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

  9. 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

  10. 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
