Frequency Attributes Flashcards
Attributes
2.4 GHz
Have to be careful when configuring channels to avoid overlap
Preferred Channels to Use: 1, 6, and 11
Attributes
5 GHz
Shorter range, Less interference, More trouble penetrating obstacles (walls)
Attributes
6 GHz
6 GHz frequency band is relatively new for Wi-Fi usage. It’s part of the Wi-Fi 6E standard, which extends the capabilities of Wi-Fi 6 (802.11ax) into the 6 GHz frequency spectrum. This spectrum offers significantly more available bandwidth compared to the 2.4 GHz and 5 GHz bands traditionally used for Wi-Fi. The introduction of the 6 GHz band aims to alleviate congestion and provide more channels for Wi-Fi devices, thereby improving overall network performance.
In the United States, the Federal Communications Commission (FCC) has allocated the 6 GHz band for unlicensed Wi-Fi use. This allocation has opened up a large amount of spectrum for Wi-Fi devices, paving the way for increased wireless capacity and higher data rates.
As for the number of channels available in the 6 GHz band, it can vary depending on the regulatory domain and specific implementations. However, the FCC’s allocation provides for up to seven 160 MHz channels or fourteen 80 MHz channels in the 6 GHz band for Wi-Fi operation. These channels are designated specifically for Wi-Fi use and are distinct from those used by other services or technologies.
The availability of additional channels in the 6 GHz band offers several benefits for Wi-Fi networks, including reduced interference, increased network capacity, and improved performance for bandwidth-intensive applications. However, as with any wireless technology, proper channel planning and management are essential to ensure optimal performance and minimize interference, especially in dense deployment environments.
