SM TX Power (Lock)

[Atang_Maretele]

How can I lock my SM TX power to 30?
I do not have access to access point it is controlled by my ISP. I can only access my subscriber module. The TX power keeps reducing on high mcs values. I want it to stay at 30 when at DS MCS 9. When TX power drops link quality drops to 20% randomly. When mcs is limited to DS MCS 2 link quality stays high around 80-100%
Have already adjusted height to the max and adjusted aiming as best as I can.

Any cli commands? custom firmware?

TX power reduction as MCS rate increases is by design and cannot be forced. Please review this post for more information, specifically the section “Dynamic Tx Power - Tx Power limitation caused by quality indicators of transceiver system.”

The ePMP1000' Transmit Power

Hi vantienphap, Actually there are three mechanisms on ePMP boards which affect TX Power: 1. Regulatory,2. ATPC,3. Dynamic TX Power. ATPC works only in TDD/TDD PTP mode. 1. Regulatory - limits transmitter power in accordance with the requirements of the government agencies depending on the Country Code. It depends on the Country Code, band, mode (PMP / PTP).  Regulatory limits Tx Power both on AP and on the SM. 2. ATPC - Automatic Transmit Power Control. ATPC Settings on AP: [atpc.jpeg]  AP wi…

Isn’t there any custom firmware you can make to bypass this? Or some kind of line I can edit on my config?

My Isp is doing nothing to fix my issue with poor uplink link quality. Got no access to the access point
Limiting mcs to ds mc1 makes it better it ranges from 80-100% but retransmissions are still there but not as bad as when mcs is on ds mcs2+

I think maxing out TX power on the uplink will sort this issue out since whenever it transitions to 26 the link quality becomes 95-100%

This auto power control is not good
