Depending on the use cases, each embedded system may benefit from the communication facilities offered by the technologies described in this section. Due to the high specialization of some embedded devices, a design tailored to specific use cases may even go beyond this classification and use technologies that are designed for one specific use case. Wireless communication is impossible in some cases, due to emission regulations in some environments, and when the media is not capable of transporting radio waves reliably, such as underwater or through the human body.
Submarines may communicate by specific transceivers, using sound waves to represent the data. Special technologies have been researched ...
