DECT stands for Digital Enhanced Cordless Telecommunications. Unlike analogue
cordless phones that used to be frequent in many homes and businesses around
the world, DECT is a digital wireless communication technology that is through
its advanced reliable infrastructure bound to make cordless phones even more
common in businesses and homes around the globe.
DECT formerly stood for Digital European Cordless Telecommunications standard.
This is because the technology involved was primarily developed by European
companies. It was changed to reflect the global acceptance of this cordless
telecommunications technology.
DECT uses TDMA which stands for Time Division Multiple Access, to transmit
radio signals, much the same as Global System for Mobile communication (GSM).
GSM is designed for mobile communications over longer distances, where as DECT
has been designed especially with short distances and large user numbers in
mind. Many of today’s modern cordless phones can operate in dual mode, giving
the user seamless DECT and GSM integration.
Below are five major applications of DECT cordless technology;
-
Cordless Private Branch Exchange (PBX) This allows companies to connect to a
wired telephone company and then re-distribute their calls over a DECT cordless
phone system through a radio antenna. Users could each have their own number
and make use of all the features of a fully functional PBX phone system. A DECT
cordless PBX phone system would be especially useful to companies or
organisations that have a large number of mobile employees, such as warehouses,
hospitals and building sites etc. It is even possible to convert a wired PBX
into a fully functional DECT cordless system with the addition of specialist
DECT equipment to your existing wired phone system.
-
Wireless Loop (WLL) Users in a neighbourhood typically served by a telephone
company wired local loop can be connected instead by a cordless phone that
exchanges signals with a neighbourhood antenna. A standard telephone (or any
device containing a telephone such as a computer modem or fax machine) is
simply plugged into a fixed access unit (FAU), which contains a transceiver.
The wireless Local Loop can be installed in an urban area where many users
share the same antenna.
-
Home Cordless Phones With the huge range of multiple handset, one cell DECT
systems on the market these days, people can install a single cell antenna
anywhere in their home and have a DECT cordless handset in each room.
-
Cordless Terminal Mobility The arrangement that is used by a lot of businesses
for their cordless PBX phone systems, could also be used by a service wanting
to provide cordless phone numbers for individual subscribers. This system in
general will provide less mobility than that of a GSM based system, which would
give it's users a greater range.
-
GSM/DECT Internetworking The DECT standard is able to interact with the GSM
standard, allowing users to move freely with a telephone from the outdoors (GSM
signals) into indoor environments (DECT signals). In the future many GSM
service providers will want to extend their services to support DECT signals
inside buildings. A dual-mode phone would automatically first search for a DECT
signal and then a GSM signal if DECT is not available.
