This document discusses wireless multimedia (WMM) and provides an overview of key concepts: - WMM allows for the transfer of multimedia content like text, pictures, video, and sound between devices without wires using radio waves. - It compares Bluetooth and Wi-Fi, noting they both use radio frequencies but Wi-Fi has greater range and speed while Bluetooth has lower costs. - Advantages of wireless include convenience, mobility, and productivity while disadvantages include potential security issues, slower speeds, reliability concerns, and limited range. The document then details common wireless security protocols like WEP, WPA, and WPA2 and how they work to encrypt data transmission between devices connected over wireless networks.

Wireless Multimedia
? Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor and doesn't has a cables between them. ? The wireless technologies use radio waves to transfer the data.
What is the difference between Bluetooth and Wireless? ? Both Wi-Fi and Bluetooth are wireless technologies that transmit data by using radio frequency (RF) signal, but the main differences between these two are range, speed, and cost

WEP The original encryption protocol developed for wireless networks. As its name implies, WEP was designed to provide the same level of security as wired networks. However, WEP has many well-known security flaws, is difficult to configure, and is easily broken.
WPA Introduced as an interim security enhancement over WEP while the 802.11i wireless security standard was being developed. Most current WPA implementations use a preshared key (PSK), commonly referred to as WPA Personal, and the Temporal Key Integrity Protocol (TKIP, pronounced tee-kip) for encryption. WPA Enterprise uses an authentication server to generate keys or certificates.
WPA 2 Based on the 802.11i wireless security standard, which was finalized in 2004. The most significant enhancement to WPA2 over WPA is the use of the Advanced Encryption Standard (AES) for encryption. The security provided by AES is sufficient (and approved) for use by the U.S. government to encrypt information classified as top secret ¡ª it¡¯s probably good enough to protect your secrets as well!
