  1. 1. Mobile Devices Sun Kim HoJung Kim Mavvia Yuan Yuqi Ma
  2. 2. Index <ul><li>Introduction </li></ul><ul><li>The History of Mobile Devices </li></ul><ul><li>Types of Mobile Devices </li></ul><ul><li>Types of Mobile Operating Systems </li></ul><ul><li>The Future of Mobile Devices </li></ul>
  3. 3. Introduction <ul><li>Mobile Device? </li></ul><ul><ul><li>A pocket-sized computing device, typically having a display screen with touch input or a miniature keyboard </li></ul></ul>
  4. 4. history <ul><li>It can be said that the mobile devices was born at the same time the radio communication had been invented. </li></ul><ul><li>The development of mobile devices starts from the 1920's, there are five stages . </li></ul>
  5. 5. Stage One <ul><li>1920's-1940's </li></ul><ul><li>B ased on several wave bands of shortwave, the private mobile communication system had been invented. </li></ul><ul><li>The Detroit police car radio system is the representative one. </li></ul><ul><li>The frequency of this system is 2MHz at that time. In the 1940's the frequency had been risen to 30~40MHz. </li></ul><ul><li>It is considered as the beginning of the modern mobile service. </li></ul>
  6. 6. Stage Two <ul><li>1940's-1960's </li></ul><ul><li>The public mobile service came out . </li></ul><ul><li>1946 According to the plan of Federal Communications Commission(FCC) the Bell system established the first public car phone net in St.Louis. </li></ul><ul><li>There was three channles in that time, the mode was simplex. </li></ul>

  8. 8. Stage Four <ul><li>1970's-1980's ( the peak time) </li></ul><ul><li>The Bell Labs successfully developed the advanced mobile phone system(AMPS) </li></ul><ul><li>The cellular network built up, improved the capacity of the system. </li></ul><ul><li>The cellular network becames the utility system, used in the worldwide. </li></ul>
  9. 9. Stage Four <ul><li>Achivements in this stage: </li></ul><ul><li>microelectronic technique got a significant development which made the probability of miniaturization mobile devices be true. </li></ul><ul><li>The new system of mobile communication----cellular network </li></ul><ul><li>provide the technique for the manage and control of the large size net </li></ul>
  10. 10. Stage Five <ul><li>1980's- </li></ul><ul><li>The Digital Mobile Communication System(DMCS) gets developed and mature in this period. </li></ul><ul><li>AMPS & TACS stand for the Cellular Networks Ⅰ->analog system </li></ul>
