AB - Wireless Sensor Networks (WSN) are
formed by a large number of sensing nodes at the ground
level. These devices are monitoring and measuring
physical parameters from the environment. Simulation is
used to study WSN, since deploying test-beds supposes a
huge effort. However simulation results rely on physical
layer assumptions, which are not usually accurate enough
to capture the real behaviour of WSN. In this work several
measurement campaigns are performed in three different
scenarios: an open quasi-ideal area, a university yard and
a park. The main contribution of this work is that a two
slopes lognormal path-loss near ground outdoor channel
model at 868 MHz is validated, and compared to the
widely used one slope model. This model is useful
