IntroductionChapter 1
TerminologiesSignal function having infoAnalog signal continuous signalDigital signal representation of discrete valuesFrequency number of occurrences of a repeating event per unit timeFrequency range A listing of the upper and lower limits of frequency limitsTelegraph long distance transmission of textual messages (wireless)Broadband wide bandwidth of a communication mediumIEEE Institute of Electrical and Electronics Engineers (425k members in 160+ countries)ITU International telecommunication union
Mobile and Wireless CommunicationMarconi invented the wireless telegraph in 1896Communication by encoding alphanumeric characters in analog signalSent telegraphic signals across the Atlantic OceanCommunications satellites launched in 1960sAdvances in wireless technologyRadio, television, mobile telephone, communication satellitesMore recentlySatellite communications, wireless networking, cellular technology
Broadband Wireless TechnologyHigher data rates obtainable with broadband wireless technologyGraphics, video, audioShares same advantages of all wireless services: convenience and reduced costService can be deployed faster than fixed serviceNo cost of cable plantService is mobile, deployed almost anywhere
Limitations and Difficulties of Wireless TechnologiesWireless is convenient and less expensive Limitations and political and technical difficulties inhibit wireless technologiesLack of an industry-wide standardDevice limitationsE.g., small LCD on a mobile telephone can only displaying a few lines of textE.g., browsers of most mobile wireless devices use wireless markup language (WML) instead of HTML
