Using Your VAIO Computer
The IEEE 802.11b/g standard is a wireless LAN standard, using the 2.4 GHz bandwidth. The IEEE 802.11g standard provides high-speed
communications, faster than the IEEE 802.11b standard.
The IEEE 802.11a standard is a wireless LAN standard, using the 5 GHz bandwidth, and provides high-speed communications of up to 54 Mbps.
The IEEE 802.11n draft standard is a wireless LAN standard, using the 2.4 or 5 GHz bandwidth, and provides high-speed communications of up to 144
Mbps
*
on the 2.4 GHz bandwidth or up to 300 Mbps
*
on the 5 GHz bandwidth.
*Actual communication speed varies depending on your access point settings and so on.
Your computer may employ the Intel

compliant with the IEEE 802.11a/b/g standard and the IEEE 802.11n draft
standard.
*Employed only on models that support the IEEE 802.11n draft standard.
Wireless LAN devices using the 2.4 GHz bandwidth and the ones using the 5 GHz bandwidth cannot communicate with each other because the
frequencies are different.
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.
