The edge router and gateway also assist the host to detect the failure and quickly start the recovery process. They perform packet redirection through a lively link to the host, thus reducing or completely avoiding packet losses while the host performs the recovery mechanism to transfer the session from the failed link to the lively link. |

Adaptive envelope tracking for biasing radio frequency power amplifiers
An RF PA is designed to operate efficiently for average powers when biased at the system supply voltage, and uses an envelope tracking power supply to boost the bias voltage to maintain good efficiency at higher powers.
