Huawei RET Configration process

Huawei RET Configuration Process
Understanding RET

Before diving into the configuration process, it's essential to grasp what RET is. RET stands for Remote Electrical Tilt. It's a technology that allows for dynamic adjustment of antenna tilt without physically changing the antenna's position. This is crucial for optimizing network coverage and capacity.

General Configuration Steps

While specific commands and procedures might vary based on Huawei's exact model and software version, here's a general outline of the RET configuration process:

Device Discovery:

Use the SCN ALD command to scan the network for RET devices. This will provide information like device type, vendor code, and serial number.
RET Modification:

Employ the MOD RET command to modify RET parameters based on the information gathered from the SCN ALD command. This includes:
Device type
Vendor code
Serial number
Ensuring the configuration status is "unconfigure"
Verifying the power switch at the control port is on using DSP REPORT
Adjusting antenna scenario based on hardware installation
RET Port Configuration:

Use the MOD RET PORT command to configure RET ports. Typically, this involves turning on the ports. Example:
MOD RET PORT:CN=0,SRN=60,SN=0,PWRSWITCH=ON;
MOD RET PORT:CN=0,SRN=61,SN=0,PWRSWITCH=ON;
RET Addition:

Once the RET device is discovered and modified, use the ADD RET command to add it to the configuration.
Calibration:

After the RET antenna is installed, calibration is mandatory. This ensures accurate downtilt and optimal network performance.
Additional Considerations

TMA Configuration:
If applicable, configure the Tower Mounted Amplifier (TMA) to work with the RET. This involves setting TMA attributes like working mode and gain.
Antenna Scenario:
Carefully adjust the antenna scenario based on the hardware installation to achieve the desired coverage pattern.
Verification:
Thoroughly verify the RET configuration and performance using relevant commands and tools.
Important Notes:

Always refer to the specific Huawei documentation for your equipment model and software version.
Backup your configuration before making changes.
Follow safety guidelines when working on antenna systems.
