Abstract

This paper describes the result of measurements of the correction factor for buildings around a mobile station on UHF land mobile propagation characteristics. In order to express buildings around a mobile station quantitatively, four parameters are proposed: area factor of occupied buildings $(\\alpha )$ , extended-area factor of occupied buildings $(alph\\acute{a} )$ , buildings volume over a sampled area $(\\beta )$ and buildings volume over an extended-area $(bet\\acute{a} )$ . The examination was carried out for each parameter in the 400 MHz and the 800 MHz bands. Consequently, it was clear that α was a suitable parameter for buildings around a mobile station, considering the balance of prediction accuracy and the efforts required to calculate a parameter.
