3. Background Information and History

4. Background and History What is DECT? D igital E nhanced C ordless T elecommunications DECT is a standard for digital wireless telephone technology DECT History developed January 1988 by the ETSI ETSI (European Telecommunications Standards Institute) developed DECT by combining CT2 and CT3

5. Background and History DECT was first known as D igital E uropean C ordless T elecommunications DECT changed to its current name to reflect global acceptance The first DECT was the Siemens Gigaset 900 telephone in 1992 First ETSI standards of DECT were ETS 300 175 and 300 176

6. Functionality

7. Functionality How Does DECT Function? It is high speed quality, low power technology Low risk of radio interference Uses t ime d ivision m ultiple a ccess (TDMA) to transmit the radio signals to DECT phones DECT phones work from a base station with a handset

8. Functionality 5 Major Applications of DECT 1) Cordless Private Branch Exchange (PBX) 2) Wireless Local Loop (WLL) 3) Cordless Terminal Mobility 4) Home Cordless Phones 5) GSM/ DECT internetworking

9. Usage In Society

10. Usage in Society Used for residential and business purposes DECT is used in many countries such as the U.S., Italy, and the U.K. In 2002 Bluetooth was created Bluetooth uses short range wireless data applications

11. Usage in Society DECT Solutions

12. Usage in Society Home Solutions Residential areas are the largest application area

13. Usage in Society Fax, PC, telephones, as well as PC and telephone wireless devices are connected by a fixed access unit PTSN- Public Switched Telephone Network PSTN access allows 6-10 handsets t be used externally and for intercom access

14. Usage in Society Office Solutions DECT capacity is high and supports more than 10.000 Erlang per floor square kilometer

15. Usage in Society Office Solutions Main application area for DECT is seamless handover No separate base station controller DECT is cost efficient

16. Usage in Society Enterprise Solutions Typical data services are paging, group calls, automatic alarms, and many others DECT provides laptop PC wireless access to LAN Provides cordless solutions for System Integrators

17. Usage in Society Public Solutions DECT provides high capacity WLL services

18. Usage in Society Public Solutions WLL supports voice telephony, ISDN, and internet user data This provides user access data up to a few hundred of kbps (kilobit per second)

19. Usage in Society Industrial Solutions DECT applications provide supervision and control needs in a variety of ways Authenticating - base station and handset handshake using specific rules and calculations Encryption - the digital data is encrypted and then is decrypted when it is received by the intended receiver

20. Future Outlook

21. Future Outlook The digital cordless telephone market is moving to new countries Use of DECT modules in security systems are replacing wired systems in buildings DECT security system applications will be used for homes DECT use for data/ multimedia on the web
