220-801 · Question #794
Which of the following Internet technologies has the slowest potential upload speed due to inherent latency issues?
The correct answer is C. Satellite. Satellite Internet has the slowest effective upload speed among the options listed because signals must travel approximately 35,000 km to a geostationary satellite and back, introducing inherent high latency.

Why each option
Satellite Internet has the slowest effective upload speed among the options listed because signals must travel approximately 35,000 km to a geostationary satellite and back, introducing inherent high latency.
3G cellular has higher latency than 4G and fiber but does not suffer from the extreme propagation delay inherent to geostationary satellite systems.
4G LTE offers relatively low latency (typically 30-50 ms) and higher upload speeds than satellite, making it faster for uploads.
Geostationary satellite Internet requires signals to travel roughly 35,786 km to the satellite and back, creating a one-way propagation delay of approximately 250-280 ms and a round-trip latency of 500-600 ms or more. This physics-bound latency severely limits throughput efficiency for upload sessions and cannot be eliminated through hardware improvements, making it the slowest in practice among the listed technologies.
Fiber optic Internet has extremely low latency and very high upload speeds, making it the fastest option listed.
