Wireless OptionsThe WLAN standard is completely codified by the standard-developing committeeof the engineering organization IEEE (Institute of Electrical and ElectronicsEngineers, Standards Organization). Diverse industry groups work withthe IEEE to continuously improve the compatibility and security of WLAN andto inform the general public of the technology (e.g.: WECA = Wireless EthernetCompatibility Alliance, originator of the term Wi-Fi = Wireless Fidelity).4Here is an overview of the different WLAN standards:There are, in the meantime, multiple WLAN standards. Often newer standardsare designed to be backwards compatible. This means that new componentscan facilitate communication to older hardware, but without thefull performance. Below you see a tabular overview of the most commonWLAN standards:IEEE standard 802.11b 802.11a 802.11g aMax. speed 11 Mbit/s 54 Mbit/s 54 Mbit/sFrequency 2.4 GHz 5 GHz 2.4 GHzRange at 11 (54) Mbit/s 30 to 300 metres 10 to 100 metres 30 to 300 metresRange at 1 (6) Mbit/s 100 to 300 metres 50 to 200 metres 100 to 300 metresCompatibility to 802.11g No to 802.11bAdoption of the standards 1999 2001 2003Prevalence High Still low but climbing Still low but climbingTable 5 The most common WLAN standardsa. included in deliveryWith the colibri X5 you can operate both wireless options simultaneouslyand without impairing the protection class of the device (IP 54 / IP 66 frontsided).You will not find this special feature anywhere else! Additionally, youstill have a free USB slot on the rear of the device as well as the PCMCIA slot(on the right of the device).96Documentation
