Abstract
In various embodiments, a network device may transmit its desired proximity range in the form of a proximity information element (IE) in a beacon or a request frame. The IE may contain threshold values for a Receive Channel Power Indicator (RCPI) and a Receive Signal to Noise Indicator (RSNI). Only devices that receive the beacon or request frame with measured signal values at least as great as the RCPI and RSNI values will respond. Devices that receive the beacon or request frame with measured values less than the RCPI and/or the RSNI should not respond, thus reducing the volume of communications on the network at that time.
Claims22
An apparatus, comprising
- a first wireless communications device, the first device to:
- receive a transmission from a second wireless communications device, the transmission comprising a first value for a receive channel power indicator (RCPI) and a second value for a receive signal to noise indicator (RSNI);
- measure an actual RCPI value for a signal of the received transmission;
- measure an actual RSNI value for the signal of the received transmission;
- reply to the received transmission if the actual RCPI value is greater than the first value and the actual RSNI value is greater than the second value;
- and
- not reply to the received transmission if the actual RCPI value is less than the first value or the actual RSNI value is less than the second value.
A method, comprising:
- receiving a wireless transmission from a wireless communications device, contents of the transmission comprising a first value for a receive channel power indicator (RCPI) and a second value for a receive signal to noise indicator (RSNI);
- measuring an actual RCPI value for a signal of the received transmission;
- measuring an actual RSNI value for the signal of the received transmission;
- replying to the received transmission if the actual RCPI value is greater than the first value and the actual RSNI value is greater than the second value;
- and
- not replying to the received transmission if the actual RCPI value is less than the first value or the actual RSNI value is less than the second value.
An article comprising a tangible computer-readable medium that contains instructions, which when executed by one or more processors result in performing operations comprising:
- receiving a wireless transmission from a wireless communications device, contents of the transmission comprising a first value for a receive channel power indicator (RCPI) and a second value for a receive signal to noise indicator (RSNI);
- measuring an actual RCPI value for a signal of the received transmission;
- measuring an actual RSNI value for a signal of the received transmission;
- replying to the received transmission if the actual RCPI value is greater than the first value and the actual RSNI value is greater than the second value;
- and
- not replying to the received transmission if the actual RCPI value is less than the first value or the actual RSNI value is less than the second value.
