h3cDot11RadioCfgPreambleLen
Module: A3COM-HUAWEI-DOT11-CFG-MIB
OID (symbolic): A3COM-HUAWEI-DOT11-CFG-MIB::h3cDot11RadioCfgPreambleLen
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.75.4.4.1.1.12
Node type: OBJECT-TYPE
Type: H3cDot11PreambleType
Access: read-write
Description: Represents whether use long or short preamble for 802.11 MAC frame.
What is h3cDot11RadioCfgPreambleLen?
This enumerated value selects between long and short preamble formats prepended to each 802.11 MAC frame. Short preamble reduces overhead and improves throughput on modern hardware; long preamble improves compatibility with older legacy devices. Modern deployments use short preamble exclusively to maximize data rates.
