dot11HRCCAModeSupported
Module: IEEE802dot11-MIB
OID (symbolic): IEEE802dot11-MIB::dot11HRCCAModeSupported
OID (numeric): 1.2.840.10036.4.12.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description:
dot11HRCCAModeSupported is a bit-significant value, representing all of the CCA modes supported by the PHY. Valid values are: energy detect only (ED_ONLY) = 01, carrier sense only (CS_ONLY) = 02, carrier sense and energy detect (ED_and_CS)= 04 carrier sense with timer (CS_and_Timer)= 08 high rate carrier sense and energy detect (HRCS_and_ED)= 16 or the logical sum of any of these values. In the high rate extension PHY, this attribute shall be used in preference to the dot11CCAModeSupported attribute.
What is dot11HRCCAModeSupported?
This OID indicates which methods a wireless radio supports for detecting if a channel is busy before transmitting. The device can use energy detection, listening for carrier signals, or a combination of methods. A network operator would check this to understand which channel access techniques the wireless access point can use to avoid collisions with other devices.
