A method of transmitting packets over radio communication links, wherein at least a first radio link and a second radio link are used for delivering flows of packets, said flows of packets containing protected packets (P IN1, P IN2) and unprotected packets (U IN1, U IN2), the method comprising: - verifying a status of propagation of the packets on the first radio link and the second radio link in order to detect presence of a faulty condition or to estimate a bit error rate; - if no faulty condition is detected or if the bit error rate is estimated to be below a minimum threshold level, transmitting a protected packet (P IN1, P IN2) over the first radio link wherein said transmission occupies a first portion of available bandwidth on the first radio link, transmitting unprotected packets (U IN1, U IN2) on at least part of the remainder of the available bandwidth of the first radio link and at least part of available bandwidth of the second radio link and not transmitting a protected packet (P IN1, P IN2) over the second radio link; the method being characterized by further comprising: - if a faulty condition is detected, such faulty condition being a signal degradation or a signal failure, or if the bit error rate is estimated to be above the minimum threshold level, transmitting a protected packet (P IN1, P IN2) over the first radio link wherein said transmission occupies a first portion of available bandwidth on the first radio link, transmitting a duplicate of the protected packet (P IN1, P IN2) over the second radio link wherein said transmission occupies a second portion of available bandwidth on the second radio link, and transmitting unprotected packets (U IN1, U IN2), on at least part of the remainder of the available bandwidth of the first radio link and at least part of the remainder of the available bandwidth of the second radio link. - verifying a status of propagation of the packets on the first radio link and the second radio link in order to detect presence of a faulty condition or to estimate a bit error rate; - if no faulty condition is detected or if the bit error rate is estimated to be below a minimum threshold level, transmitting a protected packet (P IN1, P IN2) over the first radio link wherein said transmission occupies a first portion of available bandwidth on the first radio link, transmitting unprotected packets (U IN1, U IN2) on at least part of the remainder of the available bandwidth of the first radio link and at least part of available bandwidth of the second radio link and not transmitting a protected packet (P IN1, P IN2) over the second radio link; the method being characterized by further comprising: - if a faulty condition is detected, such faulty condition being a signal degradation or a signal failure, or if the bit error rate is estimated to be above the minimum threshold level, transmitting a protected packet (P IN1, P IN2) over the first radio link wherein said transmission occupies a first portion of available bandwidth on the first radio link, transmitting a duplicate of the protected packet (P IN1, P IN2) over the second radio link wherein said transmission occupies a second portion of available bandwidth on the second radio link, and transmitting unprotected packets (U IN1, U IN2), on at least part of the remainder of the available bandwidth of the first radio link and at least part of the remainder of the available bandwidth of the second radio link.
