Abstract

Technology is creating fast improvement and is creating several things simpler and quicker. Among such technologies, there's wireless communication that was developed to supply a quicker and easier means of transferring knowledge from one device to different with none use of wires. Wireless technology is extremely economical and is straightforward to be used because the innovative thinking step by step, new methods for remote systems administration has been advanced of that our arranged subject Wi-Fi is that the most acknowledged innovation.
Wi-Fi is an acronym for Wireless-Fidelity which is considered as the wireless way to handle networking. Wi-Fi plays a very important role in the field of wireless communication as it is future
• Wi-Fi allows fast data transfer rates.
• There is ease of installation and hence Wi-Fi is quick and easy to be set up.

Disadvantages of Wi-Fi:

• The 802.11b and 802.11g principles of Wi-Fi utilize the 2.4 GHz range, which is swarmed with different gadgets, for example, Bluetooth, microwave broilers, cordless telephones, or feature sender gadgets, among numerous others.
• Power utilization is genuinely high contrasted with different principles, making battery life and warmth a worry.
• It is not generally arranged legitimately by clients.
• Wi-Fi has restricted extent and consequently it is one of the inconveniences

Wi-Fi Security • WEP (Wired Equivalent Privacy): The first encryption system indicated by the IEEE802.11 standard. As its name suggests, this standard was expected to make remote systems as secure as wired systems.
• The basic key lengths are at present 128-and 256-bit.
• WPA (Wi-Fi Protected Access): another standard that gives enhanced encryption security over WEP
• WPA2: It is an enhanced variant of WPA that uses Advanced Encryption Standard (AES) innovation.
• Service Set Identifier (SSID): Without client's SSID, individuals won't have the capacity to join client's Wi-Fi
