Wimax Bpenum -

If your live NUM exceeds these values, immediately reduce the UL_* allocations or increase the frame duration (e.g., 5ms to 10ms) to allow more grants per frame.

Increasing the number of multiplexed users (NUM) without adjusting the BPeNUM partition leads to thrashing . Each user receives a smaller grant, which increases overhead (MAP messages). At a critical point, overhead consumes >50% of the airlink, and effective throughput collapses. wimax bpenum
