- | During the coverage test on the USJ CST campus, we placed the base station in a third floor classroom in one of the highest building of the campus. As mentioned before, the connected computer logs periodically timestamps and information on the received signal power. We carried the mobile device around the campus walking slowly so that the LoRa transmission and the GPS update can take place. | + | During the coverage test on the USJ [[http:// |
