Are these links RF or Land Based? Are there any examples of fast (> 1 megabit) RF Mesh Networks with greater than 5 hops in the RF Mesh and, say, around 20 active talkers at once behind the last hops of the Mesh?

I'm happy to get 100 kbits/talker in that scenario with todays FHSS technology, 500 meters/hop, 1 watt power, 200 kHz channel width and 20 MHz of spectrum in the ISM band.

Of course, the advantage of Mesh Networks is they require little in the way of infrastructure, and scale up into the millions of nodes, with 50 million active node networks practical. But high data rates are not one of the properties of such networks.

Well, it's RF between the cell phone and the cell tower. Between the switches, it's most likely land based circuits, but really, they could be anything.
