What is the baud rate of the wireless module?

Recently, a user asked what is the baud rate of our wireless module? In the product list, the baud rate is usually not listed as a regular parameter, so some users do not understand it well, so we explain what the baud rate of the wireless module is.

The baud rate of the wireless module: official definition

In the information transmission channel, the signal unit carrying data information is called a symbol, and the number of symbols transmitted through the channel per second is called the symbol transmission rate, referred to as the baud rate, and its unit is baud (symbol / s), Baud rate is an indicator of the bandwidth of the transmission channel. Baud rate can be understood as how many symbols of data a device sends (or receives) in one second. It is a measure of the symbol transmission rate and represents the number of symbols transmitted per unit time (transmission symbol rate ). Through different modulation methods, multiple bits of information can be loaded on one symbol.

We can understand it as: how many symbols of data a device sends (or receives) in one second. The baud rate is generally used in the serial port of the computer, and there is no direct relationship with the transmission of the wireless module. When our wireless module is connected to the computer through the serial port, the role of the baud rate comes; everyone knows the concept of wireless transmission rate: the transmission rate refers to the speed at which the wireless module transmits data. When the transmission rate is higher, the transmission speed The faster, the more data can be transmitted per unit time. The baud rate is also the same in the serial port. When the baud rate is higher, the serial port transmission rate is also higher.

Summary: The baud rate is a parameter that affects the serial transmission rate of the wireless module.
