#bluetooth #lora #868mhz #wifi #2decimal4ghz 2.4GHz does not go through normal coated glass windows that are universal in Germany. How can I communicate wirelessly through my windows with devices outside? Is there a #transducer available e.g. radio to #optical to #radio ? Do I have to use a laser or led signal? Thanks for any tips.

The difference between a #Transformer and a #Transducer is that a transformer can reformulate (modify the form) of the same substance, while a transducer can reproduce the form observed in one kind of substance into the same form but in another type of substance. This kind of reproduction is usually called the #model.

People often “blame” Shannon’s theory of #communication for completely ignoring #meaning, maybe also because Shannon himself stated that “the semantic aspects of communication are irrelevant to the engineering aspects“😀
However, if one recognizes that the #information content as defined by the #entropy is the measure of #uncertainty in a receiver about the sender’s #state when producing the message, can it perhaps be interpreted that the receiver is trying to #understand what the sender was #meaning to send?
The information the sender encodes in the message is never the same as that the receiver decodes from it on the other side of the channel.
Below is Shannon’s description of the standard #transducer used for encoding and decoding the information in messages. The block diagrams are my rendering of the description (F is a “#memory” function):

The use of the terms #transformer and #transducer seems somehow different in #AI than in other #engineering disciplines.
In engineering a “transformation” means altering the #form of the same #substance and “transduction” is used when the form is “produced” in another (different) substance.
For example, a #transformer will change (reduce or increase) the voltage “pressure” of an AC current source while a #transducer such as a microphone will change an acoustic pressure (wave) to an electric signal.

#askfediverse I'm looking into turning a window into a speaker. Anyone know of low budget solutions for that? A #transducer , but what #amplifier goes together with it?
Pretty much low budget. Thanks!
