DECT Stack and Application Development

Raycomm can provide solutions to:-

• Develop applications that get the most from DECT technology
• DECT voice and data applications e.g. DECT networking, modem, messaging
• Design DECT products to take full advantage of DPRS (Dect Packet Radio Service)
• MAC, DLC, NWK, IWU, MMI and application layer development or modification
• Integrate DECT capability into products and systems
• DECT stack porting to any BMC architecture

DECT is aimed at medium-range, voice and data applications - particularly in SOHO applications. It is a proven mature technology and with that comes stability and enhanced build cost effectiveness. Accepted and used globally around the world, DECT standards are continually being pushed forward by ETSI with features such as the introduction of DPRS, giving data rates up to 2Mbps. For the future, ETSI are looking toward data rates of 20 Mbps.

We have several years of experience specifically developing within the DECT protocol itself and developing DECT products for various markets. DECT is tried and tested, very capable and a highly flexible technology suitable for voice and data applications.

We can analyse your intended requirement, suggest how DECT can be used and highlight any operational restrictions that may apply at an early stage and make sure that DECT is right for you.

We have extensive experience developing within all levels of the DECT protocol stack itself and more latterly developing applications which use the full benefits of the technology both in voice and packet data applications.

There are three main possibilities for the distribution of the DECT stack on your hardware:

1. The complete DECT protocol stack and your application sit together on the Burst Mode Controller (BMC). This method is generally suited to small to medium sized applications.

2. The lower layers of the protocol stack reside on the BMC whilst the application layer resides on a separate processor, PC or similar platform. This may be suitable for small systems or wireless modem applications for example.

3. For a system intended to cover a wide area then the MAC and physical layers will usually be distributed to form cells, with each MAC/Physical layer feeding back to a common central data link controller and the higher layers. This method is necessary if seamless handover is required between individual cells. More suited to applications such as wireless LAN or wide area voice coverage.

If interoperability with other manufacturer's products is a necessity your application will need to integrate with one or more of the official DECT voice and data profiles, otherwise a bespoke profile can be developed to best suit your application. We can design your DECT application, create the required profile(s) and integrate with a third party DECT stack.

DECT stacks are reasonably cheap these days hence developing your own stack is not usually necessary, we have experience working with vendors of DECT hardware who provide a DECT protocol stack. In doing any required stack modifications we will work closely with the chosen hardware supplier.

The technology lends itself to data applications where rates of between 24Kbps and 2Mbps are required. We can develop bespoke applications consisting of voice, data or both, for markets such as wireless networking and internet access. Let us use our extensive experience to get your product to market.
