Abstract
Apparatus and systems, as well as methods and articles, may operate to detect radio-frequency energy at a frequency associated with at least one wireless networking channel and to transmit a data frame responsive to determining that the radio-frequency energy is not associated with a wireless networking transmission.
Claims16
An apparatus, including:
- a detector to detect radio-frequency (RF) energy at a frequency associated with at least one wireless networking channel;
- a contention window comparator coupled to the detector to compare an actual contention window size to an estimated contention window size to determine whether the RF energy is associated with a wireless networking transmission;
- and
- a transmit enable module coupled to the contention window comparator to enable data frame transmission responsive to determining that the RF energy is not associated with a wireless networking transmission.

A system, including:
- a detector to detect radio-frequency (RF) energy at a frequency associated with at least one wireless networking channel;
- a contention window comparator coupled to the transmit enable module to determine whether the RF energy is associated with a wireless networking transmission;
- a transmit enable module coupled to the detector to enable data frame transmission responsive to determining that the RF energy is not associated with a wireless networking transmission;
- and
- an omnidirectional antenna coupled to the transmit enable module.
2 more elements
A method, including:
- detecting radio-frequency (RF) energy at a frequency associated with at least one wireless networking channel;
- comparing an actual contention window size to an estimated contention window size;
- determining that the RF energy is associated with noise if the actual contention window size is substantially greater than the estimated contention window size;
- and
- foregoing back-off and transmitting a data frame responsive to determining that the RF energy is associated with the noise.
2 more elements
An article including a machine-accessible medium having associated information, wherein the information, when accessed, results in a machine performing:
- detecting radio-frequency (RF) energy at a frequency associated with at least one wireless networking channel;
- comparing an actual contention window size to an estimated contention window size;
- determining that the RF energy is associated with noise if the actual contention window size is substantially greater than the estimated contention window size;
- and
- foregoing back-off and transmitting a data frame responsive to determining that the RF energy is associated with the noise.
