Qualcomm Inc. is sampling what it touts to be the first chipsets for dual-carrier HSPA+ and multi-mode 3G/LTE. The Mobile Data Modem (MDM) MDM8220 solution is the first chipset to support dual-carrier High-Speed Packet Access Plus (DC-HSPA+); and the MDM9200 and the MDM9600 chipsets are the industry's first multi-mode 3G/LTE solutions. The chipsets demonstrate progress toward enabling the mass-market commercial deployment of two next-generation network technologies that bring more advanced data capabilities to mobile devices for new global markets. Dual-carrier HSPA+ and LTE are network innovations that provide the ability to deliver more advanced data capabilities to mobile devices, supporting more compelling applications and richer user experiences.

Qualcomm's MDM8220 dual-carrier HSPA+ solution, based on the 3GPP Release 8 standard, provides peak downlink data rates of up to 42Mbit/s and 11Mbit/s on the uplink, allowing carriers to easily upgrade their existing infrastructure equipment to achieve significantly higher bandwidths. Its dual-carrier technology doubles networks' bandwidth from 5MHz to 10MHz by aggregating two HSPA carriers in parallel.

The MDM9200 and the MDM9600 chipsets are said to be the first multi-mode 3G/LTE solutions that allow UMTS and CDMA2000 operators to upgrade seamlessly to future LTE services while preserving backward compatibility to their existing 3G networks. MDM9200 supports UMTS, HSPA+ and LTE, while the MDM9600 supports CDMA2000 1X, EV-DO Rev. B, SV-DO, SV-LTE, UMTS, HSPA+ and LTE. All of the new chipsets support FDD LTE and TDD LTE modes and different carrier bandwidths, and are capable of using OFDMA and MIMO antenna technology to support peak data rates of up to 100Mbit/s on the downlink and 50Mbit/s on the uplink.

Many network operators, infrastructure vendors and mobile device manufacturers are working with Qualcomm to enable the deployment of these next-generation network technologies in new markets worldwide. Interoperability testing with infrastructure partners is already underway with multiple field trials scheduled for the first half of next year. Commercial launches of data-centric devices based on Qualcomm's MDM solutions are expected to begin during 2H 10.

"Qualcomm leads the industry in enabling next-generation mobile experiences with highly integrated, powerful and elegant solutions for dual-carrier HSPA+ and LTE. We are pleased to be working with so many industry leaders to bring these advanced technologies to market," said Alex Katouzian, VP of product management, Qualcomm CDMA Technologies. "We remain committed to CDMA and OFDMA WAN modem leadership and the seamless and cost-effective commercialization of next-generation technologies around the world."

Qualcomm is working with numerous network operators, infrastructure vendors and device manufacturers with its dual-carrier HSPA+ and/or LTE solutions. Among multiple network operators evaluating the new technologies are Japan's EMOBILE Ltd and Telstra Wireless. Qualcomm is also working with multiple infrastructure vendors, such as Huawei Technologies and Nokia Siemens Networks, to perform interoperability tests for dual-carrier HSPA+ and LTE. Among the many device manufacturers currently evaluating the new chipsets are Huawei, LG Electronics, Novatel Wireless, Sierra Wireless and ZTE.
