Path loss variation due to vegetation movement

With the development of UMTS technology the cost of CDMA systems is likely to fall. This technology will become a candidate for providing fixed access as well as mobile. UMTS will work in the 2 GHz band so it would make good sense to use some of the technology for fixed access in remote rural areas. Rural areas in the UK tend to have a significant number of trees which may affect propagation between base stations and customer terminals. This paper describes measurements made with a view to characterising the influence of trees on path losses when the foliage moves in the wind.
