Abstract: A method and system for producing a plurality of pilot beacon signals with different carrier frequencies is disclosed. One original pilot beacon signal is first obtained, and a splitter is used to make copies of the pilot beacon signal. Each of the copies are fed into a mixer for generating a plurality of intermediate signals with different frequencies. A bandpass filter is subsequently used to select a final one among the intermediate signals. Thus, a set of pilot beacon signals with different frequencies are successfully obtained.

Abstract: 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.

Abstract: A multichannel radiotelephony system provides two way cordless communications with a plurality of multichannel transceivers portable within a coverage area comprised by a plurality of cells, each associated with a base station and antennas, such as to permit channel frequency reuse in cells within the coverage area. For at least part of the coverage area, the locations of the antennas within the cells and the locations of the base stations are independently mapped, the antennas being associated with active antenna systems and the active antenna systems being connected to the base stations utilizing broadband transmission by means of a fixed bi-directional signal distribution network. The network is connected to the base stations and the antenna systems through suitable interfaces incorporating frequency translation so that available frequency bands in the signal distribution network which will normally be shared with other services, may be utilised. Plural base stations may be co-located.
