Does WiFi work?

The ugly thing here is that in the short term, these [WiFi] deployments will work,
just like shared-media Ethernet networks worked well in the 1980's. But at
some point, user density gets so high that the protocols break down. They
spend more time recovering from errors than they do transmitting good data.
For Ethernet, switches saved the day. But for wireless, that won't work.

I call cheap WiFi the "pizza lady" model. In the grocery store, a little old lady hands out little pieces of pizza, saying, "Try this, it's good!"

WiFi is way of getting dial up users to move at low cost to broadband. What I tell communities is that WiFi will sell fiber. As more and more users crowd on to WiFi, the bandwidth degrades, but by then, people are hooked on broadband, and can't live without the pizza, er, bandwidth.

So they are more willing to support community fiber projects.

WiFi is not THE solution. It is A solution. Fiber is also a solution. There is no one transport mechanism that will satisfy everything we want to do.
