wifi wireless fidelity 2019

Wi-Fi (wireless fidelity) is one of the most widely used non-cellular wireless technologies. Wi-Fi is the trade name for products and systems that use the IEEE’s 802.11 standards for wireless local area networks (WLAN). The 802.11g standard uses the 2.4 GHz band and OFDM to boost speeds to 54 Mb/s.

One of the most prominent cellular technologies, Long Term Evolution (LTE), is currently Operating on some 800MHz, 2GHz, and 3.5 GHz licensed bands. Wi – Fi is currently operating n 2.5 GHz and 5GHz unlicensed bands. The declaration stating that 5GHz bands arehe connection establishment and client handover mechanism for Wi – Fi Protected Access WPA/WPA2) Pre-Shared Key (PSK) networks described by the IEEE 802.11 standard are Vulnerable to various attacks. The existing security protocols WPA/WPA2 use symmetric key
