LoRa Spread Spectrum Modulation Technology: LoRa spread spectrum technology enables longer communication distances. With low transmission power density, it minimizes interference with other devices. It offers high confidentiality, making it extremely unlikely to be intercepted. The technology has strong anti-interference capabilities, effectively suppressing co-channel interference and various noises. Additionally, it enhances network efficiency and eliminates interference, allowing terminals with different spread spectrum sequences to transmit simultaneously on the same frequency without causing mutual interference.

Point-to-Point and Point-to-Multipoint Transparent Transmission Modes

Point-to-Point (P2P) transmission refers to direct data communication between two devices, suitable for long-distance transmission or scenarios where monitoring points are widely dispersed.

Point-to-Multipoint (P2MP) transmission, which is slightly more complex, experiences greater signal loss during transmission compared to point-to-point (one-to-one) transmission. Therefore, it is suitable for situations where monitoring points are more concentrated, numerous, and the transmission distance is relatively short.

Functional Features of Data Transmission Radios

The data transmission radio supports a wide voltage input range (9-30V), making it suitable for various power supply environments. It features ultra-long-distance communication capabilities and a dual-antenna design, ensuring signal stability and reliability. The module has a built-in RS485 interface with an isolation circuit, providing electrostatic protection and standing wave protection, ensuring safe operation in harsh environments. It uses a custom aluminum alloy housing to enhance durability and heat dissipation performance.

The device also features a built-in hardware watchdog reset circuit that automatically restarts the device in case of anomalies, ensuring continuous and stable operation. Additionally, it has strong anti-interference capabilities, effectively resisting external strong interference signals, further enhancing the device's reliability and stability.

Multiple protection functions, such as reverse power protection, over-connection protection, and antenna surge protection, significantly increase the radio's reliability.

Operating temperature range: -40℃ to +85℃, suitable for various harsh working environments, truly an industrial-grade product.

Selectable hop count in MESH mode: In MESH mode, the device allows users to select the hop count for data transmission. This feature optimizes network topology according to specific needs, controls transmission delay, and ensures effective data delivery in complex multi-hop networks, thereby enhancing network flexibility and reliability.

MESH self-organizing network: Developed by NiceRF, the MESH algorithm features automatic routing, forming a network transmission system with no blind spots and no distance limitations.

Precautions for Using High-Power Wireless Data Transmission Radios

Select a suitable DC regulated power supply with strong high-frequency interference resistance, low ripple, and sufficient load capacity. It is also necessary for the power supply to have overcurrent protection, overvoltage protection, and lightning protection functions.

Do not use the radio in environments that exceed its specified characteristics, such as high temperatures, high humidity, low temperatures, strong electromagnetic fields, or dusty conditions. These environments can significantly wear down the radio, shorten the lifespan of internal components, and cause substantial signal attenuation in strong electromagnetic environments, hindering wireless signal transmission.

The ground wire of the data transmission radio should be well-connected to the ground wire of external devices (such as PCs, PLCs, etc.). Otherwise, it can easily damage the communication interface or cause signal transmission instability, leading to errors and other issues.

Antenna Selection Precautions for Data Transmission Radios

To ensure optimal communication distance for the module, follow these principles during antenna usage:

Antenna Positioning: Avoid placing the antenna close to the ground surface and keep it away from obstacles.

Magnetic Base Antennas: If using a magnetic base antenna, straighten the lead wire as much as possible, and attach the base to a metal object.

Yagi Antennas: For Yagi antennas, it is recommended to place the transmitting antenna vertically and the receiving antenna horizontally.

Note: Due to the high power output, ensure the antenna is connected before the radio starts transmitting to avoid damaging the internal power amplifier module.

Antenna Distance: The distance between the receiving and transmitting antennas should be greater than 1.5 meters.
