| In no doubt, IoT is network oriented – even the name IoT naturally relates to the Internet network. Communication is an essential part of IoT idea. Every IoT device must communicate somehow, even most simple, passive RFID tag – it responds with some data to the excitation. | In no doubt, IoT is network oriented – even the name IoT naturally relates to the Internet network.

| Communication is always performed with some rules known for both communicating parties. Like people have their different languages to use, devices have protocols. Communication protocol describes how to address the information to the remote device, how to encode the data, how to check the correctness of the incoming message. The physical layer of protocol description also tells how to transmit every bit of data, what is the frequency of radio waves, how fast we can send the data, what is the maximum range of the transmission. | Communication is always performed with some rules known for both communicating parties.
