The high-performance wireless transmission and reception device for transmitting digital signals through wireless mode, which integrates the underlying protocol of wireless communication, makes complex wireless transmission and applications simple.
The radio only needs to be connected to RS232 or RS485 to send and receive data. It is used like a wired serial port and can be widely used in PLC wireless communication; data acquisition equipment, monitoring equipment, medical equipment, and electronic instrumentation automation control; Heating automatic meter reading charging system; LED screen wireless transmission of text, pictures and wireless control; video surveillance PTZ control, access control attendance card reader, etc.
Adopt cyclic interleaved convolution matrix coding + FEC forward error correction, powerful error correction capability.
Using advanced LoRa spread-spectrum technology, the transmission distance and penetration capability are more than doubled compared to traditional FSK.
Narrowband transmission power density is higher than ordinary communication power density, and the transmission distance is more than twice.
The wireless serial port supports air wake-up and is suitable for various battery-powered applications.
The lower the frequency, the stronger the diffraction and penetration capabilities of the module.
This module frequency band is the national power grid measurement frequency band, with stable and reliable performance, good diffraction capability, longer transmission distance, and good anti-multipath attenuation effect.
