In a method for generating pilot beacons for hard handoff over a border from a first environment to a second environment, the two environments using spread spectrum technology, a RF pilot signal may be received at an operational frequency used in at least the second environment. The RF signal may be downconverted to an IF pilot signal, filtered and then upconverted to a first reproduced RF pilot signal. The first reproduced RF pilot signal may be at a operational frequency used in a first environment, and may represent a pilot beacon for hard handoff between the first and second environments. The method and arrangement may be configured to receive a pilot beacon from one environment and to generate N pilot beacons, in that one environment, for up to N different operational frequencies used in another environment from which a mobile user is transiting, for hard handoff between the environments.
