Novel model for propagation loss prediction in tunnels
Radio signal propagation in a tunnel exhibits distinct near and far regions with quite different propagation characteristics. This paper proposes a model that can distinguish these propagation regions and predict their respective propagation losses in...

description |
Radio signal propagation in a tunnel exhibits distinct
near and far regions with quite different propagation characteristics.
This paper proposes a model that can distinguish these propagation
regions and predict their respective propagation losses in
the tunnel. The model relies on a break point to separate the propagation
regions and a hybrid technique to calculate the propagation
losses. The location of the break point is determined with the
solution of a novel tunnel-propagation equation for the first time.
The solution shows that the location of the break point depends
strongly upon frequency, antenna position, and tunnel transversal
dimensions. The model is compared with data measured in various
tunnels at different frequencies (900 MHz, 1.8 GHz, and 2.448
GHz). The results show reasonable agreement between predictions
and measurements. |
