Figure 88: Sensitivity analysis results <strong>for</strong> broadband soluti<strong>on</strong>s<br />
First <strong>of</strong> all, as menti<strong>on</strong>ed be<strong>for</strong>e, it can be seen that the re-use factor <strong>on</strong>ly affects LTE, since it is the<br />
<strong>on</strong>ly terrestrial opti<strong>on</strong> c<strong>on</strong>sidered <strong>for</strong> broadband. However, it has the largest impact <strong>of</strong> all within a<br />
window <strong>of</strong> high likelihood. Moreover, despite affecting <strong>on</strong>ly LTE, it impacts the competitiveness <strong>of</strong><br />
<strong>SATCOM</strong> candidates when benchmarked against their key competitor.<br />
As far as revenues are c<strong>on</strong>cerned, broadband services‘ usage or Wi-Fi Tariffs modificati<strong>on</strong>s are<br />
independent from the technology used to provide the service because <strong>of</strong> the split between costs and<br />
revenues in these two completely different models – <strong>SATCOM</strong> and terrestrial mobile technologies.<br />
Moreover, terminal prices have a str<strong>on</strong>g effect <strong>on</strong> <strong>SATCOM</strong> broadband soluti<strong>on</strong>s. This is because<br />
<strong>SATCOM</strong> broadband terminals are far more expensive than those <strong>for</strong> LTE.<br />
The c<strong>on</strong>siderati<strong>on</strong> <strong>of</strong> voice as a requirement affects <strong>SATCOM</strong> soluti<strong>on</strong>s primarily, and plays a heavy<br />
role in costs.<br />
Finally, the model is notably sensitive to communicati<strong>on</strong> tariffs, which are a main driver <strong>for</strong> the costs in<br />
<strong>SATCOM</strong> broadband representing the main source <strong>of</strong> expenses <strong>for</strong> these soluti<strong>on</strong>s.<br />
