Abstract: System and methods for modifying streaming data based on radio frequency information is provided. As radio transceivers transition move to a shared resource or cloud model and the existing radio transceivers are split into a baseband unit and a remote radio head, radio frequency (RF) information including power levels, encoding, data rates, and bandwidth can be provided to video optimization server. The RF information can be provided more frequently to allow real-time modifications to streaming video data. Existing protocols are reactionary in nature and perceive changing channel conditions indirectly. By providing RF information from the baseband unit on a low latency channel, modifications to the video stream can be made before an impact would be noticed at the protocol level. Also, policy information can be used to influence the changes made to streaming data in addition to the RF information.
