Using the Wireless LAN
The IEEE 802.11b/g standard is a wirele ss LAN standard, using the 2.4 GHz band. The IEEE 802.11g standard provides highe r-speed communications
than the IEEE 802.11b standard.
The IEEE 802.11a standard is a wireless LAN standard, usin g the 5 GHz band.
The IEEE 802.11n draft standard is a wireless LAN standard, using the 2.4 GHz or 5 GHz band.
Wireless LAN devices using the 2.4 GHz band cannot communicate with devices using the 5 GHz band because the frequencies are different.
The 2.4 GHz band used by wireless LAN compatible d evices is also used by other various devices. A lthough technologies to minimize inter ference from
other devices that use the same band are employed on wireless LAN compatible devices, such inter ference may cause lower communication speed,
narrower communication range, or broken wireless connections.
The communication speed varies depending on the distance betw een communication devices, existence of obstacles between such devices, the device
configuration, the radio conditions, and the software in use. In add ition, communications may be cut off depending on the radio conditions.
The communication range varies depending on the actual dista nce between communication devices, existence of obstacles betw een such devices, the
radio conditions, the ambient environment that includes existence of wal ls and materials of such walls, and the software in use.
Actual communication speed may not be as fast as the one displayed on your computer.
Deploying IEEE 802.11b and IEEE 802.11g products on th e same wireless network may reduce the communication speed due to ra dio interference.
Taking this into consideration, the IEEE 802.11g products are designed to reduce the communicati on speed to ensure communications with
IEEE 802.11b products. When the communication speed is not as fast as expected, changing the wireless channel on the access point may increase
the communication speed.
