In some countries or regions, using WLAN products may be restricted by the local regulations (e.g. limited number of
channels).
The IEEE 802.11a standard and the IEEE 802.11n standard are not available on ad-hoc networks.
The 2.4 GHz band, with which wireless LAN devices work, is used by various devices. Although the wireless LAN devices
use the technology to minimize radio interference from other devices that use the same band, such radio interference may
cause slower communication speeds and narrower communication ranges or communication failures.
The communication speed and range may vary depending on the following conditions:
❑ Distance between communication devices
❑ Existence of obstacles between devices
❑ Device configuration
❑ Radio conditions
❑ Ambient environment that includes existence of walls and materials of such walls
❑ Software in use
Communications may be cut off depending on radio conditions.
Actual communication speed may not be as fast as the one displayed on your computer.
Deploying WLAN products compliant with different standards that use the same band on the same wireless network may
reduce the communication speed due to radio interference. Taking this into consideration, WLAN products are designed
to reduce the communication speed to ensure communications with another WLAN product if it is compliant with a
different standard that uses the same band. When the communication speed is not as fast as expected, changing the
wireless channel on the access point may increase the communication speed.
