Abstract
A multi-mode wireless device on a single substrate includes an analog portion and a digital portion integrated on the single substrate. The analog portion includes a cellular radio core; and a short-range wireless transceiver core. The digital portion includes a multi-processor core with a master processor coupled to a router which distributes data from the radio chip to a serial-parallel array of DSP processors, each of which is connected to multiple DSP coprocessors. This arrangement allows for decoding both complex protocols at low data rates (like GPRS), simple protocols at high data rates (like 802.11A) and complex protocols at high data rates (like WCDMA), using the same hardware.
Claims23
An apparatus comprising:
- a cellular radio core configured to perform wireless communication according to a first protocol;
- a short-range wireless transceiver core configured to perform short-range wireless communication according to a second protocol different from the first protocol;
- a router coupled to the cellular radio core and the short-range wireless transceiver core;
- wherein the router is configured to send a set of data packets to both the cellular radio core and the short-range wireless transceiver core in response to a determination regarding signal quality of signals sent by the apparatus;
- and
- wherein the cellular radio core and the short-range wireless transceiver core are configured to wirelessly transmit said set of data packets in parallel in response to receiving data packets from the router that are transmitted responsive to the signal quality determination.
A method comprising:
- a communication device transmitting signals via a cellular radio core using a first protocol and via a short-range wireless transceiver core using a second protocol different from the first protocol;
- the communication device making a determination regarding quality of the transmitted signals;
- in response to the determination:
- a router of the communication device sending a set of data packets to both the cellular radio core and the short-range wireless transceiver core;
- and
- the cellular radio core and the short-range wireless transceiver core wirelessly transmitting, in parallel, said set of data packets sent from the router responsive to the determination.
A system comprising:
- a radio frequency (RF) circuit configured to communicate according to at least two wireless protocols, wherein the at least two wireless protocols include a cellular protocol and a short-range protocol;
- a router coupled to the RF circuit;
- wherein the router is configured to send a set of data packets to the RF circuit in response to a determination regarding signal quality of signals sent using the at least two wireless protocols;
- and
- wherein the RF circuit is configured to wirelessly transmit said set of data packets in parallel using each of the at least two wireless protocols in response to receiving data packets from the router that are sent responsive to the signal quality determination.
