Homework Help: The Electromagnetic Spectrum

  1. Mar 11, 2006 #1
    3. Identify the Electromagnetic Spectrum range utilised in modern communication technologies. You must include secondary data in tabular and/or graphical form, interpret it into words and analyse.

    What kind of tables or graphs would I want to show here?

    look up FCC (Federal Communication Commission).
    Some bands are reserved for future expansion, some for emergency,
    some for commercial and licenced, some regulated (ham), some public.

    How much "reserved" is left for when new technology becomes available?
