    摘要: Method for adapting radiofrequency signal spectrum, particularly in TETRA communications systems. The invention proposes using over-the-air signaling for communications systems according to the TETRA standard, to configure the characteristics of the radiofrequency signal, with the advantage that there is no loss of performance in data transmission speed and no need to change the type of modulation.
