Arduino Project to Product-Part 5-Testing LoRa Range

2019-07-22 | By Maker.io Staff

In this video, Shawn Hymel continues the tutorial on operating voltage optimization by examining the effects of 1.9V and 5V supplies on the RFM95’s RF output power. He discusses power, dBm, antenna length and antenna radiation in detail as well as the formulas used to determine theoretical values. Using real-world tests to determine the actual effect on receiving range, Shawn employs RSSI (Received Signal Strength Indication) to quantify the empirical line-of-sight testing.
