DECT module adapts to the US market
Cordless voice module is now available with DECT 6.0 support, covering the 1920-1930MHz frequency band recently allocated in the USA for unlicensed personal communication services.
DECT transceiver sets Korean standard
RF device is one of the first DECT transceivers that operates in 1786 to 1803MHz frequency range defined for KDECT.
Providing a single, flexible platform for wired and wireless solutions, the kit allows manufacturers to quickly develop solutions while reducing their bill of materials by up to 30%.
The platform has a modular hardware architecture made up of a single motherboard plus a number of optional daughter boards.
This allows the main board to be configured for any of the three target applications.

Handsets developed by RTX using SiTel's single-chip DECT telephone silicon are among the first products to achieve the initial step towards full CAT-iq certification.
Software kit creates cordless applications
Kit provides a single basic stack and MMI that cover all current PSTN and future integrated access device cordless telephony applications.
Baseband lays foundation for integrated handsets
Heavyweight processing power enables cost-effective solutions for high-end cordless handsets, integrated access devices and wired VoIP telephony applications.
It also allows manufacturers to develop applications supporting DECT and/or Gbit Ethernet connections.
On the software side, the kit uses the industry-standard and royalty-free uCLinux operating system, which is complemented by a range of open-source applications, including a SIP stack and user agent, TCP/IP networking protocols, FTP and automatic provisioning.
Furthermore, the VoIP platform includes SiTel's own Natalie DECT protocol stack software.
This incorporates all industry-accepted cordless telephony protocols, including DECT, DECT 6.0, 2.4 and 5.8GHz and CAT-iq.
"We are delivering solutions like the VoIP development kit to enable our customers to create products with distinctive features while at the same time helping minimise their bill of materials as rising volumes of VoIP telephone shipments increase price pressures", said Mark De Clercq, Product Marketing Manager at SiTel.
"This development kit allows our customers to stay ahead of the pack by quickly and easily incorporating value-added features like DECT functionality - instantly turning desktop phones into hands-free DECT access points that can effectively provide businesses with a distributed wireless network architecture for free".
At the heart of the motherboard is a SiTel SC1445x baseband IC.
Thanks to a proven multicore architecture, the baseband can run the various VoIP codecs and acoustic echo cancelling while still having enough headroom for the TCP/IP networking stack and embedded SIP applications.
It also features a 32kHz analogue codec for wideband audio and a Class-D amplifier for hands free speaker phones.
In addition, the motherboard incorporates hardware to support features such as Power-over-Ethernet (PoE), a power adapter, a headset and a microphone.
Daughter board options include Ethernet, LCD screen and keypad, Foreign eXchange Subscriber (FXS), Foreign eXchange Office (FXO), WiFi and DECT radio modules.
The kit comes complete with a quick-start guide, schematics, Gerber files and all IC technical documentation, as well as extensive programming and software-development guides, plus SIP User Agent "how-to" documentation.
SiTel also offers its customers extensive design and production support.
This includes test plans, performance reports, design recommendations and guidance on the DECT and WiFi certification.
Originally developed for Enterprise solutions, the DECT standard has become prevalent with consumer applications.
