Techniques for identifying potentially interfering wireless incumbents are disclosed. These techniques include receiving, from an electronic repository, a list of one or more wireless devices operating in a wireless communication band used by a wireless communication network. The list is selected from a plurality of wireless devices operating in the wireless communication band, based on a geographical location relating to the wireless communication network. The techniques further include scanning a plurality of radio channels relating to the wireless communication band, and identifying an interfering device for the wireless communication network based on comparing spectral data from the scanning with data in the list of one or more wireless devices.

Interference classification of wireless incumbents using spectral analysis and AFC query

Techniques for classification of wireless signals are disclosed. These techniques include receiving data describing radio frequency characteristics of a wireless network transmission environment and presenting the data for display on a graphical user interface (GUI) associated with a network device in the wireless network. The techniques further include receiving input from the GUI identifying one or more portions of the data, and training a machine learning (ML) model to classify an interferer in the wireless network transmission environment based on the identified one or more portions of the data.

Staggered Multi-User (MU) uplink in an Ambient Power (AMP) Backscatter Device (BKD) group may be provided. A transmitter AP may determine to receive uplink data from an AMP BKD group and then transmit a session initialization message to a receiver AP instructing the receiver AP to receive the uplink data from the AMP BKD group. The transmitter AP may receive an initialization response from the receiver AP indicating the receiver AP will receive the uplink data. The transmitter may transmit an AMP BKD initialization signal to the AMP BKD group indicating to the AMP BKD group to perform scattering without collisions. The transmitter AP may then transmit an excitation transmission for the AMP BKD group to perform scattering.

The present disclosure provides a dual mode antenna, comprising: a first conductive piece; and a second conductive piece, configured to electromagnetically couple with the first conductive piece through a dielectric at a second frequency to operate as a loop antenna with the first conductive piece and configured to operate independently of the first conductive piece at a first frequency to operate as a monopole antenna. The dual mode antenna can be included in an antenna array as one of a plurality of dual mode antennas coupled to a routing substrate or a reference dual mode antenna coupled to the routing substrate along with a plurality of single mode antennas coupled to the routing substrate; wherein each antenna of the plurality of dual mode antennas, the reference dual mode antenna, and the plurality of single mode antennas is arranged evenly relative to a first neighboring antenna and a second neighboring antenna.
