1. A wireless power receiver apparatus comprising:
- means for entering a listening mode to actively listen for connection invitations broadcast by wireless power transmission systems in a wireless power delivery environment, the wireless power transmission systems each including multiple antennas configured to transmit coherent wireless power signals for delivery to wireless power receiver apparatuses;
means for receiving, during the listening mode, the connection invitations;
means for processing the connection invitations to identify attributes associated with the wireless power transmission systems;
means for generating or updating one or more scores associated with the wireless power transmission systems based on the corresponding attributes; and
means for establishing a connection with at least one of the wireless power transmission systems based on the generated or updated one or more scores.
