Need Need for emergencies Need for location of user (jobs, business, etc.) Need for business calls Will be difficult to replace

Research

Shows that the cellular device emits radiation We cannot use the cellular device without radiation Radiation causes cancer

Development The history of mobile phones begins with early efforts to develop mobile telephony concepts using two-way radios and continues through emergence of modern mobile phones and associated services.mobile telephony mobile phonesassociated services Radiophones have a long and varied history going back to Reginald Fessenden's invention and shore-to-ship demonstration of radio telephony, through the Second World War with military use of radio telephony links and civil services in the 1950s, while hand-held mobile radio devices have been available since 1973.RadiophonesReginald FessendenSecond World War

Commercialization First commercialized in the 1980’s Motorola’s DynaTAC 8000x was recognized as the first commercial cellular phone Early cell phones were unique because they simply allowed people to communicate wirelessly in a vast area Consumers bought, Despite the cost

Consequences Upgrading to new cellular devices Parents purchasing have increased More children have cellular devices Videos, pictures, text messaging, games Miscommunication Addiction Lost signals

Demand Great tracking devices Has GPS Most people already have them

Demand GPS - The Global Positioning System (GPS) is a satellite- based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS.
