RS-485, also known as TIA-485, is a differential serial communication standard defined by the Telecommunications Industry Association (TIA). It extends the capabilities of RS-232 by enabling long-distance, multi-node data transmission over a balanced twisted-pair cable. Unlike RS-232 (point-to-point), RS-485 supports multi-drop networks (up to 32 devices per bus) and operates over distances up to 1200 meters, making it ideal for industrial automation, building controls, and IoT systems.

Millimeter wave refers to electromagnetic waves with frequencies ranging from 30GHz to 300GHz, characterized by extremely short wavelengths (1mm to 10mm). It boasts abundant bandwidth resources, capable of supporting data transmission rates of several Gbps per second or higher.
