At least one reader was sufficiently upset by the article to post a comment in the WirelessNetDesignline forum taking issue with the authors.
As you may have noticed, the site's been pretty intensely focused recently on the Bluetooth SIG's decision to use Wi-Fi as an interim technology for high-speed Bluetooth.
First, we had the announcement of High-Speed Bluetooth over Wi-Fi. That was more than a month ago and it did not draw much attention initially. But it apparently did not go down well in the WiMedia Alliance camp, which, for the last year or so, thought it had won the competition to be Bluetooth's faster brother.
WiMedia was put on the Bluetooth back burner for good reason: The higher frequency chips that would operate in the 6 GHz range while Bluetooth operated in the ISM band just weren't ready and don't appear likely to be anytime soon.
It didn't take long to see WiMedia's reaction to the Wi-Fi incursion transformed into a concern.
In last week's featured article, the authors from Staccato (a WiMedia Alliance member) contended that under certain circumstances Wi-Fi would interfere with WiMAX and with other cellular technologies that operate in adjacent bands.
At least one reader was sufficiently upset by the article to post a comment in the WirelessNetDesignline forum taking issue with some of the authors' assumptions as well as the test procedures the authors used.

Today I posted an article on Bluetooth/Wi-Fi interference. In some ways this is a tougher problem than Wi-Fi/WiMAX interference and the article shows how clever design can address interference problems.
There's more to come. Look for another featurethis one from the Bluetooth SIGthat will explain the whys and wherefores of the Wi-Fi choice in a broad context.
So is as usually the case, we have to sort out whether the WiMedia Alliance is practicing the marketing technique that has come to be known as FUD (introducing Fear, Uncertainty and Doubt into the market so as to buy time while it gets its higher frequency chips ready).
For my part, I'm beginning to wonder why the authors from Staccato chose to use WiMAX as its target technology for Wi-Fi interference. Here is another standard that is having trouble gaining traction. Why not use a mature technology that is already in the market instead?
