What is the rationale behind using different slot sizes in Bluetooth? Explain clearly.
What will be an ideal response?
It is the channel quality. If channel quality is good, using multiply slots packets can provide higher throughput. On the other hand, in a noisy environment or if multiply piconets co-exist in the same area, system may have much more interference. If channel quality is not good, packets may easily get corrupted and retransmission of a large packet causes added retransmission delays. The small slots size can reduce the retransmission ratio and can get a better overall efficiency.
