Summary:PROBLEM TO BE SOLVED: To provide methods and apparatus for an RF handoff in a multi-frequency network.SOLUTION: A method comprises: generating a handoff table that includes RF channels of current and neighboring LOIs carrying the same content as a current RF channel; detecting a handoff event; disqualifying one or more of the RF channels from the handoff table on the basis of disqualification criteria; selecting a selected RF channel from remaining RF channels in the handoff table that have not been disqualified; and performing a handoff from the current RF channel to the selected RF channel. Another method comprises: detecting a handoff event; identifying a start of a handoff time interval; determining if RSSI measurements are available at the start of the handoff time interval for RF channels carrying desired content; and performing a handoff to a selected RF channel having a greatest RSSI measurement.
