ELECTRONIC APPARATUS HAVING A FIRST RADIO, AND A SECOND LOW POWER RADIO FOR WAKING THE FIRST RADIO

摘要

An electronic apparatus used with a separate electronic device, and including: a first radio that wirelessly communicates with the electronic device at a first transmission power in a first power range according to a first wireless protocol; and a second radio that wirelessly communicates the electronic device at a second transmission power in a second power range, that is lower than the first power range, according to a second wireless protocol. The electronic apparatus includes a control circuit that determines whether the first radio is in a power-down state or a power-up state, determines whether a predetermined condition exists, powers-down the first radio when the predetermined condition exists, determines whether a predetermined message is received by the second radio, and powers-up the first radio when it is determined that the predetermined message is received while the first radio is in the power-down state.

主权项

1. An electronic apparatus for use with a separate electronic device, said electronic apparatus comprising:
a first wireless communication circuit that wirelessly communicates information with the electronic device at a first transmission power in a first power range according to a first wireless protocol; a second wireless communication circuit that wirelessly communicates information with the electronic device at a second transmission power in a second power range, that is lower than the first power range, according to a second wireless protocol; a control circuit that controls the first and second wireless communication circuits, determines whether the first wireless communication circuit is in a power-down state or a powered-up state, determines whether a predetermined condition exists, powers-down the first wireless communication circuit when the predetermined condition exists, determines whether a predetermined message is received by said second wireless communication circuit, and powers-up the first communication circuit when it is determined that the predetermined message is received via said second communication circuit while said first wireless communication circuit is in the power-down state.
