Abstract

Multi-frequency CW measurements were made in residential environments over the frequency range of 455 MHz to 4.2 GHz, for personal communications. The seasonal effects of vegetation were also estimated. The base station antenna height was 8.2 m (27 ft). The results show an additional transmission loss of about 15 dB for 300 meter (1000-foot) paths and similar antennas at 1.9 GHz, compared to 815 MHz. The standard deviation of the data and the distance exponent of the median level also increase by approximately 10 percent. A link budget analysis examines the implications for providing personal communications services
