeslots in each frame. The DECT circuitry extracts bit sequences from each bit stream and modulates each of the bit sequences to form a respective radio signal burst inserted into a timeslot allocated to the bit stream in accordance with DECT formats. A clock generator, including a crystal oscillator and frequency dividers, produces a first clock signal having a frequency adapted for set the bit rate of each bit stream to 32 kbit/s, and a second clock signal having a frequency adapted for setting the bit rate within each bit sequence to 1.024 kbit/s, whereby the DECT formats remain valid while the channel has a reduced spectra bandwidth.
