INTRODUCTION
In recent years, the use of portable electronic devices has grown exponentially. At the same time, the use of computer networks has expanded dramatically. It was against this backdrop that the Institute of Electrical and Electronics Engineers IEEE 802.11 standard for WLAN (Wireless Local Area Network) emerged. The 802.11 standard was designed to offer stations services comparable to those available on wired LANs (Local Area Networks). The term station is used here to refer to any electronic device that can include an 802.11 interface: conventional and laptop computers, PDAs (Personal Digital Assistants), etc.
The aim of the standard is to provide wireless connectivity to fixed stations or stations moving at low speeds (pedestrians, industrial vehicles) both indoors (airport halls, hospitals) and outdoors (campuses, parking lots).
The advantages of this type of technology are flexibility, ease of use and fast, easy deployment (no cables).
