Comparison among the analyzed solutions for rural coverage.

Solution (Section)	Advantages	Disadvantages
UAVs [Section 3.1]	Easily deployable and portable. Reliable infrastructure to enhance coverage. New security standards by new routing protocols. Compatible with others as terrestrial and aerial network’s platforms.	Static-channel-modeling intermittent connectivity. Energy constraints and limited effective payload. Uncertainty on legislation. Inefficient obstacle awareness rollout.
HAPs [Section 3.2]	Commit to cover immensely inaccessible areas. Allows adaptable resource allocation. Low roll-out costs. Guarantee connectivity by a single platform. Agile deployment. Payload upgrading.	Few protocol standardization. Unfit design of traffic aggregation. Poor raters of interference mitigation in shared spectrum.
LEOs [Section 3.2]	Enable higher QoS than terrestrial. Reach a latency issue standard. Add significant bit rate capacity. Provide high capacity backhaul.	Insufficient coverage time assessment. Higher cost of deployment and maintenance. Most affected by fading effects. Unreliable communication at low elevation angles.
