Research and Markets has come out with a new study that asks some interesting questions, but doesn't offer answers unless you buy the report, apparently: One interesting question the study poses is, how can health providers, which have stringent security requirements, be major users of WLANs if security is so poor? I suppose that's because there are security solutions but they can be complicated or expensive to deploy. Another question is, why do some universities hang one AP for every 15 students and others use one for 100 students? That points to the fact that deploying WLANs is a fairly new phenomena and IT folks are likely experimenting with how many APs are necessary. Authors of the report also wonder why some startups have over 100 customers if there are too many 802.11 companies. That's a silly question as a company can have thousands of customers and still fail if the business case doesn't work out.
