D2 Technologies and GCT Semiconductor Debut New Reference Solution for Mobile 4G VoLTE at CTIA Wireless 2012

May 08, 2012 — CTIA Wireless

New Orleans (CTIA 2012), San Jose and Santa Barbara, CA – May 8, 2012 — D2 Technologies, the market leader in embedded IP communications software platforms, is unveiling a new reference solution for mobile 4G Voice over (VoLTE) in partnership with GCT Semiconductor, Inc., 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® Tegra® 3 quad-core mobile processor and reference tablet, running through the R&S®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® 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 ™ 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.”
