What does transparent transmission in communication networks mean? [Copy link]

1. Transparent transmission: refers to a data transmission method that is independent of the medium, modulation and demodulation method, transmission method, and transmission protocol of the transmission network.
This is like express mail, which may reach you through a combination of bicycles, cars, trains, and airplanes, but you don’t need to care about what they have experienced in between.

2. Why do we need transparent transmission?
Transparent transmission is generally used to read remote serial port data. For example, every user in an Internet cafe must swipe their ID card to access the Internet, but the ID card database cannot be placed in every Internet cafe. Therefore, the serial port data of the card reader is transmitted back to the public security bureau through transparent transmission, and the ID card number is compared on the platform of the public security bureau.

Thanks to the OP!

I would like to ask the OP if he can provide wifi coverage. For example, if you have a room of more than 100 square meters, you want to provide wifi coverage for the whole room. The current situation is: with only one wireless router, there is no signal or the signal is too weak in many places.

The other party can use the transparent data as soon as it is received, without any excessive processing.

In this case, you can add wireless AP to extend the coverage, which is the most common method. There are also other types of extension devices available. If you do not add equipment to extend the coverage, the only way is to replace the existing wireless router with a high-gain antenna or even a high-gain directional antenna, but this method depends on whether the device supports the replacement of antennas, and it may not necessarily solve the coverage dead spot problem, but can only improve it.

Also, this type of question should be posted separately, so that you have a greater chance of getting help.
