#### 5.2.2 Adaptive Data Rate Algorithm for Network Performance Optimization
In future work, the LoRa communication characteristics inside the building environment can be explored, while by combining with techniques such as transfer learning or few-shot learning, the flexibility and adaptive capability of the system can be further enhanced, especially when facing brand new scenarios or environments with sparse business data; the system will be able to adapt faster to different deployment environments or new network conditions, and utilize a small amount of data for rapid learning and adjustment,, This further enhances the system's adaptive capability.
