Introduction This lab will introduce you to wireless spectrum analysis and supports this week’s TCO. TCO 7: Given a situation requiring a wireless network solution‚ propose an appropriate design for a wireless network using radio frequency based methods. Background Wireless signals are invisible to the human eye. To see these signals‚ a tool such as a spectrum analyzer is required. In this lab‚ you will learn how to use a common spectrum analyzer‚ as you would in your career‚ to locate potential

Principle of wireless network system The principle of wireless network system needs the tool to transmit and expand the signal or we call “Access Point” and it has PC Card. It is a LAN Card that use to connect to Access Point. It also use radio wave to transmit & expand the signal. It use frequency from 2.4 to 2.4897 GHz and it can choose the config in wireless lan. The distance of wireless connection Indoor 1) 50 meters able to speed about 1.1 Mbps 2) 80 meters able to speed about 5.5

What risks and safeguards are associated with wireless communication? What is “war driving” or “war flying”? Are you comfortable (or would you use) a wireless “hot spot” to do computer work? What safeguards might you use in accessing an unprotected (public) wireless communications? Are you more at risk using a wireless connection via laptop or a connection via a smart phone? Transmissions over wireless networks can be intercepted by any suitable device within the transmission radius. If a network

Abramson‚ a professor at the University of Hawaii‚ developed the world’s first wireless computer communication network‚ ALOHAnet (operational in 1971)‚ using low-cost ham-like radios. The system included seven computers deployed over four islands to communicate with the central computer on the Oahu Island without using phone lines. Definition A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio)‚ and usually
