The use of wireless communications is being rapidly implemented in the industrial environment with great success provided certain ground rules are applied such as ensuring a robust wireless link, correct integration with the wired communications systems and proper data security.
The most important objective of wireless communications networks must be to achieve similar capacities, bandwidths, responsiveness and availability to that of wire based communications.
This manual commences with an overview of wireless communications and how radio works. A detailed examination is then made of Wireless Personal Area Networks or WPANs (Bluetooth/IEEE 802.15) which are similar to their wired counterparts but based on radio. Wireless Local Area Networks or WLANs (IEEE 802.11) are then reviewed with a practical comparison to the standard wired LANs. Wireless Wide Area Networks are then examined with an emphasis on how they are expanding to provide broadband services.
