Abstract:
1. A method of tuning user devices from a first upstream channel to another upstream channel based on each of the devices transmit power levels, comprising: establishing connection and registration with user devices on a first upstream channel; determining whether each of the user devices previously connected and registered is transmitting on the first upstream channel at a power level substantially equal to its maximum output power level; scanning transmission characteristics of at least one other upstream channel; selecting from the at least one other scanned upstream channels a second upstream channel that can accommodate upstream transmissions from the devices determined to be operating at substantially their respective maximum output power without adversely affecting upstream transmissions from user devices that are not operating at substantially their maximum output power level; instructing the user devices that are transmitting upstream at substantially their maximum output power level to begin transmitting upstream on the second upstream channel; and modifying transmission characteristics of the first upstream channel to provide better service to user devices still transmitting over it.
