DECT or Digital Enhanced Cordless Telecommunications is an ETSI standard for 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. Comparing DECT against GSM shows one major difference: the cell radius (25..100 meters for DECT, 2..10 km with GSM).

Here are some another DECT properties:

  • net bit rate: 32 kbits/s
  • frequency: 1900 Mhz
  • carriers: 10 (1880..1900 Mhz)
  • timeslots: 2 x 12 (up and down stream)
  • channel alocation: dynamic
  • traffic density: 10000 Erlangs/kmē

DECT physical layer use:

This means that the radio spectrum[?] is divided into physical channels into two dimensions: frequency and time.

Three application areas:

  • Domestic DECTs are connected to a base (radio fixed parts) connected to the PSTN. A base can accept more DECT
  • Business DECTs connected to PBX. Such a case, many radio fixed parts. The DECT dynamically connect to these (hand over feature)
  • Local loop (very rare). In this case, a DECT radio link replaces the normally wired connection between the final PSTN distribution point to the subscriber.

DECT GAP is an interoperability profile for DECT. The intent is that two different products from different manufacturers that both conform not only to the DECT standard, but also to the GAP profile defined within the DECT standard, should interoperate.
