Abstract
Passive listening in wireless communication. An activity sensor device senses a packet. A medium access control (MAC) address parser receives the packet, processes a header of the packet, and activates a MAC device in response to recognizing a MAC address within the header, such that the MAC device is not activated if the MAC address parser does not recognize the MAC address.
Claims20
An apparatus comprising:
- an activity sensor device for sensing a packet;
- and
- a medium access control (MAC) address parser for receiving said packet, for processing a header of said packet, and for activating a MAC device in response to recognizing a MAC address within said header, such that said MAC device is not activated if said MAC address parser does not recognize said MAC address.
An apparatus comprising:
- an activity sensor device for sensing a packet;
- a physical layer device for decoding at least said header of said packet, wherein said physical layer device is activated in response to said activity sensor device sensing said packet;
- a medium access control (MAC) address parser for receiving said packet, for processing said header of said packet, and for activating a MAC device in response to recognizing a MAC address within said header, such that said MAC device is not activated if said MAC address parser does not recognize said MAC address;
- and
- an activity sensor control module for controlling activation and deactivation of said activity sensor device, said physical layer device, said MAC device and said MAC address parser.
2 more elements
A method comprising:
- sensing a packet at an activity sensor device;
- responsive to said sensing, decoding at least a header portion of said packet at a physical layer device, said header portion including a destination medium access control (MAC) address;
- determining whether said MAC address of said packet is recognized;
- and
- responsive to recognizing said MAC address, activating a MAC device for performing data processing functions such that said MAC device is not activated if said MAC address is not recognized.
