Pros: Ubiquity, Low-cost access, Faster Internet, Easy access Cons: Cumbersome technology, Lots of maintenance, No major development since October 2018
Pros: Compatibility, Reliability (higher altitude and a lower number of satellites), Lower cost of satellites Cons: The technology is not as reliable as it may be in the future, given that it is a satellite-based network
