Understanding Wireless Network Bands

The assignment delves into the configuration of wireless network bands, specifically 2.4GHz and 5GHz. It highlights the impact of selecting different wireless modes (e.g., Mixed 802.11n, 802.11g, and 802.11b) on settings like data rate and transmit power. Additionally, it addresses why Short GI might become disabled with certain mode selections and provides references for further learning.
