      Roads Diverge to Wireless Net Service Quality
      Engineers hammering out a quality-of-service (QoS) standard for 802.11 networks have agreed to disagree by writing two distinctly different mechanisms into a draft standard that could be ratified early next year. Computer industry companies such as Intel and Microsoft have rallied support for Enhanced Distributed Channel Access (EDCA), a best-efforts mechanism in which devices negotiate for bandwidth based on up to eight levels of priority using traditional 802.11 probabilistic methods. A group consisting of Atheros Communications, Cisco Systems, Intersil and others has already defined a subset of the pre-standard EDCA features, called Wireless Multimedia Enhancements, and implemented it in products. Consumer OEMs and some carriers argue that the scheme does not provide the bandwidth and latency guarantees they need for glitch-free voice, music and video. They are lobbying for a polled-access scheme, broadly known as the Hybrid Coordination Function, in which access points regularly poll and grant devices exclusive access to an 802.11 channel in a more deterministic fashion.

      AT&T Wireless Sets Messaging Records

      AT&T Wireless said TV show American Idol created what it calls the “largest text-messaging event by a single carrier worldwide.” More than 7.5 million American Idol-related messages were sent by the carriers subscribers during the shows season, the carrier said. The carrier also said one-third of the participants had never sent a text message before over its network, that the number of text votes increased by nearly 5,000 percent from the first episode to the last, that 70 percent of the text voters voted more than once, and that 2,300 text messages per second were sent at one point.

      Sybase Invests $25 Million in Wi-Fi Application Development

      Sybase plans to invest $25 million over the next year to make using public wireless LAN networks more cost-effective and reliable for accessing enterprise applications, the company announced Tuesday. Sybase will invest some of that $25 million in building a network of competency centers for Wi-Fi research, the first of which will be hosted at the University of Waterloo, in Waterloo, Ontario. The company also intends to collaborate with its software development partners to embed Sybase technology in their applications for mobile devices.
