15. What is GI?

GI stands for Guard Interval. It’s a measure to protect wireless devices from cross-

interference. If there are two wireless devices using the same or near channel, and

they are close enough, radio interference will occur and reduce the radio resource

usability.

16. What is STBC?

STBC stands for Space-Time Block Coding, which is a technique used to transfer

multiple copies of data by multiple antenna, to improve data transfer performance. By

using multiple antennas, not only data transfer rate is improved, but also the wireless

stability.
