摘要：An adaptive paging system includes a paging terminal that is operable toreceive paging signals and transmit them up to a satellite (28) and down through adownlink (312) to stick locations (314), (316), (318), (320) and (322). Each of the sticks (314)-(322) is associated with a given locale (324), (326), (328), (330) and (332). The sticks areoperable in a simulcast mode and also in a cellular mode. In the cellular mode, each ofthe sticks (314)-(322) is operable to receive a separate message that is distinct from theother cells. Pagers (36), having a known location at any of the locales (324)-(332) can thenbe selectively addressed and data transferred thereto. To prevent interference betweenadjacent RF locales, adjacent cells are not turned on during transmission to select cells inthe cellular mode. These can be turned on at a different time. Orthogonal coding can beutilized such that adjacent cells can be turned on, thus increasing throughput.
