A method and system for providing a precision hard handoff between two networks is disclosed. The two networks include a first wireless communication system for serving a defined area, such as a campus, at a first frequency and a second wireless communication system adjacent to the first system and operating at a second frequency. A first pilot beacon distributor is positioned at a transition point of the campus for directionally transmitting a first pilot beacon signal into the campus. When a mobile unit operating on the second frequency crosses the transition point into the campus, it receives the first pilot beacon signal and it shifts operation to the first frequency.

1. A method for a precision hard handoff from a covering network having a first frequency to a target network having a second frequency, said covering network and said target network both using CDMA technology, said method comprising the steps of:installing a plurality of pilot beacon distributors having paired directional antennas; transmitting a pilot beacon signal from one of the pilot beacon distributors; and triggering a precision hard handoff of the mobile unit from the covering network to the target network by using the pilot beacon signal, wherein all the above steps are performed in a small border area between the covering network and the target network.
