Abstract: A method and apparatus for providing radio communication with an electronic object in a local environment are disclosed. For example the method receives via a mobile endpoint device of a user at least one first digital certificate associated with the local environment from a trusted source, and a second digital certificate from the electronic device deployed in the local environment via a wireless connection. The method then authenticates the electronic device using the at least one first digital certificate and the second digital certificate.

Abstract: Disclosed herein are systems, methods, and computer-readable storage media for enabling improved cancellation of self-interference in full-duplex communications, or the transmitting and receiving of communications in a single frequency band without requiring time, frequency, or code divisions. The system estimates the signal strength and phase of a self-interference signal, generates a cancellation signal based on this estimate, then uses the cancellation signal to suppress the self-interference before sampling received analog signal. After applying the cancellation signal, the system samples and digitizes the remaining analog signal. The digitized signal is then subjected to additional digital cancellation, allowing for extraction of the desired signal.
