network design. Write a 1-2 page proposal for the research group explaining why that design would best meet their needs. For this question I would have to go with the WLAN Star topology‚ the main reason for using the WLAN is for your wireless users to be able to connect to the network via an access point. Other reasons for using a WLAN‚ you would be able to have the ability to have the pc’s connected via CAT 5 still connect to the network. Security is a big issue for your company‚ the purpose of that

have been established by international standards bodies and are used in almost all platforms and around the globe to ensure that all devices on the Internet can communicate successfully. IEEE 802.11 is a set of standards for implementing wireless local area network (WLAN) computer communication in the 2.4‚ 3.6‚ 5 and 60 GHz frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997 and has had subsequent

After conducting a study and analysis of the vulnerabilities of current Wi Fi Security industrial standards‚ we consider the possibility a new security architecture for Wi Fi which we call Wi Fi P+. Wi-Fi P+ is not a complex security architecture. It act as an additional security layer implemented over WPA/WPA2. It also implements some already available features that are not

I. Introduction It stands as perhaps the signal success of the computer industry in the last few years‚ a rare bright spot in a bubble-battered market. advances in wireless telecommunications technology are converging with Internet technology to foster new generations of applications and services. Presently‚ the United States and other countries are moving to third-generation (3G) and fourth-generation mobile telephony. The defining feature of these technologies is that transmission speeds

HOMEWORK WEEK 5 3. Compare and contrast the two types of antennas. There are mainly two types of antennas: omnidirectional‚ and directional. Omnidirectional antennas are installed on most WLANS with AP’s that have them. Omnidirectional antennas do just what they sound like‚ which is transmit data in all directions at the same time. The signal can go horizontally and vertically; and up and down. However‚ there can be a dead spot in a minute area directly above the antenna which has no signal.
