What is Short Guard Interval (Short GI)?
Short Guard Interval (Short GI) is a setting in WiFi communication that allows for reduced delay between transmitted data packets. In traditional wireless communication, a Guard Interval (GI) is introduced to safeguard against inter-symbol interference (ISI) by providing a buffer time, allowing for the transmission of data over radio waves. While the typical Guard Interval is 800 nanoseconds, Short GI reduces this interval to just 400 nanoseconds, essentially doubling the potential data throughput.
How Short GI Works in WiFi Networks
To truly appreciate the impact of Short GI on your WiFi experience, it is essential to grasp the core principles of how wireless communication functions.
The Basics of WiFi Communication
WiFi operates primarily on the principles of contrasting frequencies and the modulation of signals. Data is sent in packets, and the speed at which these packets are transmitted can significantly impact overall network performance.
- Data Transmission: When a device (like a smartphone or laptop) sends data over a WiFi network, it does so by breaking the information into smaller packets.
- Guard Interval Functionality: A Guard Interval is essentially a pause between these packets that allows them to be properly decoded by the receiving device without overlap, which can lead to data loss.
- Reducing Latency: By cutting the Guard Interval down in half, Short GI enables a denser packing of packets, allowing the signal to flow more rapidly through the airwaves.
