You are reconfiguring an AP to use the short guard interval. How long will the new guard interval duration be after the change?
You are reconfiguring an AP to use the short guard interval. How long will the new guard interval duration be after the change?
When reconfiguring an Access Point (AP) to use the short guard interval, the new guard interval duration will be 400 nanoseconds (ns). This is standard for many modern wireless networks, including 802.11n, where the short guard interval helps to increase data throughput by reducing the delay between symbol transmissions.
A is correct
The 802.11n draft specifies two guard intervals: 400ns (short) and 800ns (long). https://www.cwnp.com/802-11n-guard-intervals-gi/
So for the answer, it can be A or C then? which one to choose?
