Digital Enhanced Cordless Telecommunications

DECT

DECT or Digital Enhanced (former European) Cordless Telecommunications is an ETSI standard for digital portable phones, commonly used for domestic or corporate use. DECT can also be used for wireless data transfers.

DECT is (like GSM) a cellular system. A major difference between the systems is the cell radius — DECT cells have a radius of 25 to 100 meters, while GSM cells are 2 to 10 km.

Some other DECT properties:

• net bit rate: 32 kbit/s
• frequency: 1900 MHz
• carriers: 10 (1880..1900 MHz)
• timeslots: 2 x 12 (up and down stream)
• channel allocation: dynamic
• traffic density: 10000 Erlangs/km²

DECT physical layer uses:

• Frequency division multiple access (FDMA),
• Time division multiple access (TDMA) and
• Time division duplex (TDD)
