摘要： A portable computing device includes a radio frequency (RF) wired link, a core module, and a plurality of multi-mode RF units. When one or more of the multi-mode RF units are supporting a high-speed data communication, the core module is operable to detect a blocker that is adversely affecting the high-speed data communication. The core module is further operable to determine whether a radiation pattern alternative for the high-speed data communication will reduce the adverse affects on the high-speed data communication. When the radiation pattern alternative for the high-speed data communication will reduce the adverse affects on the high-speed data communication, the core module is further operable to enable the radiation pattern alternative. The one or more multi-mode RF units are operable to adjust at least one of transmission and reception of the high-speed data communication in accordance with the radiation pattern alternative.

摘要： A Voice-Data-RF IC includes a baseband processing module, an RF section, and an interface module. The baseband processing module converts an outbound voice signal into an outbound voice symbol stream, converts an inbound voice symbol stream into an inbound voice signal, converts outbound data into an outbound data symbol stream, and converts an inbound data symbol stream into inbound data. The RF section converts an inbound RF voice signal into the inbound voice symbol stream, converts the outbound voice symbol stream into an outbound RF voice signal, converts an inbound RF data signal into the inbound data symbol stream, and converts the outbound data symbol stream into an outbound RF data signal. The interface module provides coupling between the baseband processing module, the RF section, and with off-chip circuits.
