👉 In telecommunications, "gain call" refers to a type of transmission error that occurs when a signal is transmitted at an angle or phase difference from its intended direction. This can happen because of atmospheric interference, reflection, reflection off obstacles like trees or buildings, or even due to the physical characteristics of the medium used for transmitting the signal. When a signal is "gained" by using a gain call technique, it means that the transmitted signal is shifted towards the receiver's intended direction and thus reduces the
