    Different devices => different freq. to operate (Probably this is wrong already) Bandwidth = freq??

    Bandwidth of a device is the 'range' of frequencies for which the device will generate a 'desirable' output. Designing a device has Bandwidth specifications, depending on which the components used for designing will differ OR the dimensions of a devise will change. example : Designing a filter for different bandwidth will have resistors and capacitors of different values. Designing a micro-strip antenna of different center frequency and bandwidth will have different length , width, height of substrate, and slit dimensions,if any.

    yes, i addressed her 'Bandwidth = freq??' issue.

    does the original question demand differences between various spectrums like radio, optical, UV , X-rays, Gamma-rays....... coz allocation was only discussed.

    The question is ''what are the differences between different spectrum (telecom)?'' The teacher answered it once, but very quickly and I couldn't catch his words..
