Consider a set of wireless devices using different modulation techniques. If Device A uses BPSK and Device B uses QPSK, explain how Device B achieves higher data rates and what would be the impact of noise on their transmissions.
💡 Hint: Think about the trade-offs between data rates and noise resilience.
An 802.11n device uses 64-QAM under good signal conditions. If it moves into an area with poor quality signals, how might it adapt its modulation and coding? Explain the process.
💡 Hint: Consider how dynamic conditions of the signal impact the device's strategies.
