802.11a, 802.11b,
and 802.11n are different Wi-Fi standards that vary in their frequency, maximum
speed, and capabilities. 802.11a operates at 5 GHz with a theoretical
maximum speed of 54 Mbps. 802.11b operates at 2.4 GHz with a theoretical
maximum speed of 11 Mbps. 802.11n operates on both 2.4 GHz and 5 GHz,
offering backward compatibility and a theoretical maximum speed of 600 Mbps.
Here‘s a more
detailed breakdown:
802.11a:
·
Frequency: 5 GHz.
·
Maximum Speed: 54 Mbps.
·
Backward Compatibility: Not backward
compatible with 802.11b.
·
Key Feature: Operates on a less congested 5
GHz frequency, offering higher speeds and less interference compared to
802.11b.
802.11b:
· Frequency: 2.4 GHz.
· Maximum Speed: 11 Mbps.
· Backward
Compatibility: Not backward compatible with 802.11a.
·
Key Feature: Operates on the 2.4 GHz band,
which is prone to interference from other devices like microwaves and
Bluetooth.
802.11n:
·
Frequency: 2.4 GHz and 5 GHz.
·
Maximum Speed: 600 Mbps (theoretical).
·
Backward Compatibility: Backward
compatible with 802.11a, b, and g.
·
Key Feature: Supports both 2.4 GHz and 5 GHz
bands, offers higher speeds and backward compatibility, and uses technology
like MIMO to improve range and throughput.
