Basic Definition of Industrial Wireless Modem

2018.07.31
Industrial wireless modem is the abbreviation of Modulator and Demodulator. It is a device that converts digital signals into analog signals by the modulator at the transmitting terminal and converts analog signals into digital signals by the demodulator at the receiving terminal.

Modulation is the conversion of digital signals into analog signals that are transmitted by the telephone line; and demodulation, that is, the conversion of analog signals into digital signals. They are collectively called industrial wireless modem.

Modem acts as an interpreter for analog signals and digital signals. There are two kinds of electronic signals, one is "analog signal" and the other is "digital signal". The telephone lines transmit analog signals, while the PC transmits digital signals. So if you want to connect your computer to the Internet through the telephone line, you must use a modem to translate these two different signals. After connecting to the Internet, when the PC sends the information to the Internet, as the telephone line transfers the analog signals, it is necessary to use a modem to "translate" the digital signals into analog signals. This process is called "modulation". When the PC gets the information from the Internet, the information that is transmitted from the Internet through the phone line is analog signals, so if the PC wants to understand these signals, it needs a translator, that is, the modem, and this process is called "demodulation". The two processes are collectively called "modulation and demodulation".
