Description

Site deployment

After the area for deploying a site is specified, the U-Net quickly creates the site on the map by using the base station (BS) template. By performing point analysis, the U-Net can analyze the ground altitude and clutter height along the profile of the propagation path to adjust site deployment.

Model calibration

Users can manually or automatically enable the U-Net to calibrate the propagation model based on the DT data and the CW data. The U-Net displays the model on the GIS to analyze the error in the model-based calculation.

Network planning

The U-Net helps users to plan configuration parameters of the LTE network, such as parameters related to the neighboring cells, PCIs, frequencies, PRACHs, and TAs.

RF planning

The U-Net helps users to plan configuration parameters of antennas to ensure optimal network coverage and capacity.

Coverage prediction

The U-Net starts the coverage prediction after importing the map and configuring network data, service model, and propagation model. By analyzing network coverage, it locates the area that has poor coverage.

Capacity simulation

After the traffic parameters are configured and the traffic map is set according to the planning, the U-Net performs the simulation calculation based on the traffic map. In capacity simulation, the U-Net can also analyze KPIs such as the success rate of subscriber access and the call drop rate. In addition, it analyzes the coverage of common channels and traffic channels based on the specific network load provided in the simulation calculation results.

Interaction with the CME

Issue V1.0(2013-04-24)

Users can obtain configuration parameters from the CME and then import them to the U-Net for coverage prediction and analysis. The analysis results provided by the U-Net can be imported to the CME and then be delivered to the network.
