Some Office 2007 beta testers can test drive a forthcoming service from Microsoft that helps users manage wireless connections when they are using Wi-Fi hot spots.According to the Techlog.org blog, Microsoft this week allowed select beta testers of Office 2007 to preview a forthcoming service called Windows Live Wi-Fi Center. Office 2007, in beta 2 now, is expected to be available to business users by the end of the year, and consumers in early 2007.Microsoft confirmed through its public relations firm Wednesday that Windows Live Wi-Fi Center is now available in a "limited, managed beta." The service will offer users a simple and secure way to locate and connect to Wi-Fi "hot spots," or networks, globally, Microsoft said. It will also provide users with encrypted connections for secure and nonsecure wireless network connectivity. Key features of Windows Live Wi-Fi Center include a network locator, which allows users to search for free and fee-based wireless networks all over the world, and network management, which lets users see what networks are around them and get information about the networks, including the network address, description, available amenities, service providers and signal strength. Customers of the service also can label networks as "favorites" for future connections, track connection history and manage network preferences. Windows Live Wi-Fi Center also will provide built-in security, including a VPN, which lets users secure a connection on unsecured wireless networks, Microsoft said. Microsoft also plans to launch the Windows Live Wi-Fi Hot Spot Locator website at hotspot.live.com. The site helps people find wireless hot spots and is accessible through any PC.Since Microsoft launched its Windows Live services in November, it has amassed a portfolio of Web-based services, some of which were previously part of its MSN portfolio, and some of which are new. More information about Windows Live can be found here.Windows Live got a lot of attention when it was first launched, but critics have become increasingly skeptical of whether Microsoft can use the services to drive advertising revenue and keep up with competitors Google and Yahoo.They also are waiting to see when sales made through the company\u2019s adCenter paid-search advertising platform\u2014which the Live services are supposed to support\u2014will pick up steam. Microsoft launched adCenter in the United States\u00a0in May, but it has yet to contribute to the overall financial health of the company\u2019s MSN division, where the platform resides.-Elizabeth Montalbano, IDG News Service (San Francisco Bureau)This article is posted on our Microsoft Informer page.\u00a0For more news on the Redmond, Wash.-based powerhouse, keep checking in.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
