The free-space path loss is proportional to the square of the distance between a wireless transmitter and a receiver. The mathematical model of that can be used to determine the signal intensity of transmitted radio signal at a definite distance from the transmitting antenna. Nevertheless different environments present multipath effects and other active/ passive interferences that affect Received...
This paper discusses Monte Carlo simulations of the fading statistics that would be observed for mobile-to-mobile links in hilly and mountainous terrain. Several terrain databases are employed for the simulations. Their terrain heights are scaled so that the dependence of fading statistics on terrain standard deviation can be investigated. The simulations make use of a computer code that accounts...
We consider the problem of mitigating a highly varying wireless channel between a transmitting ground node and receivers on a small, low-altitude unmanned aerial vehicle (UAV) in a 802.11 wireless mesh network. One approach is to use multiple transmitter and receiver nodes that exploit the channel's spatial/temporal diversity and that cooperate to improve overall packet reception. We present a series...
