The secret sauce of CHCH-004 is its adaptive data rate (ADR). The chip automatically adjusts its transmission speed based on signal strength. If a sensor is close to the receiver, it blasts data fast to save power. If it's far away in a basement, it slows down the bitrate to ensure the packet arrives intact.

To understand the performance metrics, you must look at the datasheet. The CHCH-004 chipset typically boasts the following specifications:
