LoRa Radio Link Range Test

This video will show the results of my LoRa radio link range test. Tips on how to increase your LoRa transmission range will be covered. E32-915T30D Lora module, user manual and config software available from Ebyte: www.cdebyte.com The RF output power specification that we see in the data sheet of the 915T30D is the "Channel Power" measurement with the units dbm/Hz or watts/Hz. This power spectral density is the maximum allowed power we can apply to the antenna. ( Max peak conducted output power). The 915T30D has a RF output level of 30dbm/500KHz or 1 Watt/500KHz. This is the Power Spectral Density which is a calculated value not a measured value. It is the power present in a signal as a function of frequency. It is the integration of the instantaneous power across the wideband output signal which is calculated by the spectrum analyzer. The RF power output of a CW narrowband signal can be measured with a wattmeter. The RF output power of a wideband spread spectrum signal is the power density or channel power which is measured across the frequency range of the signal using a spectrum analyzer.    • How to Make Channel Power Measurements
