Usage Guidelines

During data transmission, the receive and transmit ends do not receive and send data at all times. There is an interval between the first and second data receiving or transmission or among multiple transmissions. The interval is called Guard Interval (GI) and can improve the transmission effect.

The GI mode consists of the short interval and common interval. The common interval is 800 ns whereas the short interval is 400 ns. The short interval is applicable to 802.11n and 802.11ac specifications, which can raise the transmission rate of 802.11n and 802.11ac packets.

Example

# Set the GI mode to short.

<Huawei> system-view
[Huawei] wlan 
[Huawei-wlan-view] radio-2g-profile name default
