Communication node suitable for receiving and/or transmitting radio communications according to at least one first and one second communications protocol simultaneously

摘要

A communication node receiving and/or transmitting radio communications according to a first and a second communication protocol simultaneously. It has a first, second, respectively digital processing stage performing operations specific to the first, second protocol, respectively, operating in parallel. A first, second receiving stage, respectively, operating according to the first, second communication protocol, a transmission stage operating according to the first and second communication protocols, having a digital/analog converter converting a digital signal provided by the first or second digital processing stage into an analog signal, a modulator modulating said analog signal, an amplifier and a radiofrequency transmitter transmitting a radio frequency signal corresponding to the modulated analog signal, and a control module selecting, based on a rule and a detected event, the first or second communication protocol and commanding the transmission stage to operate selectively according to the selected protocol and no longer operate according to the non-selected protocol.

1. A communication node receiving and/or transmitting radio communications according to at least one first communication protocol and one second communication protocol different from the first protocol, comprising:
a first digital processing stage performing operations specific to the first protocol on a digital signal and a second digital processing stage performing operations specific to the second protocol on a digital signal, said digital processing stages operating in parallel, a first receiving stage operating according to the first communication protocol, a second receiving stage operating according to the second communication protocol, the first, second, respectively, receiving stage comprising a radio frequency receiver receiving a radiofrequency signal, a demodulator demodulating the radiofrequency signal received and an analog/digital converter converting the demodulated analog signal into a digital signal provided to the first, second digital processing stage, respectively, a transmission stage operating according to the first communication protocol and according to the second communication protocol, comprising a digital/analog converter converting a digital signal provided by the first digital processing stage or the second digital processing stage into an analog signal, a modulator modulating said analog signal, an amplifier and a radiofrequency transmitter transmitting a radio frequency signal corresponding to the modulated analog signal, wherein said node further includes a control module detecting the occurrence of an event, selecting as a function of a rule and of said detected event, the first communication protocol or the second communication protocol, and commanding the transmission stage to operate selectively according to the selected protocol and to no longer operate according to the non-selected protocol.
