  • Predicting Wi-Fi performance: Can it be done?

    Whenever I plan and configure an enterprise WLAN system, I always advise that an additional 10 to 20 percent of the capital budget be reserved for expansion and filling in holes in coverage or capacity that couldn't be anticipated during the planning process.

  • No end in sight for WLAN architecture wars

    You'd have thought that, by now, we would have settled the WLAN architecture wars. You'd think one architecture or another would have been declared the winner and that we'd all be buying basically the same product from a small number of vendors -- just as is the case with Ethernet switches.

  • Goodbye, notebook; hello 'Web tablet'

    The notebook computer is doomed. OK, that's a little strong. And as one of the people who worked on the first laptop PC, the GRiD Systems Compass Computer Model 1101, there will always be a soft spot in my heart for mobile PCs. But as we move into the era of infocentricity, defined by Web 2.0 network services, the "everyone gets a CPU" model needs to be replaced by "everyone has access to an interface to the Web."

  • Are we asking too much of mobility?

    I hate to admit this, but I've been having nothing but problems with my wireless strategy of late. My goal is to be 100 percent location-independent, to be able to do anything anywhere, with whatever tools are available -- ideally, just a handheld with a browser.
