1. How does the wireless module achieve accurate and stable transmission?

The wireless modules can be classified into wireless data transmission modules, wireless monitoring modules, etc. The wireless module can realize switching signal forwarding control, collection of current and voltage signals, continuous transmission of data packets, etc., and its construction period is short, convenient and reliable. Therefore, traces of wireless modules can be seen in many equipment occasions.

What if a wireless module is used to replace the communication cable? The cable must be quite reliable. Is there a chance of packet loss in the wireless module? Actually there will be. However, it can be avoided to a great extent. The wireless module integrates functions such as retransmission mechanism, conflict concession function, and synchronization check, which greatly reduces the bit error rate. In general industrial occasions, wireless modules can meet the requirements of customers.

What to do if data is lost? The wireless module can have multiple opportunities to check and retransmit it in a very short time, which depends on the parameter setting of the customer's requirements. Of course, the retransmission has nothing to do with the transmission distance. The wireless module can transmit nearly 3000 meters using the standard suction cup antenna, and supports one-to-one and one-to-many flexible control schemes.

Therefore, wireless modules are more commonly used, practical, accurate and stable for signal transmission. You may want more information about cellular module manufacturers.

2. The wireless module is used for sharing bicycles

Today is the era of sharing, and shared bicycles can be seen everywhere. On the market, the common unlocking methods for shared bicycles are basically smart locks. Smart locks with the nature of the Internet of Things are widely used in shared bicycles. When you unlock, the wireless module on the shared bicycle sends an unlock command to the control unit, which is more convenient and quick to use.

So what are the core strengths of shared bicycle smart locks? The smart lock of shared bicycle includes central control unit, GPRS DTU module, wireless mobile communication module, charging management module, battery, kinetic energy generation module, electromechanical car locking device, vehicle accelerometer, etc., the central control unit. The wireless mobile communication module is connected with the background management system, and the position information obtained from the GPS module is sent to the background management system. After the successful identification of the background system, the communication module sends an unlocking instruction to the central control unit, and after receiving the status information of the electromechanical car locking device on and off from the background, the control pin that unlocks the mechanical lock is successfully unlocked.

When the user finishes locking the car, the locking control switch of the electronic control module will be triggered. Then the central controller informs the background management system to lock the car through the wireless mobile communication module and ends the billing after the background confirms the success.

After the above explanation, we can see that without the application of wireless modules, shared bicycles will not have the rapid development as today, and people will not experience the current convenient way of travel.
