Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate the SINR if the signal power is 100 mW, the noise power is 20 mW, and the interference power is 30 mW. Discuss how this SINR affects potential data rates.

💡 Hint: Use the SINR formula, and don't forget to consider how data rates may vary.

Challenge 2 Hard

Discuss how increasing thermal noise in an environment may impact the overall performance of a wireless network. Provide strategies for mitigation.

💡 Hint: Think about both hardware changes and network design strategies.
