Abstract
The prediction of the signal path loss is an important step in the deployment of wireless networks. Despite the plethora of works on this field, just a little is addressing rural environments at 2.4 GHz. In this work, we consider empirical path loss models in wireless networks at 2.4 GHz, using off-the-shelf 802.11n. We define three scenario usually observed in rural environment: free space, raised space and built space. Afterwards, we do a measurement campaign and compare results to selected prediction models. After analysing the results, Liechty model provides a better precision than the others. This model is further improved by considering the distance between the transmitter and the first breakpoint. We obtain predictions with mean errors less than 2.4 dB which is inferior to 4.00 dB predicted using Liechty model.
