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 multiplexing |
|
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. |
