Patent ID: 7768974

Claim:
A method for generating pilot beacons for hard handoff over a border from a first environment to a second environment using spread spectrum technology, comprising: receiving an RF pilot signal on an operational frequency used in the second environment; downconverting the RF pilot signal to an IF pilot signal; filtering the IF pilot signal; first upconverting the entire filtered IF signal to a first reproduced RF pilot signal that is at an operational frequency used in the first environment, and which represents a pilot beacon for hard handoff from the first environment to the second environment; second upconverting the entire filtered IP signal to a second reproduced RF pilot signal that is at the operational frequency used in the first environment; and transmitting the first reproduced RF pilot signal and the second reproduced RF pilot signal to a base station, wherein the first environment has an operational frequency that is different from one or more operational frequencies in the second environment.
