Claims

1. A mobile communication device operable as a mobile wireless access point, comprising:
a processor and memory, the memory storing software that, upon execution by said processor, causes the processor to:
read from said memory a wireless local area network (WLAN) identifier that is known to be used by a WLAN;
read from said memory an indication of a channel on which a wireless access point of said WLAN is known to operate, the channel being a first channel and having an associated center frequency within a frequency band;
read from said memory an indication of an other channel that is known to be used by an other wireless access point of said WLAN, the other channel having an associated center frequency within said frequency band that is different from the center frequency of the first channel;
select one of the channel and the other channel, the selecting resulting in a selected channel;
monitor only the selected channel for a transmission of the WLAN identifier, the transmission, if detected, indicating that the mobile communication device is within the WLAN; and
upon detection of the transmission of the WLAN identifier, prevent the mobile wireless access point at the mobile communication device from using the WLAN identifier.
2. The mobile communication device of claim 1 wherein said preventing the mobile wireless access point at the mobile communication device from using the WLAN identifier comprises disabling the mobile wireless access point.
3. The mobile communication device of claim 1 wherein said preventing the mobile wireless access point at the mobile communication device from using the WLAN identifier comprises requiring the mobile wireless access point to use a different WLAN identifier.
4. The mobile communication device of claim 1 wherein said monitoring of only the selected channel for the transmission of the WLAN identifier of the WLAN is conditional upon a determination that the mobile communication device is in motion.
5. The mobile communication device of claim 1 wherein said monitoring of only the selected channel for the transmission of the WLAN identifier of the WLAN is conditional upon a determination that the mobile communication device is presently situated in a geographical location that is known to be proximate to the WLAN.
6. The mobile communication device of claim 1 further comprising, prior to the monitoring, configuring the mobile wireless access point functionality to operate using the selected channel.
7. A method of promoting network security in a wireless local area network (WLAN) comprising multiple WLAN cells, each WLAN cell comprising a wireless access point, the method comprising:
at a mobile communication device having a mobile wireless access point functionality:
receiving an indication of a WLAN identifier to be used for identifying the WLAN;
receiving an indication of a plurality of channels to be selectively used by individual ones of the wireless access points of the WLAN, each of the channels having a distinct center frequency;
selecting a channel of the plurality, the selecting resulting in a selected channel;
monitoring only the selected channel, and not any unselected channel of the plurality of channels, for a transmission of the WLAN identifier, the transmission, if detected, indicating that the mobile communication device is within one of the WLAN cells; and
upon detecting the transmission of the WLAN identifier, preventing the mobile wireless access point functionality at the mobile communication device from using the WLAN identifier.
8. The method of claim 7 wherein said preventing the mobile wireless access point functionality at the mobile communication device from using the WLAN identifier comprises deactivating the mobile wireless access point functionality at the mobile communication device.
9. The method of claim 7 wherein said preventing the mobile wireless access point functionality at the mobile communication device from using the WLAN identifier comprises requiring the mobile wireless access point functionality to use a different WLAN identifier.
10. The method of claim 7 further comprising, prior to the monitoring, configuring the mobile wireless access point functionality to operate using the selected channel and wherein said monitoring is only of the selected channel and not of any unselected channel.
11. The method of claim 7 wherein the selecting is based, at least in part, on the identity of a channel on which the mobile wireless access point is already configured to operate.
12. A method of promoting network security in a wireless local area network (WLAN) comprising a wireless access point, the method comprising:
at a mobile communication device having a mobile wireless access point functionality:
receiving an indication of a WLAN identifier known to be used by the wireless access point for identifying the WLAN;
receiving an indication of a channel known to be used by the wireless access point of the WLAN, the channel being a first channel and having an associated center frequency within a frequency band;
further receiving an indication of an other channel known to be used by an other wireless access point of the WLAN, the other channel having an associated center frequency within said frequency band that is different from the center frequency of the first channel;
selecting one of the first channel and the other channel, the selecting resulting in a selected channel;
monitoring only the selected channel for a transmission of the WLAN identifier, the transmission, if detected, indicating that the mobile communication device is within the WLAN; and
upon detecting the transmission of the WLAN identifier, preventing the mobile wireless access point functionality from using the WLAN identifier at the mobile communication device.
13. The method of claim 12 wherein said preventing the mobile wireless access point functionality at the mobile communication device from using the WLAN identifier comprises deactivating the mobile wireless access point functionality at the mobile communication device.
14. The method of claim 12 wherein said preventing the mobile wireless access point functionality at the mobile communication device from using the WLAN identifier comprises requiring the mobile wireless access point functionality to use a different WLAN identifier.
15. A non-transitory machine-readable medium storing software that, upon execution by a processor of a mobile communication device that is operable as a mobile wireless access point, causes the mobile communication device to:
read a wireless local area network (WLAN) identifier that is known to be used by a WLAN;
read an indication of a channel on which a wireless access point of said WLAN is known to operate, the channel being a first channel and having an associated center frequency within a frequency band;
read from said memory an indication of an other channel known to be used by an other wireless access point of the WLAN, the other channel having an associated center frequency within said frequency band that is different from the center frequency of the first channel;
select one of the first channel and the other channel, the selecting resulting in a selected channel;
monitor only the selected channel for a transmission of the WLAN identifier, the transmission, if detected, indicating that the mobile communication device is within the WLAN; and
upon detection of the transmission of the WLAN identifier, prevent the mobile wireless access point at the mobile communication device from using the WLAN identifier.
16. The non-transitory machine-readable medium of claim 15 wherein said preventing the mobile wireless access point at the mobile communication device from using the WLAN identifier comprises disabling the mobile wireless access point or requiring the mobile wireless access point to use a different WLAN identifier.
17. The non-transitory machine-readable medium of claim 15 wherein said monitoring of only the selected channel for the transmission of the WLAN identifier of the WLAN is conditional upon a determination that the mobile communication device is in motion.
18. The non-transitory machine-readable medium of claim 15 wherein said monitoring of only the selected channel for the transmission of the WLAN identifier of the WLAN is conditional upon a determination that the mobile communication device is presently situated in a geographical location that is known to be proximate to the WLAN.
