Patent number: 9882627Abstract: A repeater configured to dynamically affect the gain level of the repeater in response to the input signal power level over time. The repeater system includes a gain hold processor executing a gain hold algorithm. The gain hold algorithm preempts a large up-step in signal power level to follow a large down-step in signal power level. After a large up-step in input signal is detected, the system holds the gain level in response to a drop in input signal level after the large up-step. The gain is held at the level set by the large burst of input signal power to the repeater. In response to a larger up-step in signal power level, the system will lower the gain. In response to a large down-step in signal power after the larger up-step in signal power level, the system will hold the gain level of the repeater. During a prolonged low-power level or zero power signal at the input of the repeater, the system will slowly raise the gain level of the repeater over time.Type: GrantFiled: April 6, 2016Date of Patent: January 30, 2018Assignee: Nextivity, Inc.Inventor: Ian Riphagen
