MAXAR HIGH-RESOLUTION, HIGH-ACCURACY 3D GEODATA OVER AN EXAMPLE CITY This mobile operator contracted Netscout™, an independent company specializing in drive testing measurement collection and propagation model tuning, to conduct such an exercise on several bands (ranging from low frequencies to mid-band frequencies) and in different environments (urban and suburban) over a very large area where the customer already had legacy 10 m 2D geodata and where it recently acquired Maxar's 1 m 3D geodata. Aer completing the drive testing campaign and utilizing the collected measurements, Netscout™ tuned the propagation model separately for each geodata dataset. The model tuning exercise was used to achieve a mean error in radio planning simulations close to 0 decibels (dB). This exercise brought each tuned model and geodata dataset as close as possible to an ideal situation. In these ideal situations, the remaining metric to be assessed was the standard deviation error, which represents the amplitude or variation in the errors between the simulated results and the live collected measurements. Typically, the standard deviation error ranges from 5 to 8 dB—the smaller the value, the closer to reality the simulated results will be. FIGURE 2. MAXAR 1 M 3D GEODATA COMPARED TO TRADITIONAL 10 M 2D GEODATA Maxar creates the most accurate 3D digital twins of Earth. Maxar 1 m 3D geodata (le) and traditional 10 m 2D geodata (right) over an example city. In the case of traditional 10 m 2D geodata, radio planning tools would have to rely mainly on clutter classification to determine the signal propagation loss. The impact of accurate 3D geodata based on live collected measurements A Maxar customer (a Tier-1 mobile operator in North America) has assessed the impact of Maxar's high-resolution, high- accuracy 3D geodata on its 5G deployment, compared to the traditional 2D lower-resolution geodata maps the customer has used for its legacy 2G/3G/4G deployments. Figures 1 and 2 show Maxar 3D geodata over an example city and a comparison with traditional 2D geodata.
