What is wireless networking? System used for communication over radio
waves Used for:
ConversationEmailTransmitting audio and videoGPS location servicesBrowsing the internet
Also used for communication between computers
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
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
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
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

SKEPTICISM :Warnings From Manufacturers
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"
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.”
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."
