Abstract
Methods, systems, and devices are described for limiting the range of an access point. An access point (AP) may transmit a beacon advertising supported for a set of low bit rates to achieve backwards compatibility for devices that expect support for those rates. If a station (STA) sends a data packet using one of the low bit rates, the AP may refrain from transmitting an acknowledgement (ACK) of the transmission to the STA. The AP may also transmit a disassociation or deauthentication frame. This may cause devices outside of a limited range to disassociate from the AP. In some examples, the AP may indicate that it will not communicate using the set of low bit rates. The AP may transmit beacons or probe responses at higher bit rates.
Claims20
A method of wireless communication, comprising:
- advertising, by an access point (AP), a plurality of supported bit rates, wherein the plurality of supported bit rates comprises a first subset of bit rates and a second subset of bit rates;
- receiving a transmission from a wireless station at a first bit rate;
- and
- adapting communication with the wireless station to limit a range of the AP, wherein the adaptation is based at least in part on a determination that the first bit rate is in the first subset.
An apparatus for wireless communication, comprising:
- means for advertising, by an access point (AP), a plurality of supported bit rates, wherein the plurality of supported bit rates comprises a first subset of bit rates and a second subset of bit rates;
- means for receiving a transmission from a wireless station at a first bit rate;
- and
- means for adapting communication with the wireless station to limit a range of the AP, wherein the adaptation is based at least in part on a determination that the first bit rate is in the first subset.
An apparatus for wireless communication, comprising:
- a processor;
- a bit rate advertiser to advertise a plurality of supported bit rates, wherein the plurality of supported bit rates comprises a first subset of bit rates and a second subset of bit rates;
- a receiver to receive a transmission from a wireless station at a first bit rate;
- and
- a communication adapter to adapt communication with the wireless station to limit a range of an access point (AP), wherein the adaptation is based at least in part on a determination that the first bit rate is in the first subset.
