Further, a separate public safety network does not more new cell sites beyond the base required for public safety have similar economies of scope, such as sharing an IP core LMR networks; the costs of backhaul from the cell sites; and the network with other uses. costs for a core network. This lack of scope is compounded if the public safety entity In this analysis, we considered the complexity and scope of is operating on an LTE network that utilizes spectrum in a band constructing a nationwide stand-alone public safety network, class assigned exclusively for the public safety community. in which 80% of the 44,800 sites would be new builds.

In that situation, there would be no commercial service development costs and time to market, wireless carriers and provider in LTE Band Class 14 in the 700 MHz band.

In suburban and rural America, ongoing costs at either two or 2.5 times the total capex amount.18 however, new site acquisition, zoning and construction will in general be substantively higher. Our analysis indicates that a stand-alone public safety network would be substantially more expensive than a network constructed under the incentive-based partnership approach. Conservatively, the stand-alone network would require at least 2.5 times more capex, excluding deployable equipment, and proportionally even more in ongoing costs.14 The total present value of the capital expenses and ongoing costs for the stand- alone network over the next 10 years is approximately $34.4 billion, taking into consideration that capex is $15.7 billion and ongoing costs are 1.5 times the total capex amount.15 This anal- ysis is consistent with both the Verizon study for the Southern
