Abstract
High speed data transfer from a base station to a mobile terminal is provided using an additional wide band communication channel that supplements the communications provided by the reverse (mobile to base station) and forward (base station to mobile) links used in cellular or PCS communications systems. In one embodiment, the standard forward and reverse links are used as control channels for data transfers over the additional or adjunct forward wide band channel. In another embodiment, the communications carried out over the narrow band forward link channel are sent over the adjunct wide band forward channel thereby eliminating the need for a narrow band forward link channel.
