Bluetooth and UWB to be Interoperable

“The Bluetooth Special Interest Group, a 3,400-member group whose backers include     Nokia Corp., Motorola Corp. and Intel Corp., said it has begun working with two industry bodies developing rival versions of the technology commonly referred to as ultra-wideband, or UWB.

The discussions with the WiMedia Alliance and the UWB Forum are very preliminary, so it is unclear whether the collaboration will produce an integrated platform combining Bluetooth with UWB. There are also issues such as UWB regulatory approvals and signal interference with other wireless technologies that need resolution.”

UWB May Arrive Too Late to Matter

The U.S. market for Ultra Wideband (UWB) – multispectral wireless solutions for short-range/high-speed data transmissions (200 Mbps or higher at 10 feet) – is expected to face several obstacles onthe road to mass deployment. According to new insights from The Diffusion Group, the next generation of 802.11 solutions will hit the market sooner than mainstream UWB solutions and be able toleverage the large embedded base of 802.11x products and widespread market awareness.  Read more...

WiFi To Stay Dominant In Home Entertainment

From ABI Research’s press release:

Technologies for networking home entertainment equipment will compete for dominance over the next five years, but ultimately Wi-Fi will use 802.11n to continue its early lead, according to a new study by ABI Research.

The report, “Wi-Fi Home Entertainment Networks,” identifies three candidates for wireless home entertainment networking: powerline networking, Wi-Fi (802.11x) and Ultra Wide Band (UWB). ABI Research believes that the real contest will be between Wi-Fi and UWB.

Phil Solis, ABI Research senior analyst, points out that although the official data transmission rate of the 802.11a and 802.11g protocols is 54 Mbps, the actual throughput is only about half that, due to the communications overhead required.  Read more...

Ultrafast Wireless Technology Introduced

Wi-Fi aficionados have nothing to worry about: UWB’s highest rate works only within 3 feet. At 30 feet, throughput drops to about 110 mbps. Nevertheless, UWB could become a building block of several new, limited-range standards such as Wireless USB and the next generation of Bluetooth. Even though UWB is currently embroiled in an industry standards battle (surprise), backers hope to solve all legal and technical issues by year-end. That would clear the way for early products such as set-top boxes that send signals to UWB-equipped TVs, and digital cameras that transmit images wirelessly and quickly.

New Wireless Protocol Offers Greater Speeds

The industry group called the Multiband OFDM Alliance, which is led by Texas Instruments Inc (TI), said Monday that it would publish final standards for the technology in May.

Products using the new technology should be available in 2005 the group said.

According to the MB OFDM Alliance, ultra wideband or IEEE 802.15.3a operates with less power than today’s wireless protocols but is capable of much higher speeds, upwards of 200Mbps, and of streaming TV-quality video.

The group announced on Monday that there are now over 50 member companies in the alliance. Over 15 new member corporations have joined in the last two months.  Read more...
