What is wired broadband, perhaps some users are not very familiar with. Now, let's take a quick look at the difference between wired broadband and everyone familiar with ADSL.
Wired Broadband (Cablemodem) and ADSL are broadband technologies that provide access to the Internet, and the main difference between the two technologies is that the transmission medium is different from the modulation mode, the Cablemodem is transmitted via cable TV cable, ADSL is transmitted over the telephone line. In the theoretical value and expansion of bandwidth, cable technology than ADSL dozens of times times higher, so Cablemodem has an excellent broadband advantage.
Many users are curious about why wired broadband can both transmit TV signals and provide access to the Internet, why do they not affect each other? Next, I will uncover this mystery for you.
When users use Cablemodem to transmit data, they use one of the existing cable cables, and currently use coaxial cables, which divide the entire cable into three broadband. It is used for cablemodem digital signal uploading, digital signal transmission and TV program simulation number transmission. The bandwidth of the general coaxial cable is 5-750mhz, the digital signal is uploaded as 5-42mhz, the analog signal is 50-550mhz, and the digital signal is 550-750mhz. In this way, digital data and analog data will not conflict with each other, of course, can be transmitted at the same time. This is why users can also watch TV programs as they go through a wired broadband network.
