INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Systems, methods, and devices for conducting wireless communication are provided. One method includes identifying a location of a device and obtaining spectrum usage data from a database. The spectrum usage data indicates a licensed entity licensed within an area including the location of the device to communicate across a first sub-band of frequencies within a frequency band, and one or more transmission characteristics of the transmissions of the licensed entity. The method further includes determining beam steering characteristics for wireless transmissions of the device within the frequency band using the spectrum usage data. The beam steering characteristics are determined using the transmission characteristics for the licensed entity and configured to reduce interference with the transmissions of the licensed entity within the frequency band caused by the wireless transmissions of the device. The method further includes conducting wireless transmissions over the frequency band using the beam steering characteristics. ## Claims ### Claim 1 A wireless device comprising: a circuitry configured to: identify a location of the wireless device;
