this technology was adapted to the larger market of Local Area Networks (LANS). This Wireless LAN technology is described by the 802.11X specification family which is an extension of the IEEE 802 LAN/MAN standards‚ published by the Institute of Electronics and Electrical Engineers (IEEE). Adopted by the IEEE in 1997‚ the 802.11X specification has been updated to accommodate the advances in wireless LAN technology. The original 802.11 specification detailed a technology that provided a rather

bad performance. By the time the second wave of hardware was available‚ 802.11b had so many users that it didn’t make sense to switch for most users who had just finished stabilizing their networks. The next protocol to hit was 802.11g‚ which the IEEE ratified in 2003. 802.11b users were starving for faster speeds by this time‚ but due to compatibility issues‚ had not switched to 802.11a which had a much smaller hardware base. 802.11g was the answer to all of

A wireless LAN or WLAN is a wireless local area network‚ which is the linking of two or more computers without using wires. It is the same as LAN‚ but has a wireless interface. WLAN utilizes spread-spectrum technology based on radio waves to enable communication between devices in a limited area‚ also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network. Wireless Local Area networks (WLANs) have been employed

A wireless LAN or WLAN is a wireless local area network‚ which is the linking of two or more computers or devices without using wires. WLAN uses spread-spectrum or OFDM modulation technology based on radio waves to enable communication between devices in a limited area‚ also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network. For the home user‚ wireless has become popular due to ease of installation‚ and

The IEEE-30 bus system is used throughout this work to describe the proposed approach. It consists of six generating units‚ 41 transmission lines‚ 4 tap changing transformers and two VAR sources. The generator‚ bus‚ line‚ cost and emission data of the IEEE-30 bus system is taken from [27]. The one line diagram of this system is shown in Figure 5.1. The detailed system parameters are presented in the Appendix Tables A.1.Throughout all cases‚ the IEEE-30 bus system base MVA has assumed to be 100 MVA
