1. A method of establishing wireless communication between a first device and a second device, the method comprising:
- determining whether the first device is turned “
on”
to transmit for a first time, is attempting a retry to establish communication with the second device, or has already established communication with the second device;
transmitting at a power level depending on whether the transmitting is a first time transmission, a retry transmission, or a transmission after a reply has been received from the second device; and
upon determining the transmitting is a retry transmission, transmitting via a second antenna different from a first antenna used in a previous transmission.

Abstract
Reducing power consumption and interference in wireless communication is provided. For example, in one embodiment, a method is provided that listens for radio frequency (“RF”) activity on a receiver utilizing a first receiver antenna. When no RF activity is detected the receiver is switched “on” and a command is transmitted. If a reply to the transmission is not received the receiver is turned “off.” After an expiration of time, the receiver is again switched “on” and another command is transmitted on a second antenna coupled to the receiver. Thereafter, if a reply is not received the receiver is again turned “off.” Embodiments of the invention also include other methods, computer-readable mediums, apparatuses, and systems that contain features similar to the features in the above described method.

6. A method of establishing wireless communication between a first device and a second device, the method comprising:
-
determining whether the first device is turned “
on”
to transmit for a first time, is attempting a retry to establish communication with the second device, or has already established communication with the second device;performing a listen before talk (LBT) operation to detect in band activity before transmitting; and transmitting at a power level depending on whether the transmitting is a first time transmission, a retry transmission, or a transmission after a reply has been received from the second device, wherein the power level is incrementally increased if a signal strength indication flag in the reply received by the first device indicates the power level should be increased. - View Dependent Claims (7)

-
determining whether the first device is turned “

10. A method comprising:
-
determining whether a device is turned “
on”
to wirelessly transmit a command for a first time;performing a listen before talk (LBT) operation to detect in band activity before transmitting; and transmitting at a power level indicated by a received signal strength indication flag if the device has previously transmitted a command and has received a reply that included the power level indication flag, wherein the power level is incrementally increased if the signal strength indication flag indicates the power level should be increased. - View Dependent Claims (11)
