Wireless Ethernet speed and frequency

Wireless Ethernet is available at two different speeds and at two different
frequencies. The following table compares the various wireless Ethernet
network types.
Network Type
IEEE 802.11a
IEEE 802.11b
IEEE 802.11g
Important
The two most common ways to set up a wireless Ethernet network are access
point and peer-to-peer.
10
Speed Frequency
54 Mbps 5 GHz
11 Mbps 2.4 GHz
54 Mbps 2.4 GHz
The speed of a wireless network is related to signal
strength. Signal strength is affected by the distance
between your wireless network devices, by radio
interference, and by interference from natural obstructions
such as walls, floors, and doors.
