TRANSMISSION LOSS IN RADIO PROPAGATION: II

Abstract

INVESTIGATIONS ARE CONCERNED PRIMARILY WITH THE TRANSMISSION LOSS ENCOUNTERED IN THE PROPAGATION OF RADIO ENERGY BETWEEN A TRANSMITTING AND A RECEIVING ANTENNA. Simple methods are given for determining the magnitude of this transmission loss and its variation in space and time (fading). In addition, methods are given for estimating radio noise and interference levels. When combined, these two methods make possible the estimation of the transmitter power and antenna gain required for satisfactory communication, navigation, or other specific uses of the transmissions. A survey is made of the transmission losses expected for a wide range of conditions, i.e., for distances from 10 to 10,000 statute miles; for radio frequencies from 10 kc to 100,000 mc; for vertical or horizontal polarization; for ground waves, ionospheric waves, and tropospheric waves; over sea water or over land which may be either rough or smooth; and for various geographical and climatological regions.
