If the thoughput isn't there at 99.999%, it's not worth having.

I need to be able to get 500Mbps at about 15 miles. Is that possible with either of these? What kind of real world speeds can I expect out of these and what channel size do I need to license to get those speeds? Is there something else I should consider? What brand/model radios and dishes, what other frequencies for easier licensing, etc? It would be great to be able to get a gig that distance, but I'm trying to be realistic and get just what I really need to start with. No legal advice please, just your experience with it and any knowledge you'd be able/willing to share with the licensing of these frequencies. Thank you, Brett A Mansfield </blockquote> </blockquote> </blockquote>
