LoRa is a long range wireless communication technology based on spread spectrum technology. It adopts direct sequence spread spectrum with strong anti-interference and high receiving sensibility. Our LoRa module has excellent link budget. A single node covers dozens of kilometers while meeting low power consumption requirement.
AES encryption ensures the data safety in communication process effectively, even if the data is intercepted, it is difficult to crack. Our module sends out the input data after AES encryption, Only the receiving module with the same secret key can interpret data effectively. The secret key can be set by the users.
FEC (Forward Error Correction Technology) is a significant anti-interference algorithm, which can greatly decrease the error rate. Our module using self-developed FEC forward error correction and Circular interleaving algorithm improves the error correction ability and processing speed and achieves that each frame of data can be corrected 64 Bit quickly and accurately.which greatly enhance the reliability of signal transmission.
Mesh network technology is a new WLAN. Any module can be used as node and routing in mesh and a multi-hop wireless link can be established between routes.The mesh network technology adopts the on-demand routing method, and intelligently establishes a communication link according to requirements, so the network has high stability, flexible structure, wide network coverage, small transmission delay and large network capacity.
Repeating technology is to add one or more repeater nodes between nodes and responsible to re-transmission wireless signal for one time or for multiple times. Our repeater module adopts efficient anti-collision processing algorithm and time division multiplexing mechanism,automatically completing wireless signal processing, no need the intervention from the users. It is easy to use and suitable for complex environment as it effectively broadens the network covering range.
Wake-up mode is to wake up the module in sleep status through wireless way and make the module receives the data accurately. The transmitting side automatically processing the wake-up algorithm and cooperating with our super low power receiving technology makes the module run in super low power and receive data stably. This mode is very suitable for battery powered occasion.
RF RS 485, RS232 radio supports Modbus protocol, replacing wired RS485,RS232. easy installation, no wiring, low maintenance cost. It is widely used in wireless upgrading and rebuilding of wired communication equipment with RS232, RS485 interface.
Send in broadcasting way: the data sent by random module can be received by the modules with the same address and channel as the sending module at the same time.
Send in fixed-point way: random module can send data to designated module with different address and different channel from the sending module. If multiple receiving modules have the same address and channel as the sending module,they can receive data at the same time.
Data sent by random module can be received by the modules with the same address and channel as the sending module at the same time. The data is sent and received in a transparent way as what is sent is what is received. It is easy to use and suitable for transparent transmission applications, repalces UART line and 485 data line directly.
Data sent by random module can be received by designated module with different address and channel from sending module. When multiple receiver modules have the same address and channel, they all can receive data. Any module in this mode can be transmitter. The data received is transparent, not including the address or channel of transmitter.
The data sent by random module can be received by designated modules with the same channel as sending module and different addresses. If multiple receiving modules have the same address they all can receive data. Any module in this mode can be transmitter, the data received includes the address of transmitter.
Master can transmit data to designated slaves. only designated slave can receive data and output it and other slaves have no output. The data transmitted by any slave can be received and output by corresponding master. Data transmitting and receiving of slave are absolutely transparent. It is easy to use, and suitable for applications of one or more Parallel masters to multiple slaves communication.
The main feature of command mode is flexibility. Multiple commands are suitable for networking, low power consumption, wake-up,simplified transmitting(sleep - UART received data from MCU - module auto-wakeup - transmitting data - sleep). Receiver receives and outputs the address of the transmitter, which is convenient to use.
Multiple slave modules can send data to one master module at the same time. The module adopts efficient anti-collision processing algorithm and ensures that the data from each slave can be sent to master quickly and stably. The module will automatically deal with the protocol, no concern for users.
Our company came up with the concept of continuous transmission earlier. In the transmission of wireless UART module, it automatically optimizes air rate, precisely controls the interval of Wireless packet frame. Users can send data continuously in batches at one time and the receiving module continuously outputs data in batches at one time. Theoretically each time it sends infinite data packet.
Wireless data uses the technology of time division multiplexing，assisted with dynamic data processing of MCU and cache optimization algorithm，which makes the interface data of the user side continuously transmitted at high speed(115200bps) in batch and in point-point full-duplex way.
