LoRa Point-to-Point Module FAQs
Long-distance communication: LoRa technology is able to achieve communication distances of several kilometers in urban environments, and even tens of kilometers in suburban or rural areas.
Low Power Consumption: Designed to run on battery-powered devices for extended periods of time, significantly extending the life of your device.
Strong anti-interference: Using direct sequence spread spectrum (DSSS) technology to improve the signal’s anti-interference ability and receiving sensitivity.
Easy to deploy: Supports multiple networking forms, such as point-to-point, star, tree, etc., simplifying the deployment and management of large-scale IoT networks.
Environmental factors: For example, the ground absorbs and reflects radio waves, and the test effect is poor close to the ground; when there are straight-line communication obstacles, the communication distance will be attenuated; there are metal objects near the antenna or placed in a metal shell, and the signal attenuation is serious; Seawater has a strong ability to absorb radio waves, and the test results at the seaside are poor.
Equipment factors: such as low power supply voltage, wrong power register setting, too high air rate setting, poor matching between antenna and module, or antenna quality issues, etc.
External interference: such as temperature, humidity, co-channel interference, etc.
Optimize antenna selection and installation to ensure that the antenna matches the module and is kept away from metal objects and sources of electromagnetic interference.
Check the power supply to ensure that the voltage is stable within the recommended supply voltage.
Adjust power register and air rate settings to balance transmission distance and power consumption.
Try to avoid using it in complex environments (such as high-rise urban areas) to reduce signal attenuation.
LoRa point-to-point modules usually communicate with other LoRa devices wirelessly. In point-to-point communication, two LoRa modules exchange data directly without the need for a central control node.
If you need to communicate with other types of devices (such as Wi-Fi, Bluetooth, etc.), you may need to perform protocol conversion and data forwarding through a gateway or other intermediate device.
