It wouldn’t surprise me if Dish wrote software that determined a receivers geographic location based on spot beams.
For example if you lived in the Detroit DMA, you could get a signal from the Cleveland oh, Toledo oh, Lansing Mi, Flint mi, Grand Rapids Mi, Chicago IL DMA’s only.
There would be no possible way to get a spot beam in Atlanta, Dallas, Denver or any DMA’s further away.
Using spot beam signal levels, it’s possible to write software so a receiver would only work within a specific DMA.
It would cut down on account stacking, and grey market accounts.
One of the biggest benefits would be if a customer had service in Michigan and a vacation home in Florida, they could force the customer to split the account and now Dish would have 2 customers instead of 1
