Starting from the general requirements imposed on the transmitting medium, this paper discusses the engineering of a radio system for television purposes and describes the radio facilities actually

We present a novel technique for radio transmitter identification based on frequency domain characteristics.

Diffusion theory is found to provide a simple yet accurate expression for the average received radio power loss indoors in non-Line-of-Sight. Effective specific absorption is the sole parameter.

Many digital radio-relay routes use radio-frequency channel arrangements originally designed to accommodate analog radio-relay systems.

When radio-relay and communication satellite systems share frequency bands, as they do at 4 and 6 GHz, it is necessary to impose restrictions on both systems so that interference is not excessive.
