  1. DeVry University Professor Noah Horwitz Jean King, Igor Kukharenko, ThilangaIndrasena Brian Dixon, Amy Dobs WIRELESS COMMUNICATION

  2. What is wireless networking? • System used for communication over radio waves • Used for: • Conversation • Email • Transmitting audio and video • GPS location services • Browsing the internet • Also used for communication between computers

  3. Wireless networks basics • Functions on grids dividing cities or regions into smaller sections or cells • Cells use radio frequencies to provide service to a particular area • A wireless antenna at each cell base station links callers to the phone, internet, or some other network

  4. Wireless network basics (cont’d) • Looks for signal confirming service • Weaker signals are passes off to antenna with stronger signal • A wireless antenna at each cell base station links callers to the phone, internet, or some other network

  5. History of Wireless Communications • First wireless communication networks used in pre-industrial age • 1838 - Samuel Morse invented telegraph • Government licensing began and first amateur transmitter set up in 1909 • 1985 FCC authorized use of ISM bands for public use allowing development of wireless LAN

  6. Cellular History • First mobile telephone service introduced to public in 1946 • 1950’s and 1960’s Cellular concept was developed by AT&T Bell Laboratories • 1983 First analog cellular system introduced • 1984 FCC increased spectral allocation for cellular use • 1990’s Second generation cellular phones

  9. Government Role • Administration of President Clinton • FCC and their approval of wireless frequencies • Wi-Fi and it’s effect on economy.

  10. Network • LTE network Progress • Comcast as Internet Provider • Network Traffic control by Comcast • AT&T legal conflict with Google • Google Violations

  11. Health Effect/Danger • Radiation from use of cellphone • Non-ionizing radiation • Doctor Devra Davis conclusion

  12. Psychological Consideration and Media Influence By Thilanga Indrasena

  13. Psychological Effects • Development of this technology • Human interaction to this technology • Psychological needs of this technology

  14. Sociological Effects • How this technology has change our society • What has led this technology to develop • Who will benefit from this technology

  19. The Studies and Standards • World Health Organization • International Commission on Non-Ionizing Radiation Protection • Federal Communications Commision • Claims of Safety with the Current Standards • Bio-Initiative Working Group • Studies showing toxic effect from Cell Phone use Google images

  20. Skepticism: Apple iPhone 4 "When using iPhone near your body for voice calls or for wireless data transmission over a cellular network, keep iPhone at least 15 mm (5/8 inch) away from the body, and only use carrying cases, belt clips, or holders that do not have metal parts and that maintain at least 15 mm (5/8 inch) separation between iPhone and the body" Warnings From Manufacturers BlackBerry 9000 “the radio-frequency energy exposure by carrying the phone outside a holster and within 0.98 inches (2.5 cm) of your body violates the Federal Communication Commissions guidelines.” Scherer,M, 2010 Scherer,M, 2010 Motorola W180 “keep the active device one full inch away from their body, if not using a company-approved clip, holder, holster, case or body harness."
