Wi-Fi
Wi-Fi
is short for "Wireless
Fidelity".
It's a low-powered connection to exchange data over
a short distance. Wi-Fi can be transmitted from a single unit, or
offered in a network with a large number of interconnected base
stations. These channels are also known as "unlicensed
spectrum".
Wi-Fi
Frequency Bands and Channels:
- 2.4 GHz
- 2,400 MHz to 2,500 MHz
- 12 Channels US, 13 or 14 Channels in other parts
of the world
- 5 GHz
- 5,000 MHz to 5,900 MHz
- 50 Channels
- 6 GHz
- 5,900 MHz to 7,200 MHz
- 100-200 Channels
Wi-Fi
Technologies:
- 802.11
The original engineering standard for Wi-Fi
- 802.11b/g/n/ax
Normal speeds at 2.4GHz
- 802.11a/h/j/ac/ax
Higher speeds at 2.4GHz or 5GHz
- 6e
The
newest generation of Wi-Fi (not to be confused with 6G
Wireless) with
connection speeds that can accomodate 5G Wireless speeds. Uses
the 6 GHz band (5.925 to 7.125 GHz)
- Wi-Fi
7, 802.11be
The
next generation of Wi-Fi using multiple portions of the above bands,
yielding more than double the speeds of Wi-Fi 6. Final standards have been issues and a re under review.
Bluetooth:
Bluetooth
uses the same channels as Wi-Fi Low:
- 2.4 GHz
2,400 MHz to 2,500 MHz
NFC (Near Field Communications):
- 13.56 MHz
Yes,
that's next to the 20-Meter shortwave ham band!
