Adaptive point-to-point microwave radio system
First Claim
1. Method for transmitting signals via a point-to-point microwave radio link from a transmitting unit to a receiving unit of a point-to-point microwave radio system, wherein said signals comprise packets, wherein said packets are classified before transmission based on at least one quality of service parameter associated to each packet, and wherein said signals are modulated by said transmitting unit for transmission with a real-time adaptive modulation, which modulation is adapted based on the current traffic amount, on signal quality measurements indicative of the propagation conditions on the radio link, and on the classification of packets comprised in the signals.

Abstract
The invention relates to a method for transmitting signals via a point-to-point microwave radio link from a transmitting unit 1, 2 to a receiving unit 2, 1 of a point-to-point microwave radio system, which signals comprise packets. In order to improve the efficiency on the radio link, it is proposed that in a first step, the packets are classified before transmission based on at least one quality of service parameter assigned to each packet. In a second step, the signals are modulated by the transmitting unit 1, 2 for transmission with a real-time adaptive modulation. This modulation is adapted based on the current traffic amount, on signal quality measurements indicative of the propagation conditions on the radio link, and on the classification of packets comprised in the signals. The invention relates equally to such a point-to-point microwave radio system comprising two units 1, 2 between which signals are to be transmitted, and to transmitting unit 1, 2 for such a system.
