(InfoWorld) - During a presentation at the IEEE Globecom 2006 Expo in San Francisco on Tuesday, Alan Crouch, director and general manager at Intel's Communications Technology Lab told the audience to expect Intel to put a pre-standard version of IEEE 802.11n Wi-Fi into its Centrino chips by next year. The IEEE 802.11n standard, which is not expected to be ratified before the first half of 2008, will give users far greater performance and range than current Wi-Fi technology. The technology will someday scale to 600Mbps, according to Bill McFarland, a member of the IEEE committee, with a range 50 percent greater than available with Wi-Fi now. Although the news caused barely a ripple of reaction in the audience of software and hardware engineers, there are industry analysts who have already warned large buyers of wireless technology to resist the temptation to deploy high speed IEEE 802.11n devices until the standard is ratified. This is the advice of Gartner's Ken Dulaney, among others, who said that a pre-standard version might be fine for the home where the technology exists as a closed loop, but in an enterprise with a heterogeneous wireless environment it could lead to interoperability problems down the road. Continuing on a theme of emerging technologies, Crouch also touted the benefits of UWB (Ultra Wideband), a short range, three meters, wireless technology, which he said will start to gain recognition in â07. UWB is sometimes called Wireless USB but with better performance. In addition, Crouch said the Bluetooth standards body will adopt UWB technology as a future version of Bluetooth. With its short range and high performance, first devices will be capable of 480Mbps, Crouch said consumer electronics companies will quickly take up the technology. Following Crouch on stage was David Leeper, senior principal engineer for UWB at Intel who continued to talk about UWB benefits and uses. "It is a compelling technology because you can do video streaming at very low power," Leeper said. Leeper estimated a full-length feature movie could be downloaded using UWB in 80 seconds. If UWB performs as advertised it could easily replace most interconnect cables such as those running to printers, scanners, and other peripheral devices allowing a user to print, stream wireless display data, and synch all at the same time. The capability to move a great deal of content at high speed also has a use in the enterprise, Leeper added. At the end of the Intel presentation, Crouch admitted that the biggest challenge faced by the industry is overcoming RF (radio frequency) interference among the various wireless technologies, especially Wi-Fi, WiMAX, and UWB. Crouch said each of the three technologies has a unique usage model and he does not expect any one of the three to replace the other.Crouch said, however, it wouldnât be easy to have a single device with all three radios inside. "Requirements for [using] multi-radio is a huge leap. This is where companies are spending their time and energy," Crouch said.ADVERTISEMENTNEW IT SERVICES FROM IBM: EASIER TO BUY AND IMPLEMENTDiscover a simpler, more cost-effective way to get the solutions your company needs to grow more flexible and efficient.

Compatible. Maybe. The Wi-Fi Alliance is to start certifying 802.11n products in March 2007, despite the fact the standard won't be completed until the following year, according to CNet.â¦

(InfoWorld) - Cisco SystemsÂ hasÂ expandedÂ aÂ range of security mechanisms for wired LANsÂ to theÂ wireless side of enterprise networks. The dominant LAN vendorÂ announceedÂ on Wednesday itÂ had upgraded its software and launched a set of guidelines for integrating wired and wireless security, called the Cisco Secure Wireless Solution. The new capabilities are available to any customer with current Cisco software, said Chris Kozup, manager of mobility solutions at Cisco. Customers can use the guidelines themselves to build a security architecture or enlist the help of Cisco's services organization or third parties. Enterprises are already able to bring wireless devices into Cisco's security system, which is built around ensuring any client is authorized and free of threats before it can hook up to the network. But bringing the same set of tools into the wireless domain can make that process easier, Kozup said. For example, if an enterprise wanted to secure wireless clients using Cisco's Network Access Control (NAC) appliance, the end user connecting via wireless would have to manually log into the NAC. Now that process can be transparent to the user, just as it is on the wired network, he said. In addition to the NAC, the architecture includes Cisco's ASA firewall, Cisco Security Agent (CSA), Cisco IPS (Intrusion Prevention System) software, Cisco Secure ACS (Access Control Server) and Cisco Secure Services Client. These long-time features of Cisco's wired security are being extended to wireless LANs as the company's latest step toward unifying wired and wireless into one network, Kozup said. The system makes the wired and wireless networks work together to bolster security. For example, if a notebook PC is connected to the LAN via a wired port, its wireless radio will be turned off automatically to prevent an attacker from using the wireless connection as a path on to the wired LAN. In addition, a Cisco wireless LAN controller, the mechanism in an appliance, router or switch that controls wireless infrastructure, can disconnect a wireless LAN client that poses a threat. The security built into all Wi-Fi products has improved in recent years and many vendors sell tools to secure wireless LANs, such as Aruba Wireless Networks Inc.'s technology that uses encrypted tunnels. Cisco's new approach may not be significantly more secure than those options, but it can simplify life for IT administrators, said Farpoint Group analyst Craig Mathias. For one thing, it's easier if security for both parts of the network uses a single directory of users, he said. Other approaches that are less expensive and more scalable can work just as well, according to Burton Group analyst Dave Passmore. "This is Cisco assuming the network perimeter needs to be protected right at the every edge, rather than a more centralized approach," Passmore said. There are no significant threats to an enterprise LAN that can't be handled from within the wired part of the network, he said.
