Slot Aloha Limit Throughput

EPC Gen2 builds on slot Aloha, which has a crucial nature:
Max Throughput = 1 / e = 36.79%

Simulator generates the result around 34% (above 1000 tags)

Now the concentrates are on:
Reduce Q parameter update frequency: as far as we know, Q parameter decreases as the detection process going. Fluctuating Q causes redundant data in transmission.

Find an out of box method to break the slot Aloha throughput limit.
