Versatile solution for public hot spots, wireless meshed networks, industrial applications and office communication.Throughout the recent years, IEEE 802.11 Wireless Local Area Networks (WLAN) have become a popular and widely adopted means for mobile data transmission in various applications. Initially deployed as a picocell wireless extension of Ethernet in offices, hot spot and industrial WLAN networks have grown from local applications to city-wide municipal networks delivering state of the art service to private and public users.
Wireless networks for data transmission – so-called Wireless Local Area Networks – have been under discussion for years, but only since the publication of the 802.11b standard enabling raw transmission rates of 11 Mbps has this vision become a reality. The evolution of new technologies from 802.11a to 802.11g have increased data throughput to 54 Mbps, enabling real time video streaming and rich content applications. With 802.11n making use of MIMO (Multiple Input Multiple Output) technology, capacity will be increased even more up to several 100 Mbps. Wireless local area networks operate in non-licensed frequency bands from 2.4 GHz to 2.4835 and sub-bands from 5.15 to 5.875 GHz. Frequency allocation differs slightly in different countries; detailed information is available from the national regulation authorities/ OFCOMs.
