Nokia RET in Dual Band Antenna|| RET Configuration in 2G BTS Site Manager

Prerequisites: Ensure that the RET controller is connected to the antenna and that both the BTS and RET controller support the feature. You must have appropriate access rights to the Site Manager for making changes. Make sure the antenna is properly installed and the RET controller is operational. Ensure the RET parameters are correctly configured for both bands (GSM900 and GSM1800, or GSM900 and DCS1800, depending on your network configuration). Steps to Configure RET in Nokia 2G BTS Site Manager (Dual-Band Antenna): 1. Access the BTS Site Manager: Log in to the Nokia 2G Site Manager (or Nokia NetAct if using centralized management) using your administrator credentials. 2. Identify the BTS and Antenna: In the Site Manager, locate the BTS for which you wish to configure the RET. Identify the dual-band antenna that is installed and linked to the BTS. The antenna should support RET functionality, meaning it will be connected to a RET controller. 3. Check RET Controller Connection: Verify the physical and logical connections between the RET controller and the antenna. Ensure the RET controller is recognized by the BTS. The controller typically communicates over RS485 or Ethernet with the BTS system. 4. Configure the RET Parameters: Navigate to the section of the Site Manager where you can configure the tilt parameters. -RET Type: Select the RET type (manual, automatic, or remote tilt). Tilt Range: Set the tilt range (e.g., 0 to 10 degrees, depending on antenna specifications). Tilt Control: Configure tilt control modes (whether manual, via RET controller, or automated based on load conditions). For a dual-band antenna ensure that the tilt angle settings are applied to both frequency bands (e.g., GSM900 and GSM1800) independently. Depending on your antenna design, the RET controller may manage the tilt angles separately for each band. 5. Adjust Tilt for Each Band (if needed): GSM900 Band: Set the tilt angle for optimal coverage and capacity in the GSM900 band. GSM1800 Band: Similarly, set the tilt for the GSM1800 band, which may require different tilt angles due to differences in propagation characteristics. 6. Monitor the RET Status: Use the Site Manager or an external monitoring system (like NetAct if available) to ensure the RET is functioning correctly. Check the RET feedback to verify that the tilt angles are within the specified range, and the controller is operating as expected. 7. Test the Configuration: After configuring the RET parameters, perform a site survey to check the coverage and performance. You may need to adjust the tilt angles based on actual coverage measurements. 8. Save and Apply Settings: Once the configuration is completed, save the changes and apply them to the system. Confirm the settings and monitor the performance to ensure optimal coverage. Troubleshooting Tips: Verify RET Controller Communication: Ensure that the RET controller is communicating with the BTS. You may need to check the connection cables or the network settings (RS485/Ethernet). Power Supply: Ensure the RET controller is properly powered. Faulty Tilt: If the antenna is not tilting as expected, verify the tilt range, communication settings, and controller response via the Site Manager logs. Software Compatibility: Ensure that the software version of the Nokia 2G BTS Site Manager is compatible with the RET functionality. Conclusion: Configuring RET on a Nokia 2G BTS Site Manager in a dual-band antenna setup involves setting the tilt range and parameters for both frequency bands, ensuring proper connectivity with the RET controller, and validating the settings through performance testing. Always follow specific antenna and controller guidelines provided by Nokia for best results.
