Abstract
Methods and systems for substantially simultaneously scan of two or more frequencies using one transceiver are discussed herein. For example, a listening device can include a controller configured to control its transceiver to alternate between two or more frequencies from two or more sets of frequencies. The controller is also configured to capture a portion of a preamble of a received signal to determine whether the received signal is intended for the listening device.
Claims22
A method, comprising:
- configuring a transceiver of a device to operate at a first frequency of a first set of frequencies;
- receiving a signal from the transceiver;
- capturing a portion of a preamble from the signal;
- determining, based at least in part on the captured portion of the preamble and before capturing a remainder of the preamble, whether the received signal is intended for the device;
- and
- in response to determining that the received signal is not intended for the device, configuring the transceiver to operate at a second frequency of a second set of frequencies.

(canceled)
A method, comprising:
- periodically switching between a first frequency of a first set of frequencies and a second frequency of a second set of frequencies at which a transceiver of a first device operates;
- capturing a portion of a preamble from a signal received from a second device;
- determining, based at least in part on the captured portion of the preamble and before capturing a remaining portion of the preamble, whether the received signal is intended for the first device;
- and
- in response to determining that the received signal is not intended for the device, continuing the periodical switching between the first frequency and the second frequency.
2 more elements
A system, comprising:
- a transceiver comprising a phase lock loop (PLL);
- and
- a controller communicatively coupled to the transceiver, the controller configured to:
- configure the PLL of the transceiver to operate at a first frequency of a first set of frequencies;
- capture a portion of a preamble from a signal received using the transceiver;
- determine, based at least in part on the captured portion of the preamble and before capturing a remainder of the preamble, whether the received signal is intended for the system;
- and
- in response to determining that the received signal is not intended for the system, configure the PLL to operate at a second frequency of a second set of frequencies.
