Aggressive roadmap reveals breadth/depth of Direct Sequence-Ultra-Wideband solutions for consumer electronic (CE) applications
June 7, 2004 - Freescale Semiconductor, Inc., a wholly-owned subsidiary of Motorola, Inc., has detailed its current and next-generation UWB product family roadmap at the Wireless Connectivity (WiCon) World Expo in Amsterdam. Over the next year, Freescale plans to deliver three advanced UWB product families, including the industry’s first 1 Gbps UWB solution, to address the wide variety of performance and functionality required by numerous UWB applications.
Adding to the existing XtremeSpectrum™ chipset, which achieves over 110 Mbps, Freescale revealed that its planned UWB product families will be engineered to deliver 220 Mbps, 480 Mbps and 1 Gbps data transfer rates. Consistent with its current UWB offerings, the planned UWB families will be engineered to support peer-to-peer as well as ad hoc networking for truly mobile wireless connectivity. To address the demand for a low power, cost-effective UWB solution for handheld applications such as mobile phones, media players, digital cameras and camcorders, Freescale’s planned UWB product families will also be designed to integrate sophisticated power management tools to help extend battery life, a critical requirement for mobile applications.
The planned product families, which are to be designed to comply with the Federal Communications Commission's current Ultra-Wideband Report & Order, are scheduled to include driver support for multiple operating systems. The mini-PCI and SDIO module form factor are expected to enable integration into the smallest consumer electronics, while providing a variety of interfaces including PCI, mini-PCI, PCI-Express and USB2, and IEEE 1394.'The Freescale Media Access Control (MAC) chip is compliant with the IEEE 802.15.3 MAC protocol, while the Freescale PHY, which is based on the 802.15.3a DS-UWB proposal, provides data transfer rates ranging from 110 Mbps to 1Gbps. This support helps CE vendors to ensure interoperability among their product lines.
To date, Ultra-Wideband has been touted for consumer electronics products such as digital displays, DVD players, digital video recorders and set-top boxes, as well as handheld applications such as camcorders and digital cameras. New, high data rate applications are expected to emerge over the next three years and beyond that will further drive the need for products exceeding 1 Gbps data rates. For example, new media players that allow storage of multiple MPEG-4 movies will require 1 Gbps UWB solutions to upload/download the entire movie in just a few seconds. Portable hard drives are another emerging application, where users will want to use their hard drive at both the home and office. While transferring data from the portable hard drive to the host computer, a data rate of 1 Gbps is needed in order to keep other applications running during the continuous data transfers.
- The Freescale XtremeSpectrum UWB chipset with over 110 Mbps data rate has been sampling to customers worldwide and is expected to be commercially available Q3 2004.
- Freescale’s third generation, two-chip UWB solution, with data rates greater then 220 Mbps is expected to begin sampling Q4 2004.
- Freescale 480 Mbps and 1 Gbps UWB families are expected to begin sampling over the next year.
About Ultra-Wideband Technology
Ultra-Wideband is a wireless technology that transmits an extremely low power signal over a wide swath of radio spectrum. Unlike conventional radio systems that operate within a relatively narrow bandwidth, i.e. Bluetooth™ wireless technology, IEEE® 802.11b, IEEE 802.11a. Ultra-Wideband operates across a wide range of frequency spectrum by transmitting a series of very narrow and low power pulses. The combination of broader spectrum, lower power and pulsed data means that Ultra-Wideband causes less interference than conventional narrowband radio solutions, and delivers wire-like performance in an indoor wireless environment. This makes Ultra-Wideband technology ideal for consumer electronics applications that are increasingly multimedia-rich in content.
