Based on the measurement results, a new path loss model is proposed. It is shown that this model provides a more realistic prediction of the path loss for MANET systems in the VHF and UHF band than the widely used Okumura Hata model. This path loss model was developed by 3GPP and its detailed description can be found in [1]. The model is applicable for link and system level simulations in the frequency band 0.5–100 GHz, for bandwidths up to 10% of the center frequency but not larger than 2 GHz, and for urban macro cell (UMa), urban micro cell street canyon (UMi-Street canyon), rural macro cell (RMa), and indoor office.

(For PCS, this means 1m-10m track) lThe models that predict the mean signal strength for an arbitrary-receiver transmitter (T-R) separation distance are called large-scale propagation models models based on such parameter extraction are the Okumura-Hata models [2], the COST 231 path loss models [3], and many more, see, e.g., [4], [5], and references therein. Most path loss models assume a power-law dependence on distance on a logarithmic scale 10 log 10 (d) + , which is a straight line on a ”power in dB” - vs - log 10 (d)-plot. In this paper, measurements of the path loss using car-mounted receiver and transmitter antennas are presented. Based on the measurement results, a new path loss model is proposed.
