said by GNca George:said by Martian3:Bell's portable and rural internet are both WiMAX-based services. Portable just has an indoor WiMAX modem, while rural uses an outdoor directional antenna for those with a weaker signal.
WiMAX is being developed jointly by Rogers and Bell through Inukshuk. I know Xplornet is another WiMAX provider, but I don't know much about their service. Their reviews here on DSLR don't look good.
Innukshuk/Bell/Rogers isn't real WiMax, it was deployed before WiMax became a standard. WiMax-like is a better description.
Xplornet is Motorola Canopy wireless, non-WiMax. Most of their service in these parts is delivered on 900 Mhz and I haven't met a really happy Xplornet customer in a long time. I get at least a couple calls a week from unhappy Xplorenet users looking for better service. Some areas are better than others of course...

Agreed on the not so happy Xplornet comments 
Xplornet does have some WiMax deployments in our area and down through Kingston too. It's not widespread with them I don't think but they are using it in certain areas....
