    1. The DECT Standard Presented by Dr. Heinz Ochsner, Secretary DECT Forum

    2. Agenda How it all started Activities in ESPA and ECTEL TDMA vs. FDMA ETSI Achievements so far What is DECT ? Key parameters Key applications Its position Capabilities today and evolution The DECT Forum Its history Its achievements Outlook DECT is 3G

    3. Some History Activities started 1986 in ESPA (European Selective Pager Association) 1987: Many key events: EC Green Paper on Common Market „Battle of technologies“ CEPT decides on frequency band and radio access technology 1988: newly created ETSI takes over activities 1992: first set of standards approved 1993: first products hit the market 1995 until now: Constant extension of features: DECT / GSM Integration Medium and high data rates Packet mode Messaging SMS, EMS, MMS DECT / 3G Integration

    4. TDMA vs. FDMA

    5. DECT: What is it at all? Unlicensed use Optimised for Inhouse communications Cellular structures to cover large complexes Uncoordinated applications Integrated voice-/data-applications Current data concepts had been included from the very beginning Most popular technology for private (as opposed to „provided“) services and applications

    6. DECT: A worldwide standard ... Adopted in more than 110 countries

    7. Cumulative Sales by Application

    8. DECT: Key Parameters TDMA/MC/TDD Access Method Original band 1880 to 1900 MHz, 10 carriers 1.152 Mbit/s gross modulated bit rate per carrier with standard modulation 3.456 Mbit/s gross modulated bit rate per carrier with enhanced p/8 D8PSK modulation 10 ms frames providing 24 time-slots 250 mW peak TX power Dynamic Channel Selection/Allocation Terminal-directed seamless handover High level of security

    9. DECT Timing

    10. High speed data Speeds between 24 kbit/s and 2098 kbit/s per direction available for packet and circuit switched use Wide variety of products from various suppliers already available commercially, more to be launched in 2002

    11. Areas of Applications

    12. Positioning of DECT data services DECT’s main role for providing data services will be in the local areaDECT’s main role for providing data services will be in the local area

    13. DECT Forum: Our Mission To create a favourable market environment for the global DECT industry Secure frequencies for DECT now and in the future Ensure technical evolution through co-operation with standardisation bodies Promote most recent developments DECT SMS / EMS / MMS DECT Multimedia DECT 2 Mbit/s DECT 3G Position DECT with respect to Bluetooth, WLAN, 3G, etc. Ensure product interoperability Create a platform for the exchange of knowledge

    14. DECT Forum: Achievements So Far DECT is recognised globally as the primary technology for cordless telecommunications DECT has frequencies secured on all continents DECT has been succesfully defended against PHS in its prime market Europe DECT is accepted as an IMT-2000 family member
