SAN FRANCISCO—Fabless chip vendor Marvell Technology Group Ltd. Wednesday (Sept. 7) announced a single-LTE modem supporting several global wireless communications standards.
Marvell (Santa Clara, Calif.) said its PXA1801 combines support for FDD-LTE, TDD-LTE, HSPA+, TD-SCDMA and EDGE to deliver the highest data available in any given geography.
Weili Dai, Marvell's co-founder, said in a statement that PXA1801 is the first 2G/3G/4G modem with support for all of these standards. "I envision a time soon when a truly affordable global communications network helps to bring our world closer as consumers from every walk of life enjoy uninterrupted access to all services, applications and the worldwide cloud from any device they choose anywhere they roam," Dai said.
Marvell said PXA1801 is designed to deliver superior technical performance and extreme flexibility at a much lower cost of implementation. Widespread implementation of the world modem should both alleviate strained 3G networks and bring unprecedented service to a potential market of more than 2 billion new consumers, according to the company.
Expecting 3G to continue to play a prominent role in data communications for the next several years, Marvell has integrated advanced R8 WCDMA HSPA+ (42 Mbps DL) and R8 TD-SCDMA HSPA+ (8.4 Mbps DL) capability into PXA1801, ensuring that consumers have the highest performance access to their data regardless of infrastructure availability in any one location, the company said.
Marvell's LTE technology is designed to support the highest levels of performance available in the industry today with Category 4 throughputs of 150 Mbps DL (down link), according to the company.
From my point of view, I guess it use SDR tech to implement muli-mode/multi-frequency support, otherwise the cost is very high out of our mind.
Perhaps Marvell use some licensable IP or acquired some silence company we don’t know. Or just programmable multi-core HW accelerator cluster, plus task management MCU.
But we never hear any news about the license or acquirement, I predictor Marvell will merge Tensilica before, but not true.
But I think the real war is beginning for Marvell, because there is no any power consumption info, so perhaps the power is little big for them.
This article is just producing the news taken off from some financial network. Interesting details as to what processor is used and which interconnect it deploys and what is the RF processing engine is lacking.

Marvell is a bit late in the game.
The Gobi has all the Wireless radio (plus Wifi) protocols (and the upgraded version has LTE) plus a 12 channel GPS receiver. I have one in my Motorola Xoom.
The Israeli company ASOCS has developed a software defined radio chipset (potentially a chip) that can support all the above standards, any three concurrently, and is programmable for future baseband protocols.
