Η Intel μαζί με μία εταιρία ασύρματης δικτύωσης θα παρουσιάσει αυτή την εβδομάδα μία νέα τεχνολογία ασύρματης δικτύωσης. Πρόκειται για τεχνολογία που θα επιτρέπει στους φορητούς υπολογιστές της πλατφόρμας Centrino να συνδέονται με περιφερειακές συσκευές όπως πληκτρολόγια, ηχεία, headsets καθώς και με το iPhone. Η Intel και η Ozmo Devices θα παρουσιάσουν το Wi-Fi Personal Area Network (PAN) στην έκθεση Computex στο Ταιπέι. Το PAN θα γίνει πραγματικότητα τον επόμενο χρόνο ενώ αναμένεται να είναι μία σοβαρή απειλή για το Bluetooth.
Το Bluetooth χρησιμοποιείται ευρέως από χιλιάδες κατασκευαστές ηλεκτρονικών συσκευών για ασύρματη επικοινωνία μικρής εμβέλειας, αλλά παίζει σε διαφορετική συχνότητα από το Wi-Fi. Η παρουσίαση της Intel αναφέρει ότι ένας φορητός υπολογιστής θα μπορεί να είναι συνδεδεμένος σε ένα Wi-Fi access point και ταυτόχρονα μέσω του ίδιου πρότυπου να συνδεθεί με έως 8 περιφερειακές συσκευές, σε μικρή απόσπαση.

June 02, 2008 (Computerworld) Intel Corp. and a wireless start-up will demonstrate this week wireless short-range technology that enables Centrino-based laptops to connect to peripherals such as headsets, keyboards and stereo speakers, and even the iPhone.
Intel and Ozmo Devices in Palo Alto, Calif., will demonstrate the Wi-Fi Personal Area Network (PAN) technology Tuesday at the Computex trade show in Taipei.
The PAN technology, once it becomes a reality next year, “will definitely be a threat to Bluetooth technology,” said Jonathan Gruber, an analyst at In-Stat in Scottsdale, Ariz. Bluetooth is widely used by thousands of device manufacturers for short-range wireless communications within a range of about 30 feet, but runs on a separate radio from Wi-Fi.
Intel described the concept behind the Wi-Fi PAN at its April developer forum, and has posted a separate blog and video describing how its so-called Cliffside technology could allow a laptop user already connected to a Wi-Fi access point to also run up as many as eight wireless peripheral devices over Wi-Fi a short distance away.
The joint demonstration at Computex is the first time Ozmo has shown its integrated circuit, which acts as a transceiver for Wi-Fi and will be placed inside wireless peripherals that could begin shipping next year, said Ozmo CEO Dave Timm in an interview. Intel intends to provide software inside Centrino laptops, which account for the majority of laptops now shipping, to interoperate with the Ozmo integrated circuit.
Timm also said that Belkin International Inc. in Compton, Calif., has committed to building peripherals based on the new integrated circuit and provided a statement from a Belkin official confirming that company’s interest.
An Intel spokeswoman also confirmed that the company is collaborating with Ozmo. A statement from Randy Nickel, director of wireless marketing for Intel mobile platforms, noted how Ozmo’s technology will provide the ability to connect laptops via Wi-Fi to low-power peripherals without the need for a second radio as required with Bluetooth.
Timm noted that with Intel’s collaboration, the Wi-Fi PAN concept should grow, especially because more than half of the 100 million laptops shipping next year will run Intel’s Centrino chips.
Gruber said Intel’s involvement in the technology and its laptop dominance gives the technology credibility. “It will give Bluetooth a run for its money,” he said.
According to Ozmo, its new technology will cut down battery usage drastically, similar to rates of a Bluetooth device. Historically, Wi-Fi connections have been a big drain on device batteries, but Ozmo has patent-pending technology to reduce the drain, Timm said.
One area where a Wi-Fi PAN could make its biggest impact is with short-range connections to stereo equipment, since it would have the ability to send music uncompressed, as compared to compressed files sent via Bluetooth, Timm said.
A spokeswoman for the Bluetooth Special Interest Group, comprised of 10,000 members and founded in 1998, would not comment on the Ozmo announcement. The organization recently promoted its 10th anniversary and noted the widespread use of Bluetooth for a variety of peripherals, including hands-free technology for drivers who want to use cell phones while behind the wheel.
IDC analyst Ajit Deosthali said that he doesn’t think the Ozmo approach will be a threat to Bluetooth in the near-term, since the latter technology has been around so long and is entrenched as a means of supporting voice application for cell phones and headsets. “Wi-Fi over PAN is promising but has a lot of catching up to do,” Deosthali added.
Sales of hands-free technology are on the upswing, especially in states where new laws forbid using a cell phone while driving unless it is hands-free. In July, hands-free driving laws will take effect in California and Washington, adding those states to a growing group of states and cities that have already enacted similar laws.
