Enabling and Disabling Gratuitous Probe Response
Enabling and Disabling Gratuitous Probe Response
Gratuitous Probe Response (GPR) aids in conserving battery power in dual mode phones that support
cellular and WLAN modes of operation. GPR is available on 5-Ghz radios and is disabled by default.
You can configure two GPR settings:
•
Period—This setting determines the time between GPR transmissions in Kusec intervals from 10 to
255 (similar to the beacon period)
•
Speed—The speed is the data rate used to transmit the GPR
Selecting a longer period reduces the amount of RF bandwidth consumed by the GPR with the possibility
of shorter battery life. Selecting higher transmission speeds also reduces the amount of bandwidth
consumed but at the expense of a smaller cell size.
To enable GPR and set its parameters, follow these steps, beginning in privileged EXEC mode.

DETAILED STEPS
Step 5
antenna transmit
{
diversity | left | right
}
Sets the transmit antenna to diversity, left, or right.
Note
For best performance with two antennas, leave the
receive antenna setting at the default setting,
diversity
.
For one antenna, attach the antenna on the right and set
the antenna for
right
.
Step 6
end
Returns to privileged EXEC mode.
