This writer seems to enjoy writing as though he's an authority when it's clear he's not: He's read all the hype about Wi-Fi but gets enough wrong that he obviously hasn't done his own research. His general point is that Canada is behind the United States in deploying hotspots. But he hasn't got very good research to back that up. His strongest piece of evidence seems to be a conversation he had recently with one computer programmer who had never heard of Wi-Fi.
He goes on to say that the market is primed to change dramatically because Canada's largest carriers said they'd create a unified standard to let customers roam between their networks. This so-called standard was developed without any of the major existing Canadian Wi-Fi operators, such as FatPort, and none of the four carriers involved had deployed hotspots when they set the roaming standard. It's also just a "standard" (how they'll handle billing, etc.), not a roaming deal. So the carriers could deploy networks and still not roam. (Meanwhile, FatPort has built hundreds of locations and secured roaming with several international networks.)
He also pointed to a recent study that said no hotspots' business model could succeed if the only revenue source was connection fees. That study is bad news for cafes in the U.S., he says, because many of them offer access for free. But the two aren't related. Free hotspot operators have a totally different business model than those that charge.
He closes by pointing out "guerilla Wi-Fi warriors" in Canada who warchalk. Warchalking is a great idea and testament to the community behind Wi-Fi, but who has actually seen a symbol? If this writer's point is that Wi-Fi hasn't taken off in Canada, then it's doubtful that people there are actually warchalking.
