Evaluating the wireless networking options - TechUpdate - ZDNet:
"Now that wireless networking has been around for several years and is starting to mature, companies have a variety of wireless networking standards and products to choose from. There are long-distance products used to send data between buildings miles away and then there are the shorter range products that typically provide wireless networking services within an office building or a warehouse. Both of these areas have a lot of different products and standards available, and there is no way that I could discuss them all within one article.
