Tính năng của sản phẩm:

●  Strong Penetrating Ability, Long Transmission Distance (2-11.5km)
●  Strong Anti-interference Ability and Reliable Transmission
●  Low Consumption and Multi-stage Dormancy
●  Multi-adjustable Transmission Power

Remarks:

F8L10D module can choose from the following frequencies: 410-441MHz or 863-870MHz.

F8L10S module can choose from the following frequencies: 410-441MHz.

Low Power Consumption, Multi-Stage Sleep Mode <1.8uA

The two biggest problems to wireless communications is transmission distance and power consumption. Through several rounds of hardware engineering improvements and software optimizations, the Four-Faith LoRa module requires only 1.8 uA of current while dormant. Combining multi-level adjustable transmitting power, multi-level sleep modes, over the air wake up and other power optimizing techniques, the module is able to operate under ultra low power consumption while transmitting data over a long distance, a clear advantage over battery-powered applications

Excellent Anti-Interference Features

Using the forward error correction technology to increase redundant information during transmission, any errors are corrected immediately upon arriving at the receiving end. Combine this with the Four-Faith channel conflict detection optimization technique to solve the problem of node data and packet loss to greatly improve the link robustness.

Module Supports Over-the-Air Updates

The Four-Faith LoRa modules support over-the-air updates along with remote maintenance, so technical personnel need not be on site to perform these tasks, significantly reducing labour costs and improving management efficiency. 

Ultra-High Receiver Sensitivity

Modulation techniques created a unique spectrum widening process, allowing the receiver sensitivity to reach -148dBm. This makes it suitable for use in environments where stable long-distance data transmission is a top priority

Large Network Capacity, Flexible Networking, and Low Cost

The LoRa network can connect and link tens of thousands of nodes, according to the needs of the project the number can be changed accordingly. With good network scalability, low cost and no data charges, the overall operating costs are lower which is an evident advantage for large-scale projects

Easy to Embed and Develop

The Four-Faith LoRa module is only the size of a one Yuan coin, with a very small volume but providing a variety of forms of antenna connection, creating flexibility to embed it on a range of devices. Four-Faith has developed a complex low-level LoRa protocol; the customer only needs the serial port to transmit application data
