What's the deal with 900Mhz radios, like the ones Ubiquity makes... is 900Mhz licensed or unlicensed in US and Canada?

What's the benefit of 900Mhz - does it penetrate walls and trees better than 2.4 and 5.8? I believe it does. If so, when what's the trade-off? must be a good reason why all consumer-grade WIFI gear uses 2.4, with the odd 5.8 mixed in.

Antonio has suggested his idea of using higher cost/more versatile equipment like that from Ubiquity as a "power node" that forms the backbone of the network. If 900MHz can penetrate many storeys of a concrete building, and do so with little or no interference, then it would be a great thing.

In the US, it depends on what part of the 900mhz range your using on whether it is a licensed transmission or not.

If you use the 902–928 MHz (centre frequency 915 MHz), this is unlicensed and is called the ISM Band. (Such as cordless phones, or some wifi gear)

However, other 900mhz frequencies other than the ones I listed above are licensed. (Such as Cell phones)

This should help:

Unfortunately many things really like this band also, baby monitors, cordless phones, pagers, and especially Ham Operators and SCADA systems. Those last two are allowed about 5 times more power than you or I. However, properly engineered, it's not a bad place to be for certain applications.
