Meru Radio Switches for the Enterprise WLAN
Meru Networks has launched a family of radio switches designed to support high-density data and VoIP mobility applications and to enable pervasive WLAN deployments in enterprise environments. Available in 4-, 8-, and 12-radio models, the radio switches layer up to 12 channels in a single coverage area. When deployed with a Meru controller, multiple radio switches coordinate to create virtual cells, blanketing large areas with up to a gigabit of wireless capacity, ideal for heavy usage and seamless roaming.
Meru Radio Switches are priced at $1,595 for the RS-4000, $2,995 for the RS-8000, and $4,195 for the RS-12000; www.merunetworks.com.

Virtual Platform Cuts Handheld Development Time
Virtio Corp.'s VPMX31 Virtual Platform replicates the full functionality of Freescale Semiconductor's high-performance i.MX31 and i.MX31L multimedia applications processors used in mobile phones, portable media players, and PDAs. It models all the components and peripherals required for early software development and software/hardware integration including the ARM1136JF-S core, power management and audio subsystems, the image processing unit, and memory controllers.
VPMX31 runs actual ARM11 binaries targeted for the processors—no cross-compiling is required. It also integrates with software development tools of choice such as ARM RealView and the GNU ARM toolchain. In addition, the product includes real-world connections through the host PC including Ethernet, camera, serial ports, LCD touch screen, COM ports, MMC cards, and keypad.
The VPMX31 is available both as a standard virtual platform and as a platform development kit, which includes authoring tools to customize platform hardware; for more information, visit www.virtio.com.
xMax Delivers Broadband over Radio Channels
xG Technology's xMax is an RF signaling technique designed to address the problem of low-frequency spectrum overcrowding. By combining elements of traditional narrow-band carrier systems with noninterfering elements found in low-power wideband systems, xMax delivers data rates orders of magnitude higher than Wi-Fi and other broadband approaches.
Unlike other wireless technologies that move most power from the carrier to the information-bearing sidebands, xMax places more than 99 percent of its power within a narrowband carrier while keeping its sideband energy at micropower levels. Typically -60 dB to -100 dB below the carrier, its information-bearing sideband, xG Flash Signal, can be as much as 100,000 times below the FCC's "Part 15" regulations.
xMax can be interleaved among existing RF channels, enabling operators to offer new services such as HDTV, video-on-demand, IPTV, and VoIP in an incremental fashion without interrupting existing services. In addition, the use of VHF and UHF bands eliminates the line-of-sight problems associated with high-frequency broadband approaches. The company claims that the technology will allow metropolitan area networks to deliver wireless backhaul to hotspots across an entire city from a single tower.
xG Technology recently conducted successful long-range field tests of xMax. Later this year, the company plans to release reference designs for sub-GHz fixed wireless base stations and consumer premise equipment based on current working prototypes. Visit www.xgtechnology.com for more information.
Sun Debuts Mobile Workstation
Sun Microsystems' Ultra 3 Mobile Workstation is designed to deliver the performance and functionality of a Sun Blade workstation in a mobile form factor. Available in 15- and 17-inch versions, the laptop features either a 550-MHz or 650-MHz UltraSPARC IIi processor or a 1.28-GHz UltraSPARC IIIi processor, up to 2 Gbytes of DDR RAM, 80-Gbyte IDE internal disk storage, and IEEE 802.11b wireless networking. It is preloaded with the Solaris 10 OS and the Java Desktop System, along with either StarOffice 7.0 or GNOME 2.0 Environment depending on the model.
The Ultra 3 Mobile Workstation starts at $3,400; www.sun.com.
Atmel and u-blox Offer GPS Weak-Signal Tracking
SuperSense is a new GPS weak-signal tracking technology that supports Atmel Corp.'s ANTARIS GPS chipsets and TIM-LH modules from u-blox AG. Designed to enable accurate GPS navigation in building interiors, deep urban canyons, covered roads, and other GPS-dead locations, the software targets mass-market automotive and handheld FCC E-911 Phase II-compliant GPS product applications.
SuperSense is available as a beta release when purchased with the SuperSense Evalkit or the TIM-LH GPS module; visit www.u-blox.com for more information.
Kingston Technology Launches SD Cards
Kingston Technology Company has expanded its line of secure digital memory cards with super-fast Ultimate SD cards optimized for digital cameras, MP3 players, and PDAs. Initially available in 512-Mbyte and 1-Gbyte capacities, the new cards offer 133X transfer rates, data retention of up to 10 years, a built-in write-protect switch to prevent accidental data loss, and low power consumption.
The 512-Mbyte Ultimate SD card costs $72, while the 1-Gbyte card costs $164; www.kingston.com.
WLANPlus Chipset Targets IEEE 802.11n Standard
To meet the demands of today's increasingly sophisticated wireless home networks, Metalink Ltd. has unveiled its WLANPlus chipset, which targets the emerging IEEE 802.11n standard for mulitiple-input, multiple-output (MIMO) applications.
The MtW8150 baseband device, combined with the MtW8150 radio-frequency IC, use 2 × 2 or 2 × 3 Real-MIMO technology to deliver data throughput up to 240 Mbps over the air along with advanced coding, channel bonding, and MAC aggregations to improve WLAN performance. The chipset can be embedded in digital video recorders, set-top boxes, HDTVs, media adaptors, and other consumer electronics products to enable seamless multimedia connectivity throughout the home.
