The functional foundation of hospital telemetry relies on a specialized radio frequency spectrum, designated to prevent interference from consumer electronics like smartphones or Wi-Fi. The architecture consists of three primary components: the body-worn transmitter, a high-density antenna array, and a central monitoring hub.

Transmitters capture electrical heart signals (ECG) via electrodes placed on the patient's skin and relay them to an antenna array hidden within the hospital infrastructure. This ensures a "no-gap" monitoring environment, allowing patients to remain active and move throughout the facility without being tethered to a bedside monitor. At the central station, trained technicians utilize high-resolution displays to monitor dozens of live waveforms simultaneously, enabling the immediate detection of arrhythmias or sudden clinical deterioration.
