First Claim
Patent Images
1. A method of receiving at least one data packet, the method comprising:
- (A) providing a signal for causing a radio to draw power, for a first amount of time, at a first level, below a level which is used to receive at least one data packet, the first level being greater or equal to zero;
(B) at the end of the period, causing the radio to draw power at a second level, higher than the first level;
(C) causing the radio to attempt to receive a set of data following the end of the period;
(D) determining whether the set of data corresponds to a first packet type; and
(E) responsive to the set of data corresponding to the first packet type, identifying an amount of time, responsive to the set of data, and providing a signal for causing the radio to draw power, during the amount of time, at a level below that which is used to receive at least one data packet; and
(F) after the amount of time passes, causing the radio to receive the at least one data packet.

7. A computer program product comprising a computer useable medium having computer readable program code embodied therein for receiving at least one data packet, the computer program product comprising computer readable program code devices configured to cause a computer system to:
-
(A) provide a signal for causing a radio to draw power, for a first amount of time, at a first level, below a level which is used to receive at least one data packet, the first level being greater or equal to zero; (B) at the end of the period, cause the radio to draw power at a second level, higher than the first level; (C) cause the radio to attempt to receive a set of data following the end of the period; (D) determine whether the set of data corresponds to a first packet type; and (E) responsive to the set of data corresponding to the first packet type, identify an amount of time, responsive to the set of data, and providing a signal for causing the radio to draw power, during the amount of time, at a level below that which is used to receive at least one data packet; and (F) after the amount of time passes, cause the radio to receive the at least one data packet. - View Dependent Claims (8, 9, 10, 11, 12)
