Claim 13:
14. An extension system for extending the coverage of a Wi-Fi access point, comprising:
an extension device; and
at least one repeating device, which comprises:
a first receiver configured to receive, via a wired connection connectable to the extension device for extending the Wi-Fi access point, a digital signal resulting from an analogue-digital conversion of an analogue signal from a power division of a signal intended to be transmitted by said Wi-Fi access point around a first predetermined frequency carrier so as to deliver a first Wi-Fi signal;
a digital-analogue converter configured to convert the digital signal received via said wired connection into an analogue signal; and
a radio retransmitter configured to transmit the analogue signal supplied by the digital-analogue converter around said first predetermined frequency carrier, so as to deliver a second Wi-Fi signal substantially identical to the first Wi-Fi signal;

said extension device comprising:
an analogue-digital converter configured to convert into the digital signal the analogue signal from the power division of the signal to be transmitted by said Wi-Fi access point around the first predetermined frequency carrier so as to deliver the first Wi-Fi signal; and
a transmitter configured to transmit said digital signal to said at least one repeating device via the wired connection;

wherein the at least one repeating device and/or the extension device comprises an offset module to offset the second Wi-Fi signal compared to the first Wi-Fi signal.
