D2 Technologies is shipping a WiMAX mobile-phone reference design based on Linux, with Google Android and Windows CE/Mobile flavors to follow in Q2. The "dual-mode" design can mix and match WiMAX, WiFi, and cellular radios, and uses a Texas Instruments OMAP-based processor. D2, an embedded IP communications software firm that has offered Linux-ready VoiP stacks for WiFi-enabled smartphones, says that it will privately demonstrate the reference design this week at ITExpo East 2009 in Miami. The design is said to be a turnkey solution for handsets and "similar portable devices" that combine any two of the following radios: WiMAX, WiFi, and cellular. The OMAP3 chips are available with or without a built-in TI DSP (digital signal processor). We're guessing the design eschews a hardware DSP, since it is said to include D2's softDSP VoIP engine. Also included is D2's mCUE mobile client stack (diagram below), along with codecs, error correction, jitter buffer, and a host of other VoIP technology, says the company. The design reportedly supports standard IMS-SIP, along with an alphabet soup of more proprietary VoIP technologies. mCUE features are said to include:- Presence-based and push-to-x controls
- Cellular and VoIP calls (though cellular likely not used in this design)
- PBX feature activation
- IM, email, and SMS
- Interoperability with communications services like IP PBXs and UC systems
- Interoperability with commercial "VoIM" services like Google Talk, Yahoo!, MSN, and AIM
- Customizable UI elements, including contacts address book with presence (see image at top) and IM chat
