ECG Wireless Telemetry

Biotelemetry is defined as transmitting biological or physiological data to a remote location that has the capability to interpret the data and affect decision-making. Biomedical telemetry is a special field of biomedical instrumentation that often enables transmission of biological information from an inaccessible location to a remote monitoring site. Telemetry is the science of gathering information from a distant location and then transmitting the data to a convenient location to be examined and recorded. Telemetry is a process by which transmission of objects or environments characteristics via different transmission channels is conducted. Air, space for satellite application, coaxial cable or fiber optic cables are used as transmission channels. Wireless telemetry systems are used when the measurement point is far from the monitoring place or there is a risk for work safety. Wireless telemetry systems are preferred at biotelemetry application because of the fact that biological signals can be observed in natural living surrounding.
