1. Core Advantages
This module is a high-performance LPWAN communication module launched by Techphant, with 5 core advantages:
- High-speed Transmission It supports maximum 76.8 kbps air interface data rate, much higher than the 19.2 kbps of traditional LoRa modules, which makes up for the low data rate shortcoming of LoRa IoT networks. It uses a deterministic scheduling algorithm to support high concurrency and avoid signal collisions.
- Ultra-low Power Consumption Adopting next-generation low-power technology:
- Low-power mode current: only 2μA
- Wake-on-air mode current as low as 18μA Compared with traditional LoRa modules, it can retain 90% of battery power after 1 year of use (LoRa only retains 40%), effectively extending terminal battery life.
- Compact Size It adopts an ultra-small LCC SMT surface-mount package, with a size of only 17.7mm×15.8mm×2.2mm, which is suitable for integrated design of small-sized IoT terminals.
- Flexible Configuration All communication and function parameters can be configured freely, which can adapt to different application scenarios and requirements.
- Long-distance Communication It has high receive sensitivity and is suitable for long-distance networking communication in complex environments.
