Abstract
Methods and apparatus for RF handoff in a multi-frequency network. A method includes generating a handoff table that comprises RF channels of current and neighboring local operations infrastructures (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 based on 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 includes 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.
