The Core Architecture of Wireless Medical Telemetry Systems (WMTS)
The functional foundation of hospital telemetry relies on a specialized radio frequency spectrum designated by the FCC to prevent interference from everyday devices like cell phones or Wi-Fi.
The Transmitter: A small, battery-powered pack carried by the patient. It is connected to the body via electrode lead wires (typically 3 to 5 leads) that capture electrical heart signals (ECG).
The Receiving Antenna Array: Strategically placed throughout the hospital—often hidden above drop ceilings—to ensure "no-gap" coverage as the patient moves or exercises.
The Central Monitoring Station: A dedicated hub (sometimes called a "War Room") where technicians and nurses view live waveforms. In 2026, these stations often utilize high-resolution displays that can monitor up to 64 patients simultaneously on a single screen.
