System used for communication over radio waves
Used for:
Conversation
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
Samuel Morse invented telegraph
Government licensing began and first amateur transmitter set up in 1909

20. Radiation From Cell Phone Penetrating Human Skull
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
