Using Your VAIO Computer
Wireless LAN devices using the IEEE 802.11a standard and the ones using the IEEE 802.11b or g standard cannot communicate because the frequencies
are different.
IEEE 802.11b: The standard speed is 11 Mbps, or about 30 to 100 times faster than a standard dial up.
IEEE 802.11a/g: The standard speed is 54 Mbps, or about 5 times faster than a wireless LAN device using the IEEE 802.11b standard.
The 2.4 GHz bandwidth used by wireless LAN compatible devices is also used by other various devices. Although technologies to minimize interference
from other devices that use the same bandwidth are employed on wireless LAN compatible devices, such interference may cause lower communication
speed, narrower communication range, or broken wireless connections.
The communication speed varies depending on the distance between communication devices, existence of obstacles between such devices, the device
configuration, the radio conditions, and the software in use. In addition, communications may be cut off depending on the radio conditions.
The communication range varies depending on the actual distance between communication devices, existence of obstacles between such devices, the
radio conditions, the ambient environment that includes existence of walls and materials of such walls, and the software in use.
Deploying IEEE 802.11b and IEEE 802.11g products on the same wireless network may reduce the communication speed due to radio interference.
Taking this into consideration, the IEEE 802.11g products are designed to reduce the communication 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.
