  1. A Gentle Introduction to Information and Communications Technology (ICT) HalimYanikomeroglu, PhD, PEng Professor Department of Systems & Computer Engineering Carleton University Ottawa, Canada

  2. Outline 1. Digital Communications: A Historical Overview 2. Case Study: Wireless Cellular Communications 3. ICT: Information and Communications Technologies

  3. From Research to Innovation Engineering in contemporary meaning: A fairly recent branch of knowledge 17th– 19thcentury: Calculus was developed 19th century, 2nd half: Engineering started being developed 20th century, 1st half: Mathematical principles of engineering got matured 20th century, 2nd half: Explosive growth in engineering applications 21th: Innovation (health care, productivity, environment, communications, education, …) R&D  R&D&I

  4. The Great Contributors to Info Theory and Communications Theory Claude Shannon 1916 – 2001 Bell Labs, MIT

  5. The Great Contributors to Info Theory and Communications Theory Ralph V.L. Hartley 1888 – 1970 Bell Labs Claude Shannon 1916 – 2001 Bell Labs, MIT • R.V.L. Hartley, “Transmission of Information”, Bell System Technical J, July 1928. • Formulated the law “that the total amount of information that can be transmitted is proportional • to frequency range transmitted and the time of the transmission.” • Considered as "the single most important prerequisite" for Shannon's theory of information.

  6. The Great Contributors to Info Theory and Communications Theory Ralph V.L. Hartley 1888 – 1970 Bell Labs Harry Nyquist 1889 – 1976 Bell Labs Claude Shannon 1916 – 2001 Bell Labs, MIT • R.V.L. Hartley, “Transmission of Information”, Bell System Technical J, July 1928. • Formulated the law “that the total amount of information that can be transmitted is proportional • to frequency range transmitted and the time of the transmission.” • Considered as "the single most important prerequisite" for Shannon's theory of information. • H. Nyquist, “Certain factors affecting telegraph speed”, Bell System Technical Journal, 1924. • H. Nyquist, “Certain topics in telegraph transmission theory”, Trans. AIEE, April 1928.
