Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You are designing a system for a satellite communication application. Discuss the challenges of retransmitting data and how FEC could be advantageous.

💡 Hint: Consider how signal loss and transmission time affect reliability.

Challenge 2 Hard

Given a low-latency local area network, evaluate whether ARQ or FEC would be a better choice and justify your reasoning.

💡 Hint: Think about network conditions which require quick responses for error handling.
