Abstract

A spread-spectrum, code-division-multiple-access (CDMA), system with a remote station (RS) communicating with a first base station (BS). The remote station receives the first BS-packet signal, and transmits a first RS-packet signal to the first base station. The first RS-packet signal is spread by a first RS-chip-sequence signal at a second frequency. The first base station receives the first RS-packet signal. The first base station stores and forwards the despread first RS-packet signal to a central office (CO). The remote station monitors control and packet transmission channels of other base stations in geographic proximity to the remote station. Each of the base stations transmit BS-packet signals. The remote station determines, based on signal metrics and available capacity, when to change from the first base station to the second base station. The second base station stores and then forwards the despread second RS-packet signal to the central office. The despread second RS-packet signal includes a source address from the second base station and the source address from the remote station. For return communications from the central office, the central office reads the source address from the second base station, and routes return packet signals, denoted herein as CO-packet through the second base station to the remote station.
