Dear E experts, what are the steps in a LTE cell to change its range from 10 to 35 km. As far as I know I should change cellrange and rootsequence accordingly. But is there something else to change.
Thanks

Apart from that you also need to change "Preamble Format" to 2
You're on the right track! Modifying the cell range and root sequence are indeed the main steps to increase the coverage area of an LTE cell from 10 km to 35 km. However, there are additional considerations to ensure successful implementation:
- Transmission Power: Increasing the cell range requires boosting the transmission power of the cell tower. This has limitations due to regulations on radio frequency emissions. You'll need to verify the maximum allowed power level for your region.
- Tilt and Antenna Configuration: The tilt angle of the antenna and its configuration (directional or omnidirectional) affect how the signal propagates. To cover a wider range at 35 km, adjustments to these might be necessary.
- Impact on Other Cells: Expanding the range of one cell can interfere with neighboring cells. You'll likely need to optimize the parameters of surrounding cells to avoid signal overlap and dropped connections.
- Backhaul Capacity: The increased range translates to more devices connecting to the cell. Ensure your backhaul connection (the link between the cell tower and the core network) has sufficient capacity to handle the additional traffic.
Here's a possible approach:
- Check Regulations: Research the maximum permitted transmission power for LTE in your area.
- Cell Configuration Review: Analyze the current tilt angle and antenna configuration of the cell.
- Simulate Changes: Use radio propagation software to simulate the impact of increased range on neighboring cells.
- Backhaul Capacity Assessment: Evaluate the capacity of your backhaul connection and consider potential upgrades if needed.
- Parameter adjustments: Carefully modify the cell range, root sequence, transmission power, tilt angle, and potentially antenna configuration based on simulations and regulatory limitations.
- Monitor and Fine-tune: After implementing the changes, monitor signal strength, call quality, and data throughput. Fine-tune parameters as needed to optimize performance.
