Abstract
A method for a hitless handover in a hitless handover of communications in a Radio Frequency (RF) network is disclosed. The method including: providing a terminal comprising a first demodulator, a second demodulator and a phased array antenna; receiving communications via a first outroute signal in a first coverage area with the phased array antenna over a first outroute and processed by the first demodulator; transmitting a first inroute signal in the first coverage area with the phased array antenna over a first inroute; determining that the first outroute is setting when the terminal is imminently leaving the first coverage area and that a second outroute is rising when the terminal is entering a second coverage area; acquiring a second outroute signal in a second coverage area with the phased array antenna over the second outroute and processed by the second demodulator; sending a request to receive the communications over the second outroute, while the terminal is disposed in an overlap of the first coverage area and the second coverage area; establishing communications via the second outroute; and handing over communications from the first outroute to the second outroute whil…
