I would say that the line from Edgar Allan Poe's The Raven that provides information about the setting of the poem is:
<span>As of some one gently rapping, rapping at my chamber door.
</span>
Based on this line, we see that the setting is in a chamber.
I am a bit sure it is communicate
ELECTRICITY then SATELLITES and the television ANTENNAE to receive the broadcasting SIGNALS.
similar to the invention of radios.
