  1. 1. Heather Buettner<br />TED 111<br />
  2. 2. DECT<br />Digital Enhanced Cordless Telecommunications<br />
  3. 3. Background Information and History<br />
  4. 4. Background and History<br />What is DECT?<br />Digital Enhanced Cordless Telecommunications<br />DECT is a standard for digital wireless telephone technology<br />DECT History<br />developed January 1988 by the ETSI<br />ETSI (European Telecommunications Standards Institute) developed DECT by combining CT2 and CT3<br />
  5. 5. Background and History<br />DECT was first known as Digital European Cordless Telecommunications<br />DECT changed to its current name to reflect global acceptance<br />The first DECT was the Siemens Gigaset 900 telephone in 1992<br />First ETSI standards of DECT were ETS 300 175 and 300 176<br />
  6. 6. Functionality<br />
  7. 7. Functionality<br />How Does DECT Function?<br />It is high speed quality, low power technology<br />Low risk of radio interference<br />Uses time division multiple access (TDMA) to transmit the radio signals to DECT phones<br />DECT phones work from a base station with a handset<br />
  8. 8. Functionality<br />5 Major Applications of DECT<br />1) Cordless Private Branch Exchange (PBX)<br />2) Wireless Local Loop (WLL)<br />3) Cordless Terminal Mobility<br />4) Home Cordless Phones<br />5) GSM/ DECT internetworking<br />
  9. 9. Usage In Society<br />
  10. 10. Usage in Society<br />Used for residential and business purposes<br />DECT is used in many countries such as the U.S., Italy, and the U.K.<br />In 2002 Bluetooth was created<br />Bluetooth uses short range wireless data applications<br />
  11. 11. Usage in Society<br />DECT Solutions<br />
  12. 12. Usage in Society<br />Home Solutions<br />Residential areas are the largest application area<br />
  13. 13. Usage in Society<br />Fax, PC, telephones, as well as PC and telephone wireless devices are connected by a fixed access unit<br />PTSN- Public Switched Telephone Network<br />PSTN access allows 6-10 handsets t be used externally and for intercom access<br />
  14. 14. Usage in Society<br />Office Solutions<br />DECT capacity is high and supports more than 10.000 Erlang per floor square kilometer<br />
  15. 15. Usage in Society<br />Office Solutions<br />Main application area for DECT is seamless handover<br />No separate base station controller<br />DECT is cost efficient<br />
  16. 16. Usage in Society<br />Enterprise Solutions<br />Typical data services are paging, group calls, automatic alarms, and many others<br />DECT provides laptop PC wireless access to LAN<br />Provides cordless solutions for System Integrators<br />
  17. 17. Usage in Society<br />Public Solutions<br />DECT provides high capacity WLL services<br />
  18. 18. Usage in Society<br />Public Solutions<br />WLL supports voice telephony, ISDN, and internet user data<br />This provides user access data up to a few hundred of kbps (kilobit per second)<br />
  19. 19. Usage in Society<br />Industrial Solutions<br />DECT applications provide supervision and control needs in a variety of ways<br />Authenticating- base station and handset handshake using specific rules and calculations<br />Encryption- the digital data is encrypted and then is decrypted when it is received by the intended receiver<br />
  20. 20. Future Outlook<br />
  21. 21. Future Outlook<br />The digital cordless telephone market is moving to new countries<br />Use of DECT modules in security systems are replacing wired systems in buildings<br />DECT security system applications will be used for homes<br />DECT use for data/ multimedia on the web<br />
