SetTransmitPower() sets the modules TX power Transceiver.SetXXX() - controls a parameter defined during communication between E32 modules Transceiver.init() starts the communication between E32 modules (TX and RX) The general process for using the EBYTE library is as follows:ĮSerial.begin(9600) - starts UART comm.

In the next section, wiring the LoRa modules to Arduino is outlined, along with a list of parts used in this tutorial series. We will likely see variations in range based on directionality and building heights - so the exploration of the true urban range of the LoRa wide area network will be tested and quantified. The range of the LoRa modules will also be tested in New York City, where the path loss will be even more complex. RF link budget analysis in urban propagation microcell environment for mobile radio communication systems link planning by Ardavan Rahimian and Farhad Mehran Path loss measurements for a non-line-of-sight mobile-to-mobile environment by J. The LoRa Protocol Technical Brief by John Sonnenberg at Raveon Technologies Corp The Link Budget and Fade Margin by Campbell Scientific, Inc. More in-depth examples of fade margins and path loss and calculations that can improve the approximations of radio communication efficiency can be found in the literature citations below:Įmpirical formula for propagation loss in land mobile radio services by M. It is also entirely possible that our path loss method is incorrect and does not account for some of the conditions of the manufacturer’s testing.

The value of the fade margin in this case is likely around 71 dBm, which is fairly high.
