Hi, pix. I cannot still answer that question.
I think it has a threshold. When a MS stand near by BTS, MS will transmit a limited power, and the maximum power in this case is 33 dBm. Because if you transmit more than 33 dBm, BTS will receive a signal with higher BER, it isnot realibility. But i cannot explain it convincingly because i havenot any information about it and may be, it has a figure obout BER vs MS Tx Power.
Please help me.
