Wireless Security is the security mechanism implemented in Wi-Fi Wireless network to protect it from un-authorized access performed by attackers. IEEE 802.11i is the security standard amendment for IEEE 802.11 wireless standard. Wired Equivalent Privacy (WEP) was the initial security algorithm used in IEEE 802.11. WEP was vulnerable and exploitable. Wi-Fi Alliance brought in WPA…

Ciphertext
Ciphertext is the encrypted form of the plaintext that is encrypted by an encryption algorithm. When a data needs to be transmitted but kept confidential, so that nobody can read the data while in transit, encryption process is used. On the sender side, the plaintext is given as input into encryption algorithm which does complex…
Wireless Network
Wireless Network is a Network that uses Wireless for Communication for data and voice transmission. Wireless Network doesn’t use physical cables for data transmission rather it uses radio waves to transmit data. Wireless Personal Area Network, Wireless Local Area Network (WLAN), Cellular Networks, Wireless Metropolitan Area Network (WMAN), Wireless Wide Area Network (WWAN) are various Wireless…
IEEE
Institute of Electrical and Electronics Engineers (IEEE) is a non-profit organization founded in 1963. It is the world largest technical professional organization of STEM (Science, Technology, Engineering, and Mathematics) engineers focusing on technology advancement and innovation. IEEE develops standards through it’s operating unit Institute of Electrical and Electronics Engineers Standards Association (IEEE SA). IEEE covers multiple areas like Computing,…
Radio waves
Radio waves are waves of high wavelength and low frequency in the electromagnetic wave spectrum. The Radio wave spectrum frequency ranges from 3 KHz to 3,000 GHz. Radio Waves are governed by International Telecommunication Union (ITU). The theory of Radio Waves was brough in by Physicist and Mathematician James Clerk Maxwell in 1865. In 1880s, Physicist Heinrich Rudolf Hertz proved…
ITU
ITU (International Telecommunication Union) is a special agency of United Nations that is responsible for governing matters related to Information and Communication Technologies (ICT). It was established in 1865 to support and help governing Telegraphic Networks globally. ITU has member states across the globe. Each country manages the radio spectrum within their country. The management…
Digital Electronics
Digital Electronics is the foundation of Computing Systems and Digital Communications which brought in the concept of Digitalization using electronic components like resistors, capacitor, logic gates, amplifiers to convert analog signals into discrete digital signals. Data was processed, stored and transmitted digitally.
Wireless
Wireless also known as Wireless Communication is the term referred when the communication between systems happens without any physical wires. The communication of data or voice happens in free space using Radio waves. Radio waves are electromagnetic waves with low frequency and high wavelength in the electromagnetic spectrum. Wireless is used in Wi-Fi Network, Satellite…
Electromagetic Waves
Electromagnetic (EM) wave also known as Electromagnetic Radiation is a self-propagating wave energy that travels at the speed of light in the form oscillating electric and magnetic fields perpendicular to each other. Electromagnetic Wave is generated when electric particles are accelerated though matter which generates electromagnetic radiation. Electromagnetic waves can travel through vacuum. Accelerating electric charge…
Energy
Energy is defined as the ability to do work. It is measured in Joule (J) named after PhysicistJames Prescott Joule who discovered the relationship between mechanical energy and heat energy which led to “Law Of Conversation” which states that energy cannot be created nor destroyed but can be converted from one form to another. Energy…
