Rate algorithm performance

Hi everyone, somebody has experiencie working with rate algorithm (Optimistic Algorithm, Conservative Algorithm, EWMA Algorithm) can tell me when you uses and for what.

Thanks.

A simplification is....

Optimistic means it tries the best speed, but more sensitive to noise problems.
Conservative is less prone to noise, but slower.

Channel Spectrum Width: Semakin kecil semakin bagus (5Mhz)
Output Power: Power besar, belum tentu data lancar. Pertimbangkan antara jarak dan stablitas link (25db untuk 6km)
Distance: Point ini berpegaruh besar dalam QOS link
