The present invention is a extended range concentric cell base station and a method for extending a cell size or access range without incurring ASIC correlator re-design. This is accomplished with a concentric cell base station design that incorporates multiple timing protocols. The concentric base station has associated a micro cell and a macro cell, wherein the micro and macro cells use a different timing protocol that will cause signals transmitted by mobiles within their respective cells to be received within the confines of search windows associated with the timing protocols.

[We claim:] [1.]transmitting a base station signal using a first frequency at a first frame boundary;transmitting a base station signal using a second frequency at a time r relative to a second frame boundary;receiving a mobile-telephone signal transmitted on the first frequency within a first search window beginning at a third frame boundary and ending at a time p.sub.1 after the third frame boundary, wherein p.sub.1 represents a time interval corresponding to a bit limitation for a first correlator; andreceiving a mobile-telephone signal transmitted on the second frequency within a second search window beginning at a time q after a time r relative to a fourth frame boundary and ending at a time q+p.sub.2 after the time r relative to the fourth frame boundary, wherein q is a timing advance value and p.sub.2 represents a time interval corresponding to a bit limitation for a second correlator.
