LTE Urban

Perform network planning for an urban scenario using long-term evolution (LTE).

Sites and Antennas

The model has six sites where each site consists of three antennas placed at a height of 35 m. The sites are placed at different locations throughout the urban area for the best coverage. Each antenna of the site has a directional radiation pattern intended to cover a sector of 120 degrees. The different frequencies used for propagation are around 2.6 GHz, and the transmitter power per antenna is 46 dBm.

Air Interface

A long term evolution (LTE) air interface is used in this model. Orthogonal frequency division multiple access (OFDM/SOFDMA) is selected for multiple access. The duplex separation between uplink and downlink is 190 MHz and is achieved by using frequency division duplex (FDD).
Tip: Click Project > Edit Project Parameter and click the Air Interface tab.

Computational Method

For an urban environment, the dominant path model (DPM) is well-suited. DPM focuses on the most relevant path, which leads to shorter computation times compared to 3D ray tracing.

Tip: Click Project > Edit Project Parameter and click the Computation tab to change the model.


Propagation results show at every location the power received from each transmitting antenna. Figure 1 shows the received power from Site 1 Antenna 1 at a height of 1.5 m

The type of network simulation is a Static Simulation (homogeneous traffic per cell). The network simulation calculates the following results for both downlink and uplink:
  • cell area
  • site area
  • best server
  • maximum data rate
  • minimum required transmitter power
  • maximum received power
  • SNIR
  • deception probability
  • number of streams
  • throughput for all modulation and coding schemes
Figure 2 shows the cell area network planning results.
