Description

The world of wireless networks is rapidly being enriched with new norms and standards. These networks allow company equipment such as voice, data and images to be connected together. They are also the basis of operators’ “hot spots”. IEEE 802.11 networks (Wi-Fi and all variations), Bluetooth, UWB, Zigbee, IEEE 802.16, WiMAX, WRAN, etc., will be studied in detail in this seminar as well as the applications that can be associated with them.
