Wireless LAN (WLAN)

Wireless LAN (IEEE 802.11) is well suited for monitoring, configuring and data acquiring, but can also be used for time critical control. Further, the built-in roaming functionality is useful in factory automation applications with moving devices. Implementing Wireless LAN in these types of applications often requires customized solutions such as tailored or proprietary roaming software as well as frequency planning and specific installation means (for example, the use of expensive leakage-cables). With these tailoring of the wireless solution, one achieves stabile latency and low roaming hand-over delays.

Wireless LAN Facts

• Range of 200 meters (up to 400-500 meters in free line-of-sight) in the 2.4 GHz band and some 50 meters in the 5 GHz band (802.11a) (free line of sight up to 150 meters); however, obstacles and interference could lower the range substantially.
• Data throughput of 11 to 54 Mbit/s gross (~5 to 25 Mbit/s net) for IEEE 802.11b/g and 300 Mbit/s gross (~70 Mbit/s net for IEEE 802.11n).
• Security models like WEP, WPA, WPA2, TPIK and PSK EAP.
• IEEE 802.11a operates on the 5 GHz band and provides the possibility for 19 additional non-overlapping channels in addition to the three non-overlapping channels in the 2.4 GHz band.
• High availability in consumer products.
