USA - D2 Technologies (www.d2tech.com), a specialist in embedded IP communications software platforms, is unveiling a new reference solution for mobile 4G Voice over LTE (VoLTE) in partnership with GCT Semiconductor (www.gctsemi.com), a leading designer and supplier of advanced 4G mobile semiconductor solutions.

This collaboration brings a complete, cost-effective turnkey design to market that is ideal for enabling OEMs and ODMs to quickly deliver smart phones, tablets and other mobile devices offering the speed and richness of the LTE network -- including VoLTE and Rich Communication Suite (RCS) video calling.

Visitors to International CTIA Wireless 2012, being held May 8-10 in the Ernest N. Morial Convention Center in New Orleans, can get a first look at the new reference solution in live video calls via the NVIDIA(R) Tegra(R) 3 quad-core mobile processor and reference tablet, running through the R&S(R)CMW500 LTE and IMS communication tester, in Rohde & Schwarz's exhibition space (Booth 2651).

"D2 Technologies and GCT continue to successfully work together," said Dr. Kyeongho "KH" Lee, President and Chief Executive Officer of GCT Semiconductor, Inc. "Wireless carriers are quickly moving toward LTE as their preferred 4G standard for the future, so by enhancing our partnership with companies such as D2 Technologies, our customers will be able to accelerate time-to-market for VoLTE devices utilizing the power of our field-proven and commercially deployed technologies."

The new reference solution brings together D2's mCUE(R) 4G, a converged 4G mobile communications client for VoLTE and RCS video calling, and GCT's GDM7240, a full band FDD-LTE single chip that supports all LTE frequency band classes and bandwidths. mCUE 4G is highly integrated and optimized for the Android(TM) OS platform and delivers today's most in-demand IMS communications features.

When paired with the award-winning GDM7240 and its powerful high performance processor, OEMs/ODMs can create mobile products that exceed today's consumer expectations, not just for VoLTE, but for higher speeds, global roaming and the delivery of enhanced, simultaneous applications.

"OEMs and ODMs are eager to enter the mobile marketplace with devices that include complete VoLTE functionality," noted Doug Makishima, chief operating officer for D2 Technologies. "By joining forces with GCT, we can offer a turnkey solution that delivers HD voice and real time video calls via a chipset with one of the industry's smallest footprints and the lowest power consumption, all without sacrificing the power and speed consumers demand."

About mCUE 4G D2 Technologies' mCUE 4G is the most advanced IMS IP communications software solution for the Android OS platform, supporting both the IR.92 VoLTE and RCS/RCS-e GSMA standards to deliver IP communications features like HD voice, real time video call, instant message, presence, SMS and VCC/CSFB on 4G mobile networks. As the first IP communications client deployed by a 4G mobile operator, it is field proven and delivers carrier-grade voice and video quality and demonstrated interoperability.

mCUE 4G is a complete communications client, providing all key layers from the UI and protocol stacks, a fully embedded media engine that includes a complete VoIP DSP module with wideband CODECs, and optimized video framework integration that supports native hardware video acceleration.

mCUE 4G supports application processors from companies such as Qualcomm(R), NVIDIA(R), Freescale(TM) Semiconductor, Marvell(R) and Texas Instruments Incorporated.

It features:

- IR.92 VoLTE and RCS/RCS-e standards compliance
- VoIP and SMS/MMS over IP
- IP video call and conference
- Seamless call handover with SR/DR-VCC and CSFB
- Complete UI with seamless user experience
- Optimized and portable Android framework integration

GCT's GDM7240 was recently named the best chipset/processor product in the LTE North America Awards 2011. It is an advanced LTE single-chip solution that is well suited to meet the rapidly growing demand for the faster delivery of multimedia-rich features as well as global roaming. It is currently commercially deployed with leading LTE operators in the U.S. and worldwide.

GDM7240 features:


- support for LTE Category-3 100 Mbps downlink, 50 Mbps uplink
- compliance with 3GPP Release 8
- support for all LTE frequency band classifications and bandwidths
- support for simultaneous use of up to four different RF bands (quad-band)
- advanced CMOS RF and single-chip SoC technology
