Multi-mode wireless devices having reduced-mode receivers

摘要

Multi-mode wireless devices having single-mode or reduced-mode receivers. In one embodiment, a wireless device is provided with a transmitter and a receiver. The transmitter transmits with any one of multiple selectable modulation techniques, the selected modulation technique being selected to correspond to a modulation technique supported by a target wireless device. The receiver receives signals modulated in accordance any one of a subset of the selectable modulation techniques. The subset might include only one modulation technique. Also disclosed is a wireless communications method in a wireless device having a transmitter configurable to transmit in at least one modulation mode other than that receivable by the wireless device.
