Factors that can impact the successful transmission of a signal from its source to destination

Version 1
    Question: In wireless communications, what are the factors that can impact the successful transmission of a signal from its source to destination?

     

    Answer:

    In wireless communications, instead of moving data over physical wires, it is transmitted across the air as RF energy. There are a large number of factors that can influence what happens in this channel. Here are some simple examples:

    ■ Attenuation due to range
    ■ Attenuation due to passing through objects such as product enclosures or walls
    ■ Multi-path effects from reflections off walls, floors, or other objects
    ■ Interference from other signals
    All of these things impact the successful transmission of the signal from its source to its destination, and have it properly received.
