1.	The transmission of multiple signals in a common frequency without interference is called _______(a) Time division multiplexing(b) Frequency division multiplexing(c) Code division multiplexing(d) Spatial multiplexingI got this question in final exam.The query is from Frequency Division Multiplexing in section Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics
Answer» RIGHT choice is (d) Spatial multiplexing Best explanation: Spatial multiplexing is the term used to describe the transmission of multiple WIRELESS signals on a common frequency in such a way that they do not interfere with one another. One way of doing this is to use low-POWER transmissions so that the signals do not interfere with one another. When very low power is used, the signals do not travel very far. The transmission distance is a FUNCTION of the power level, frequency, and ANTENNA height.
