Appendix C: Practical measurement techniques – The practical techniques for measuring mobile coverage and mobile signal quality are diverse in their use and handling, but they often measure the same test parameters. The measurements have to be precise enough to evaluate the potential reduction in quality of service caused by the degraded network performance. Test parameters generally include (but are not limited to): Download speed (from the measurement server to the user) Upload speed (from the user to the measurement server) Ping (latency) Packet loss Signal strength Connection transparency Besides the theoretical modelling of mobile coverage, all measurement techniques can also be done by not-specialized teams, a panel of end-users or by crowdsourcing via a provided measurement app, although the measurement is sometimes carried out by specialists with testing equipment. Theoretical modelling Theoretical modelling is based on mathematical and statistical calculations. To simulate coverage extents the following parameters could be needed: Digital Elevation Models (DEM) or Digital Surface Models (DSM) Location of base stations Antenna information (e.g. HCM-Agreement on data exchange; Source: Attenuation of signals for indoor coverage; Maps used in the calculations including the population maps; Propagation models; Indication of measurements done to calibrate the propagation models, if applicable; Sensitivity per service; SNIR per service; Coding rate per service; Modulation per service; Typical antennas used, including the radiation patterns; Link budgets. The attenuation for indoor coverage may differ between older buildings, energy efficient buildings and moving vehicles, like cars or trains.
