Controller Based WLANs

Q:

How can you relate human metaphors towards wireless fundamentals?

Transmitter - The Human voice

Transmit cable loss - Something that reduces the volume of speaking before it can reach anything that might increase it, e.g. tape over one’s mouth

Transmit antenna gain – Something that passively amplifies the voice volume, e.g. a speaker’s cone (a bullhorn would be more of an active transmit amplifier)

Distance – How far apart the origin of the sound is from the hearer’s ear (it gets harder to hear the same volume over greater distances)

Receive antenna gain – Something that passively amplifies the signal received by the hearer, e.g. a hearing trumpet (a hearing aid would be more of an active receive amplifier)

Receive cable loss – Something that reduces the volume heard before it can reach anything that might process it, e.g. wearing ear plugs

Receiver – The Human ear

Receiver sensitivity – The acuteness of the hearer’s hearing

Ambient noise – Anything that might interfere with being able to hear what is spoken, e.g. hearing across a crowded room full of other people speaking loudly
