Introduction

• Cellular phones are portable/wireless
  communication devices.
• The cellular system uses many base stations to
  divide a service area into multiple 'cells'.
• Dr. Martin Cooper invented the first portable
  handset and made the first cellular phone call in
  April of 1973.
• Public trials began in Chicago in 1978 with 2000
  customers.
• By 1983 the first commercial analog cellular
  phone service was made available in Chicago.

Introduction

• Over the past two decades cellular phones have
  matured into versatile devices with millions of
  subscribers worldwide.

Cell Phone Dangers

• Cellular phones require a lot of power in order
  to emit radiofrequency energy at a high enough
  level to reach base stations that could be at
  distances of kilometers into the double digits.
• Two of the known health risks that this high
  energy device could impose are cancer caused by
  radiation emitted from the antenna and injury
  from a damaged or faulty battery.
• This presentation will deal with the dangers
  posed by the battery.

6
My Thoughts

• With the high demand for cellular phones
  companies have been releasing new phones very
  quickly.
• It is possible that many of these phones are not
  properly tested before being released in the
  market.
• Companies may not want to spend the extra money
  and time in developing safer phones.

7
Reasons For My Decision

• Recently there have been several cases of
  cellular phones spontaneously combusting.
• In some of these cases the user was seriously
  injured.
• My cellular phone spontaneously combusted.

8
Other Explanations for the Danger

• In many of these cases the victim was using
  unapproved accessories on their cellular phone.
• These include aftermarket batteries/chargers and
  signal boosting devices that are placed near the
  battery.
• Incidents are statistically extremely rare.

9
Conclusion

• If it was discovered that cellular phones are too
  dangerous to be used in their present form many
  companies would be put out of business or have to
  spend a lot of time and money to develop safer
  technologies.
• If something is not done millions of people could
  suffer the negative effects of cellular phone
  use.
• I was not using any unapproved accessories on my
  cellular phone.?
