Here is an interesting fact: if you take the square footage of the United States, from the US Geological website, it breaks down how many square feet we have in our Metro versus Rural environments. By using those figures, and mathematically accounting for your fixed tower coverage at 100% with LTE (Long term Evolution), then multiplying it by an average of $250K per site, you can figure out just how much it will cost (roughly) to build just the radio access (RAN) portion of FirstNet. I have listed that calculation broken down to the State level. This gives you an idea of what it will cost and how many towers will be needed per each State (no territories at this time). The RAN is just the tower portion, and does not include fiber access, microwave (although it could on this piece),Data Centers, Control Centers, mobility or handsets....not even long-term maintenance.
