Vanu Bose on SDR as an answer to rural communication

Software Defined Radio is clearly good for wireless service providers because they don't have to buy a new base station each time the standard changes, or each time they want to support a new technology. So, it's cheaper for the infrastructure providers to use an SDR base station. But does this directly affect rural communication? Well, it sort of does by encouraging providers to enter into the rural market because SDR base stations are cheaper to buy, but a more direct benefit would be if Vanu can even do stuff on making cheap cellphone towers and doing some sort of a wireless mesh network to even reduce the cost of laying a fibre backbone to the cellular towers. If they do it, then that's what I would call a complete solution.
