Unlike the GSM protocol, the DECT network specifications do not define cross-linkages between the operation of the entities ( for example, Mobility Management and Call Control ).

DECT is also used as a private, non-networked, cordless phone system where its low power profile ensures that nearby DECT systems do not interfere with each other.

Most consumer-level DECT phones and base stations support the GAP profile, even those that do not publicize the feature, and thus can be used together.

The " 6. 0 " in DECT 6. 0 does not specify a spectrum band, but is a marketing term coined by Rick Krupka, Product Director with Siemens, for DECT devices manufactured for use in the U. S. and Canada.

Like DECT, DECT ULE standard uses the 1. 9 GHz band so suffers less interference than Zigbee, Bluetooth or Wi-Fi, which all run on 2. 4 GHz.

The original DECT frequency band ( 1880 MHz – 1900 MHz ) is used in all countries in Europe.

In the United States, the Federal Communications Commission in 2005 changed channelization and licensing costs in a nearby band ( 1920 MHz – 1930 MHz, or 1. 9 GHz ), known as Unlicensed Personal Communications Services ( UPCS ), allowing DECT devices to be sold in the U. S. with only minimal changes.

DECT operates in the 1880 – 1900 MHz band and defines ten channels from 1881. 792 MHz to 1897. 344 MHz with a band gap of 1728 kHz.

The recently allocated 1. 9 GHz band is used by the popular DECT phone standard and is considered more secure than the other shared frequencies.

The recently allocated 1. 9 GHz band is reserved for use by phones that use the DECT standard, which should avoid interference issues that are increasingly being seen in the unlicensed 900 MHz, 2. 4 GHz, and 5. 8 GHz bands.

* Frequency: in Europe, in China, in Japan, in Latin America and in the US and Canada, and products may NOT be used in the UK or Ireland as they cause and suffer from interference with the UK and Ireland cellular networks with illegal use of such products being prohibited by UK agencies, and UK and Ireland DECT and products may NOT be used in the US and Canada as they cause and suffer from interference with US and Canada cellular networks and aircraft and for that reason is deemed illegal to use by US and Canadian agencies such as the Federal Communication Commission and Industry Canada.

There are also other devices such as some baby monitors utilizing DECT, and in these devices there is no gateway functionality.

The DECT and DECT 6. 0 technologies are essentially identical, except for operating frequency.

DECT 6. 0 products Do not support " GAP ", therefore phones of differing brands are not guaranteed to work together.

The standard has been created to enable home automation, security, healthcare and energy monitoring applications that are battery powered and can easily connect to the web using the large number of existing DECT enabled modems and be managed using a smartphone app.

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, are able to interoperate for basic calling.

The DECT standard includes full testing suites for GAP, and GAP products on the market from different manufacturers are in practice interoperable for the basic functions.

Exceptions to this include the DECT and PHS micro-cellular systems, UMTS-TDD UMTS variant, and China's TD-SCDMA, which use Time Division duplexing, where different time slots are allocated for the base station and handsets on the same frequency.

Headsets are also available with 2. 5mm jack sockets for many DECT phones and other applications.

These are available in Code Division Multiple Access ( CDMA ), Digital Enhanced Cordless Telecommunications – DECT ( TDMA / DCA ) ( See ETSI 6 EN 300 765-1 V1. 3. 1 ( 2001-04 ) -" Digital Enhanced Cordless Telecommunications ( DECT ); Radio in the Local Loop ( RLL ) Access Profile ( RAP ); Part 1: Basic telephony services "), Global System for Mobile Communications ( GSM ), IS136 Time Division Multiple Access ( TDMA ) as well as analog access technologies such as Advanced Mobile Phone System ( AMPS ), for which there will be independent standards defining every aspect of modulation, protocols, error handling, etc.

While the GSM EDGE standard (" 2. 9G "), DECT cordless phones and Mobile WiMAX standards formally also fulfill the IMT-2000 requirements and are approved as 3G standards by ITU, these are typically not branded 3G, and are based on completely different technologies.

DECT SMS handsets are also preprogrammed for Eircom's SMSC.

Digital audio wireless systems using DECT, are resistant to interference and have a range up to 300 m.

Operates clearly in common congested domestic radio traffic situations, for instance, generally immune to interference from other DECT systems, Wi-Fi networks, video senders, Bluetooth technology, baby monitors and other wireless devices.

With good range ( up to 200 m indoors and 6 km using directional antennae outdoors ), dedicated spectrum, high interference immunity, open interoperability and data speeds of around 500 kbit / s, DECT appeared at one time to be a superior alternative to Wi-Fi.

AMULET3 was employed in a commercial prototype DECT device because of its inherent low electromagnetic interference characteristics.

This forced development of a variation of DECT, called DECT 6. 0, using a slightly different frequency range ; the technology is nearly identical, but the frequency difference makes the technology incompatible with systems in other areas, even from the same manufacturer.

DECT handsets and bases from different manufacturers typically work together at the most basic level of functionality: making and receiving calls.

Since the onset of the migration from TDM PBXs to VoIP and VoIP hybrid solutions, manufacturers such as Lantiq, Ascom Wireless Solutions, Aastra Technologies, Philips, snom and Polycom have developed IP-DECT solutions where the backhaul from the base station is VoIP ( H. 323 or SIP ) while the handset loop is still DECT.

PHS is essentially a cordless telephone like DECT, with the capability to handover from one cell to another.

A study of bedroom exposure in 2009 showed the highest ELF-EF from bedside lights and the highest ELF-MF from transformer devices, while the highest RF-ELF came from DECT cordless phones and outside cellphone base stations ; all exposures were well below International Commission on Non-Ionizing Radiation Protection ( ICNIRP ) guideline levels.

The highest typical daily exposure, according to a study of 2009, came from cellphone base stations, cellphones and DECT cordless phones, with the highest exposure locations in trains, airports and buses.

In Europe the power limit laid down for use of the DECT spectrum ( 250 mW peak ) was expressed in ERP, rather than the more commonly used EIRP, permitting the use of high-gain directional antennas to produce much higher EIRP and hence long ranges.

PBX networking vendors such as Cisco promote the adoption of handsets that use VoIP over local Wi-Fi as the replacement for DECT, but this imposes significant overhead on the design and complexity of the Wi-Fi network in order to provide roaming, coverage and reservation of bandwidth, not to mention quality of service.

Other interoperability profiles exist in the DECT suite of standards, and in particular the DPRS ( DECT Packet Radio Services ) bring together a number of prior interoperability profiles for the use of DECT as a wireless LAN and wireless internet access service.

These most commonly use digital technologies like DECT, 2. 4 GHz unlicensed spectrum, or 802. 11a / b / g standards-based wireless LAN technology.

* GSM Interworking Profile ( DECT ): a DECT profile allowing GSM handsets to use DECT base stations.

CT2's successor, DECT, was provided with an interworking profile, GIP so that GSM networks could make use of it for microcellular access, but in practice the success of GSM within Europe, and the ability of GSM to support microcells without using alternative technologies, meant GIP was rarely used, and DECT's use in general was limited to non-GSM private networks, including use as cordless phone systems.

Digital Enhanced Cordless Telecommunications ( Digital European Cordless Telecommunications ), usually known by the acronym DECT, is a digital communication standard, which is primarily used for creating cordless phone systems.

In January 2011 a low power variant ( DECT ULE-ultra low energy ) was discussed at the DECT World and CAT-iq Conference with a whitepaper presented by Sitel ( Now Dialog ) Semiconductor.

The first successful interoperability tests were announced by the DECT Forum in June 2011.

The public access application did not succeed, since public cellular networks rapidly out-competed DECT by coupling their ubiquitous coverage with large increases in capacity and continuously falling costs.

The DECT standard was developed by ETSI in several phases, the first of which took place between 1988 and 1992 when the first round of standards were published.

DECT was developed by ETSI but has since been adopted by many countries all over the world.

The protocol capabilities built into the DECT networking protocol standards were particularly good at supporting fast roaming in the public space, between hotspots operated by competing but connected providers.

XDECT R is a Uniden technology for extending the range of DECT phones ( apparently indefinitely ) by using multiple repeater stations.

* DECT Standard Cipher, an encryption algorithm used by wireless telephone systems

corDECT is a wireless local loop standard developed in India by IIT Madras and Midas Communications ( www. midascomm. com ) at Chennai, under leadership of Prof Ashok Jhunjhunwala, based on the DECT digital cordless phone standard.

Current cordless telephone standards, such as PHS and DECT, have blurred the once clear-cut line between cordless and mobile telephones by implementing cell handover, various advanced features, such as data-transfer and even, on a limited scale, international roaming.

DECT is used by many businesses to deploy private license-free microcellular networks within large campuses where wireline phone service is less useful.

The Generic Access Profile ( GAP ) ( ETSI standard EN 300 444 ) describes a set of mandatory requirements to allow any conforming DECT Fixed Part ( base ) to interoperate with any conforming DECT Portable Part ( handset ) to provide basic telephony services when attached to a 3. 1 kHz telephone network ( as defined by EN 300 176-2 ).

It is used by DECT, Bluetooth, Cypress WirelessUSB, Nordic Semiconductor, Texas Instruments LPRF, z-wave and Wavenis devices.
