In some embodiments, the semantic-less wireless repeater may identify and authenticate transmissions. After authenticating the transmission, PHY layer metrics, such as error magnitude from IQ sample(s), are used to decide whether or not a retransmission is appropriate and necessary. Upon deciding that a retransmission will occur, some embodiments may launder the signal to remove any jamming and/or interference that may have been introduced during the transmission.

FIG. 1 illustrates an RF repeater configured for semantic-less retransmissions in accordance with some embodiments. The RF repeater may include receiver circuitry 102 to demodulate the received RF signal, authentication circuitry 104 to authenticate the received RF signal based on one or more authentication features 114 and retransmission determination circuitry 106 to determine whether or not to retransmit the received RF signal based on one or more retransmission features 116. The RF repeater may also include remodulation and retransmission circuitry 108 to remodulate and retransmit the received RF signal. These embodiments are described in more detail below.

The RF repeater may also include one or more antennas. The antennas may comprise one or more directional or omnidirectional antennas, including, for example, dipole antennas, monopole antennas, patch antennas, loop antennas, microstrip antennas or other types of antennas suitable for transmission of RF signals. In some multiple-input multiple-output (MIMO) embodiments, the antennas may be effectively separated to take advantage of spatial diversity and the different channel characteristics that may result.
