stbc

interface-config-radio-instance

Configures the radio‘s STBC (Space Time Block Coding) 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 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).

Note

STBC requires the radio has at least two antennas with the capability to transmit two streams. If the antenna mode is configured to 1x1 (or falls back to 1x1 for some reason), STBC support is automatically disabled.

Supported in the following platforms:

Access Points — AP3000/X, AP5010, AP310i/e, AP410i/e, AP460i/e, AP505i, AP510i/e, AP560i/h, AP7612, AP7632, AP7662, AP8533

Syntax

stbc [auto|none|tx-only]

Parameters

stbc [auto|none|tx-only]


stbc	Configures the radio‘s STBC mode
auto	Autoselects STBC settings based on the platform type and other radio interface settings. This is the default setting.
none	Disables STBC support
tx-only	Configures the AP radio to format and broadcast the special stream (enables STBC support for transmit only)
