Jeopardy Nowadays, almost every people have a cell phone, but ...

  1. 1. Jeopardy Nowadays, almost every people have a cell phone, but not many people know the exactly meaning for some of the cell phone terminology. 300 200 100 300 200 100 300 200 100 300 200 100 Data network Feature Basic
  2. 2. 100-1 <ul><li>Cell Phone </li></ul>
  3. 3. Answer <ul><li>A wireless telephone that sends and receives messages using radiofrequency energy in the 800-900 megahertz portion of the radiofrequency (RF) spectrum. </li></ul>
  4. 4. 100-2 <ul><li>Call Divert </li></ul>
  5. 5. Answer <ul><li>Enables you to divert incoming calls to another phone or answering service. </li></ul>
  6. 6. 100-3 <ul><li>Dual Band </li></ul>
  7. 7. Answer <ul><li>A feature on some wireless phones that allows the handset to operate using either the 800 MHz cellular or the 1900 MHz PCS frequencies. </li></ul>
  8. 8. 100-4 <ul><li>GSM </li></ul>
  9. 9. Answer <ul><li>Global System for Mobile Communications, GSM is a digital cellular phone technology based on TDMA that is the predominant system Europe, the Middle East, Africa, Asia and in parts of America and Canada. First introduced in 1991, the GSM standard has been deployed at three different frequency bands: 900 MHz, 1800 MHz and 1900 MHz. GSM 1900 is primarily deployed in North America. Named after its frequency band around 900 MHz, GSM-900 has provided the basis for several other networks using GSM technology. GSM uses narrowband TDMA which allows eight simultaneous calls on the same radio frequency. Along with CDMA and TDMA it represents the second generation of wireless networks. </li></ul>
  10. 10. 200-1 <ul><li>SIM Card </li></ul>
  11. 11. Answer <ul><li>A small printed circuit board that must be inserted in any GSM-based mobile phone when signing on as a subscriber. It contains subscriber details, security information and memory for a personal directory of numbers. The card can be a small plug-in type or sized as a credit-card but has the same functionality. The SIM card also stores data that identifies the caller to the network service provider. </li></ul>
  12. 12. 200-2 <ul><li>SMS </li></ul>
  13. 13. Answer <ul><li>The transmission of short alphanumeric text-messages to and from a mobile phone, fax machine and/or IP address. Messages must be no longer than 160 alphanumeric characters and contain no images or graphics. Once a message is sent, it is received by a Short Message Service Center (SMSC), which must then get it to the appropriate mobile device. </li></ul>
  14. 14. 200-3 <ul><li>Tri-Band </li></ul>
  15. 15. Answer <ul><li>A network infrastructure or wireless phone designed to operate in three frequency bands: 800 MHz, 900 MHz and 1800MHz. </li></ul>
  16. 16. 200-4 <ul><li>IrDA </li></ul>
  17. 17. Answer <ul><li>Infrared Data Association, A membership organization founded in 1993 and dedicated to developing standards for wireless, infrared transmission systems between computers. With IrDA ports, a laptop or PDA can exchange data with a desktop computer or use a printer without a cable connection. Like a TV remote control, IrDA requires line-of-sight transmission. IrDA products began to appear in 1995. </li></ul>
  18. 18. 300-1 <ul><li>Smart Phone </li></ul>
  19. 19. Answer <ul><li>A class of wireless phone handsets with many features, and often a keyboard. What makes the phone &quot;smart&quot; is its ability to handle data, not only voice calls. </li></ul>
  20. 20. 300-2 <ul><li>WAP </li></ul>
  21. 21. Answer <ul><li>Wireless Application Protocol, An open standard for communication between handsets and the Internet. WAP is a wireless communications environment for delivering web data to wireless terminals with minimal screen display. An initiative started by Unwired Planet, Motorola, Nokia and Ericsson to develop a standard for wireless content delivery on the next generation of mobile communicators. WAP strips all but graphics for display on small screens, such as mobile phones. A mini-browser is an integral part of WAP enabled phones. WAP enabled phones first appeared in Europe at the end of 1999. </li></ul>
  22. 22. 300-3 <ul><li>WIN </li></ul>
  23. 23. Answer <ul><li>Wireless Intelligent Network, The architecture needed to match the capabilities of the wireline intelligent network. In addition to transparent roaming, selective call screening, short message service and pre-paid billing are features that a WIN can provide. </li></ul>
  24. 24. 300-4 <ul><li>3G </li></ul>
  25. 25. Answer <ul><li>A new wireless standard promising increased capacity and high-speed data applications up to two megabits. Third generation wireless employ wideband frequency carriers and a CDMA air interface. Networks must be able to transmit wireless data at 144 kilobits per second at mobile user speeds. Implemented in Europe as UMTS and CDMA2000 in North America, its goals are high-quality multimedia and advanced global roaming (in house, cellular, satellite, etc.). </li></ul>
