Topics of this course (3/3) Wireless Communication Technology Antennas and propagation Signal encoding techniques Spread spectrum Coding and error control Satellite communications

Wireless Comes of Age Guglielmo Marconi invented the wireless telegraph in 1896 Communications satellites launched in 1960s Advances in wireless technology Communication by encoding alphanumeric characters in analog signal Sent telegraphic signals across the Atlantic Ocean Radio, television, mobile telephone, communication satellites More recently Satellite communications, wireless networking, cellular technology

Broadband Wireless Technology Higher data rates obtainable with broadband wireless technology Graphics, video, audio Shares same advantages of all wireless services: convenience and reduced cost Service can be deployed faster than fixed service No cost of cable plant Service is mobile, deployed almost anywhere

Limitations and Difficulties of Wireless Technologies Wireless is convenient and less expensive Limitations and political and technical difficulties inhibit wireless technologies Lack of an industry-wide standard Device limitations E.g., small LCD on a mobile telephone can only displaying a few lines of text E.g., browsers of most mobile wireless devices use wireless markup language (WML) instead of HTML
