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.

Claims

1. A method comprising:

listening for radio frequency (“

RF”

) activity on a receiver utilizing a first receiver antenna;

transmitting a command when no RF activity is detected;

switching said receiver “

on”

after said transmission;

turning said receiver “

off”

when said receiver does not receive a reply;

switching said receiver “

on”

to receive said reply;

transmitting another command on a second device antenna when no reply is received; and

switching said receiver “

off”

when no reply is received utilizing said second antenna.

2. The method of claim 1, wherein said receiver comprises a security device and said command comprises a “

Request_for_Update.”

3. A method comprising:

determining whether a device is turned “

on”

for a first time; and

transmitting at a power level indicated by a received power level indication flag.

4. The method of claim 3, wherein said power level indication flag indicates one of reducing said power level by about 5 decibels and increasing said power level by about 5 decibels.
