Is there any theoretical room for wireless communication that does not require EMF and would be unhindered by RF blocking materials or Faraday cages?
Digital or analog has to do with your message encoding/decoding scheme, not the medium of transmission. You could certainly use acoustic waves digitally.Theldiot said:Hahaha That's embarrassing. I was wondering about digital communication, though.
That's not a meaningful distinction - all communication is analog at the physical level.Theldiot said:I was wondering about digital communication, though.

For an example of sound used to carry digital data... Google for "acoustic coupler"
jtbell said:Is electromagnetic radiation in the visible frequency range, i.e. light, acceptable? Modulating light to carry a digital signal is well-established technology.
Theldiot said:Would it be theoretically possible for quantum tunnelling to enable digital communication? And could this be used over long distances?

Very, very slowly. Google: hipster douc -- er, "retro" rotary phone:Vanadium 50 said:That's no phone! How do you text?
Some even digital!There were various methods of wireless signalling that do this: semaphore, Aldis lamps, etc.

Non-EMF wireless communication refers to wireless communication technologies that do not use electromagnetic fields (EMF) to transfer data. This includes technologies such as infrared, laser, and acoustic waves.
Traditional wireless communication, such as Wi-Fi and Bluetooth, use electromagnetic waves to transmit data. Non-EMF wireless communication, on the other hand, uses different forms of energy to transfer data, such as light or sound waves. This makes it an alternative option for those who are concerned about potential health risks associated with EMF exposure.
One of the main benefits of non-EMF wireless communication is the reduced exposure to electromagnetic radiation. This can be particularly beneficial for individuals who are sensitive to EMF or for use in areas where EMF interference may be a concern, such as hospitals or airplanes.
Some examples of non-EMF wireless communication technologies include infrared data transmission, which is commonly used in remote controls, laser communication, which is used in satellite communications, and acoustic communication, which is used in underwater communication systems.
One potential drawback of non-EMF wireless communication is its limited range compared to traditional wireless technologies. Non-EMF wireless communication also requires a clear line of sight between the transmitter and receiver, which may not always be possible in certain environments. Additionally, some non-EMF technologies may have slower data transfer rates compared to traditional wireless options.
