smart-antenna valid-per-scope

Function

The smart-antenna valid-per-scope command sets the upper and lower valid packet error rate (PER) thresholds in the smart antenna algorithm.

The undo smart-antenna valid-per-scope command restores the default upper and lower valid PER thresholds in the smart antenna algorithm.

The default upper and lower valid PER thresholds are 80% and 20%, respectively.

Format

smart-antenna valid-per-scope { high-per-threshold high-per-threshold | low-per-threshold low-per-threshold }

undo smart-antenna valid-per-scope { high-per-threshold | low-per-threshold }

Parameters

Parameter	Description	Value
high-per-threshold high-per-threshold	Specifies the upper valid PER threshold.	The value is an integer that ranges from 50 to 90, in percentage. In addition, the value must be a multiple of 10.
low-per-threshold low-per-threshold	Specifies the lower valid PER threshold.	The value is an integer that ranges from 10 to 30, in percentage. In addition, the value must be a multiple of 10.

Usage Guidelines

In the smart antenna algorithm, an AP uses different antenna combinations to send training packets for antenna training. During smart antenna training, the transmit end (AP) sends training packets to a receive end (STA). The receive end measures the PER and RSSI in the received packets, and then sends the PER and RSSI to the transmit end. The transmit end collects information about all antenna combinations and corresponding PERs and RSSIs to determine the optimal antenna combination for the receiver.

The PER is a key basis for the smart antenna algorithm. After proper upper and lower valid PER thresholds are configured, the smart antenna algorithm can select a proper antenna combination to improve the coverage and anti-interference capability of a WLAN in indoor coverage scenarios.

Example

# Set the upper valid PER threshold to 80%.
