Abstract 

The files here support the research work presented in the paper submitted for IEEE Transactions on Antennas and Propagation, "Site-specific Radio Propagation Model for 5G Macrocell Coverage at Sub-6 GHz Frequencies", which is currently under revision.This paper proposes a hybrid radio wave propagation model for 5G macrocell coverage predictions in built-up areas for sub-6 GHz frequency band. The proposed model uses various well known propagation models, such as Discrete Mixed Fourier Transform Split-Step Parabolic-Equation (DMFT-SSPE), building transmission model and ITU-R model for propagation through vegetation, to address the different propagation phenomena found for radiowave propagation in high-density urban environments. The performance of the proposed modeling approach was thoroughly validated against experimental data acquired from an extensive measurement campaign conducted in Rio de Janeiro, Brazil, in which the receiver antenna was assembled on an automotive van and it was made to travel around the city. Several drive tests were conducted, including different transmitter (TX) locations and scenarios, and at various frequencies foreseen for 5G systems, namely 750 MHz, 2.5 GHz and 3.5 GHz. In this dataset was made available, not only both simulated and measured results obtained for the various scenario taken into consideration, but also additional topographic information, namely the ground, building and vegetation elevation profiles, which can be used for further research works and benchmarking with other radiowave propagation models.

Instructions: 

The file MEASUREMENT_SCENARIOS is a MATLAB structure that contains detailed information of six different measurement scenarios, including:

  • The transmitter and receiver (RX) position (latitude and longitude) and corresponding heights
  • The ground, buildings and vegetation profile found for the radio path between the TX and RX;
  • The path vectors of the direct and diffracted multipath components (see Site-specific Radio Propagation Model for 5G Macrocell Coverage at Sub-6 GHz Frequencies paper for more detailed information about these fields);
  • And the path loss results, including the values obtained experimentally during the measurement campaign, and the values provided by the propagation model proposed in Site-specific Radio Propagation Model for 5G Macrocell Coverage at Sub-6 GHz paper.

A detailed description on the organization of the MEASUREMENT_SCENARIOS structure and its fields is available in MEASUREMENT_SCENARIOS_STRUCTURE.txt file. The measurement scenarios are divided in two different RX routes (with also different transmitter positions) and three radiowave signal frequencies (i.e. 750 MHz, 2.5 GHz and 3.5 GHz). The two receiver routes, as well as the respective TX position, can be observed in Measurement_Routes.zip file, that contains kml files that can be analyzed in Google Earth.

For the receiver route 1, the multi-band transmitter assembly was mounted on the top of the Rectory building of PUC-Rio, Brazil, located at -22.9795ยบ latitude and -43.2319ยบ longitude, and the receiver was made to travel around the Rodrigo de Freitas lagoon. The established mobile receiver drive test route had a total length of around 22.4 km and a maximum link distance, TX to RX, of 3.5424 km.

The second measurement scenario was located at Leblon beach, Brazil. The transmitter was located on the top of the hill at -22.9892ยบ latitude and -43.2290ยบ longitude, and the receiver was made to travel along the coastal road and behind the first block of buildings.

To help the visualization of the results, the user can run the MATLAB scripts provided along with this dataset:

  • View_Scenario_Profile_Sample.m allow the visualization of the ground, buildings and vegetation profile found for the radio path between the TX and RX for a measurement sample of a given measurement scenario;
  • View_Scenario_Results.m allow the visualization of both measured and simulated loss results for a specific measurement scenario.
