Broadband (English: Broadband) is a method of transmitting many electronic information at the same time using multiple frequencies in basic electronics and electronic communication. It describes that signals or electronic circuits contain or can handle a wide frequency range at the same time. Broadband is a relative description. The larger the frequency range, that is, the higher the bandwidth, the more data can be sent. For example, in radio communication, the bandwidth with narrow frequency range can only send Morse code, and it needs more bandwidth to send high-quality music. The broadband of TV antenna means that it can receive a large number of channels. In data transmission, telephone lines are also used as signal transmission media, and optical cables are becoming more and more popular. Modem can only send 64Kbps data per second, and broadband ADSL and fiber modem can provide higher transmission rate.
