7.1.21.4.31stbc
 interface radio instance
Configures the radio’s Space Time Block Coding (STBC) mode. STBC is a pre-transmission encoding scheme providing an
improved SNR ratio (even at a single RF receiver). STBC transmits multiple data stream copies across multiple antennas.
The receiver combines the multiple copies into one to retrieve data from the signal. These transmitted data versions
provide redundancy to increase the odds of receiving data streams with a good data decode (especially in noisy
environments).
Supported in the following platforms:
• Access Points — AP621, AP622, AP6511, AP6521, AP81XX
Syntax
stbc [none|tx-only]
Parameters

NOTE: STBC requires the radio to have at least two antennas with capability of
transmitting two streams.If the antenna mode is configured to 1x1 (or falls back to 1x1
for some reason), STBC support will be automatically disabled.
none Disables STBC support (default setting)
tx-only Configures the AP radio to format and broadcast the special stream (enables STBC support
for transmit only)
no Disables STBC support
