CHANGE POWER CONTROL

Hi community,

I have a PMP450 SM Product and I am creating a template to change the SNMP & POWER CONTROL

the SNMP part its working properly but the parameter "Max Tx Power" not change to 27.

Someone can help me?

I need to change the Max Tx Power to 27db and change the state to "enable".

{
  "userParameters": {
    "snmpConfig": {
      "commStringRW": "XXXXX"
    },
    "radioConfig": {
      "transmitterOP": 27
    }
  }
}

Hi David,

Check the SM's web GUI's Configuration -> Radio page for if 27 is beyond the Max Tx Power limit.  It should say what the valid range is there.  This limit is based on regional settings.  More details on this in available in the 450 Platform User Guide on the support page.

The range its between -30 and +27, when I run the script, the parameter Max tx power not change.

I try with 21,23,27 but nothing works. Only the part of SNMP. 

I dont need to change it on the antenna menu, i need to make it work on the script because I tried to changed a few times but doesnt work.

Hi David,

I have forwarded your post to some of our PMP engineers to take a closer look.

David,


Under whisp SM Config there is the OID "maxTxPowerEnable" (.1.3.6.1.4.1.161.19.3.2.1.160.0) that MIB description says:
Enable Max Tx Power configuration.
This is used with OID maxTxPower to set the max transmit power.
This might be required in certain regions and frequency bands.
See User Guide for more information.
Enabling this will not allow a radio to transmit above its EIRP limit.
The AP's Transmit Power Control may still adjust the Tx power down.
SM only.

So "maxTxPower" (.1.3.6.1.4.1.161.19.3.2.1.161.0) SM's OID description reads:
This OID is controlled by OID maxTxPowerEnable.
This might be required in certain regions and frequency bands.
See user guide for more information.
Setting this will not allow a radio to transmit above its EIRP limit.
The AP's Transmit Power Control may still adjust the Tx power down.
SM only.

Does it work when you manually change it in SNMP? That might be good to check.

Then the only issue left would be configuration file. What I suggest is making the change manually and then downloading your Configuration File (Configuration -> Unit Settings -> Download Configuration File). So I did this and see this as part of the config file:

...

"smRadioConfig": {
"powerUpMode": 0,
"frequencyScanList": [
5760000,
5770000,
5780000
],
"maxTxPowerEnable": 1,
"apSelection": 0,
"maxTxPower": 24,
"bandwidthScanList": [
100,
200,
400
],

...


Does any of that help?

On a related question, why are you capping your SM's Transmit Power?
