Using a wireless Ethernet network 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 Speed 54 Mbps 11 Mbps 54 Mbps Frequency 5 GHz 2.4 GHz 2.4 GHz Advantages Less possible interference than IEEE 802.11b and IEEE 802.11g ■ 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 ■ Compatible with IEEE 802.11b networks ■ Longer range (100 to 150 feet) than IEEE 802.11a Disadvantages ■ Shorter range (25 to 75 feet) than IEEE 802.11b and IEEE 802.11g ■ Not compatible with IEEE 802.11b or IEEE 802.11g networks ■ Possible interference from cordless phones and microwaves ■ Not compatible with IEEE 802.11a networks ■ Possible interference from cordless phones and microwaves ■ Not compatible with IEEE 802.11a networks Important 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. The two most common types of wireless Ethernet networks are access point and peer-to-peer. www.gateway.com 205
