Can't wait, this should be a great technology.
Think of an 802.22 device (transmit / receive signals) to a ethernet connection to your 802.11 router. No modem needed. and you could take it with you in your car/truck and have a mobile network. Or use Skype device(like a cell/smartphone) that uses 802.22 for VoIP, no wonder Microsoft purchased Skype, they'll be a phone company! wow! 8)
A tablet with 802.11/802.22/g3 networking built-in, be connected at all times. no more cell towers every 5-10 mile to maintain signal. 802.22 is good for 60 miles. oh ya, think of one for all of northwest whatcom county.
