Wireless Ethernet Speed And Frequency - Gateway M275 Notebook User Manual

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 Speed
IEEE 802.11a 54 Mbps
IEEE 802.11b 11 Mbps
IEEE 802.11g 54 Mbps
Important
The two most common types of wireless Ethernet networks are access point
and peer-to-peer.
Frequency Advantages
5 GHz Less possible
interference than
IEEE 802.11b and
IEEE 802.11g
2.4 GHz Large number of
access points already
exist in airports,
college campuses, and
businesses
Compatible with
IEEE 802.11g
networks
Longer range (100 to
150 feet) than
IEEE 802.11a
2.4 GHz Compatible with
IEEE 802.11b
networks
Longer range (100 to
150 feet) than
IEEE 802.11a
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.

Disadvantages
Shorter range (25 to
75 feet) than
IEEE 802.11b and
IEEE 802.11g
