Guide: 5G replaces the fiber-optic broadband network, not just a mobile phone problem, which involves all aspects of the next-generation network, from technical standards, transmission modes, down to terminal support, etc., there are too many things to update and iterate!

Is it possible for 5G to replace fiber-optic broadband?

5G is the fifth-generation mobile communication technology. The 5G network should satisfy at least several characteristics: the peak rate reaches 10Gbps, which is equivalent to 100 times faster than the 4G transmission rate of 100Mbps, and the 5G network delay is shortened from 4ms to 50ms for 1ms, satisfying 100 billion. Level network terminal connection, the unit bit energy consumption of the entire mobile network is 1000 times lower than 4G.

Optical fiber broadband is to convert the data to be transmitted from electrical signals to optical signals for communication. At each end of the fiber, "light cat" is installed for signal conversion. Optical fiber broadband is the most ideal one among multiple transmission media in broadband networks. It is characterized by large transmission capacity, good transmission quality, low loss, and long relay distance. The optical fiber transmission uses wavelength division multiplexing (WDM) , that is, the Internet data of multiple users in the cell is aggregated into a high-speed signal by using PON technology, and then the optical signals modulated to different wavelengths are transmitted in one optical fiber.

It is basically impossible to replace fiber-optic broadband with 4G in the short term.

Understand the concept of 5G and fiber-optic broadband. Let's talk about whether 5G can replace fiber-optic broadband. How to replace it? When can it be replaced?

Before the analysis, briefly explain the principle of mobile communication technology, which is easy to understand.

The most important change in 2G networks compared to 1G is the use of digital signals between mobile phones and base stations to increase system capacity, which is more efficient than analog signal transmission, and digital signal security is better than analog signals.
