DECT Hardware Modules

Several companies are now supplying DECT OEM modules, in some cases RF only and in others full RF and baseband modules for OEM products - handsets, basestations and other applications.  Amongst these are the companies listed below.  If you know of others, please advise us.  
DECT protocol software modules may be found on the Protocol Software page.   

Several companies also offer design services with licensing of designs - see our Design Solutions Page

Applications of DECT Modules
As well as telephones, DECT modules can be used to connect wirelessly a range of other information processing devices, such as a palmtop computer, enabling exchange of data, such as up-to-date schedules, calendars, and databases. Combined with telemetry or telematic systems, DECT systems can be used for the remote control of alarm and security systems for appliances such as  washing machines or cookers.    In the commercial environment DECT modules can be integrated into existing equipment or systems - for example enabling customers in a restaurant to pay for their meals with a credit card online at the table.

DECT Base System - consists of at least one Fixed Part (FP) and one Portable Part (PP) and works with a frequency and time multiplex process in the frequency range between 1.88 and 1.90 GHz. 10 frequencies each with 1.728 MHz are available for the transmission. Has up to 120 possible channels for this connection. Features: Great anti-interference security, High transmission power, High data rates possible, High eavesdropping and manipulation security, Range of max. 300 m in open space, Low power consumption, Minimal construction size.

Adaptations of the DECT base include: Point-to-point data transmission via UART, Speech transmission via PCM/ADPCM interface or Codec, Display controls, Measured value recording, measured value processing and data transmission, Integration into existing systems with various interfaces possible, Synchronous measured values recording (deviation ±10µs) at several stations.

Technical data, Data sheet pdf (78K), Firmware manual version 1.02 pdf (585K), Picture
A new 2.4 GHz variant for the North American market,  this module operates as low power frequency hopping device in the open 2400MHz band and complies with FCC part 15. 
Since the HW 86020 is fully interface-compatible with its DECT counterpart HW 86010, system integrators can easily adapt an existing DECT product to the US market.  Even though one feature of DECT – the exclusive frequency allocation – does not apply to the shared 2400 MHz band, all big advantages of the DECT protocol stack are also available with thE product.

MD32 DECT Engine
The Siemens MD32 DECT Engine was first shown at CeBIT99.   It promises to be both high quality and good value, given Siemens dominant position in the DECT marketplace, which should offer them good scale economies.  At CeBIT99 Siemens showed an application of the module in a palmtop computer.

The size of the MD32 DECT Engine  is 65x37x5 mm and it can be used for transmission of voice and data, with a 4-pin audio interface and RS232 serial port. All the data transport aspects are handled by the module, transported using the U-plane LU10 data service, guaranteeing  a BER of 10-8.

Gigaset DECT "Simcard" - World's Smallest DECT Engine
The new Siemens DECT engine is taking DECT into territory until now claimed by Bluetooth, in terms of form factor.  
Size 24 x 14 x 3.5 mm = 1.2 cc, one third the volume of its predecessor, the "Stamp"  (see below).
The new product is likely to be a hot topic when it goes on public display at this year's event, CeBIT 2000.  Clearly at this size the potential for integrating DECT short range links into PDAs, mobile phones, etc takes a big leap forward.
