               measurement, we want to make sure that the antenna pattern at the base station will not
               get distorted, and the drive test needs to be kept at a constant speed to obtain a local
               mean later by averaging every 20 to 40 "A length of data along the test run.
                  The following process is used to derive the building loss curve:
                    1. Manage the measured database on GPS and ETAK data
                    2. Filter the umeliable data
