What I learned
The first set of EOTO presentations was about communication technology through the years. My assignment was to research the history and role of emojis and emoticons in communication. I learned a ton from my classmates presentations on their assigned technologies.
I was able to pair up three technologies I heard about and relate them to each other.
Here’s what I gathered…
Telegraph -> Radio -> Bluetooth
1800’s 1920’s 1999
The first technology in history that eventually lead to Bluetooth that we use so much today was the telegraph. The telegraph worked using electro magnetic spectrum sound waves to transcribe a message from a long distance. The first long distance message was communicated from Baltimore to DC.
Following the Telegraph was the invention of radio which was invented in the 1920’s. This played off the telegraphs technology of sound waves but allowed much more widespread communication streamlining.
Leading up to the invention of Bluetooth, was the technology from Apple, called FireWire .
This technology was only compatible for connecting 2 Apple devices to each other. This was nice for Apple’s business, but not very practical in the greater sense of what Bluetooth would eventually accomplish.
Finally the greatly awaited Bluetooth came around in 1999. This technology was named after a German king who actually had a blue tooth. This technology works off of radio frequencies, but allows the connection between any device compatible with Bluetooth (which is a lot). Some examples include phone to car connections that can transmit map directions, music streaming, phone calls and more. Garage door openers are another thing people may not realize use the technology of Bluetooth. The army has benefited greatly from this invention and it continues to get better each year. Originating from Bluetooth 1.0 and progressing to 5.0 (as of 2021) Bluetooth gets a faster connection on a longer geographical range nearly every couple of years.
