About MICS

Medical Implant Communications Service (MICS) is an ultra-low power, unlicensed, mobile radio service for transmitting data in support of diagnostic or therapeutic functions associated with implanted medical devices. The MICS permits individuals and medical practitioners to utilize ultra-low power medical implant devices, such as cardiac pacemakers and defibrillators, without causing interference to other users of the electromagnetic radio spectrum. MICS transmitters may not operate with an effective isotropic radiated power (EIRP) greater than 25 microwatts. MICS transmitter emissions are limited to an authorized bandwidth of 300 kHz and must maintain a frequency stability of +/-100 ppm of the operating frequency. Operations rules and technical regulations applicable to MICS transmitters are found within 47 CFR 95.601-95.673 Subpart E.

About WMTS

The wireless medical telemetry standard (WMTS) was officially adopted by the Federal Communications Commission (FCC) on June 8, 2000. The service rules for the equipment and use of the WMTS include limitations on transmitter output power, out of band emissions, and protection of other services. WMTS designated frequency ranges are 608 to 614 MHz; 1395 to 1400 MHz; and 1429 to 1432 MHz. WMTS generally is the remote monitoring of a patient’s health through radio technology. The use of wireless medical telemetry gives patients greater mobility and increased comfort by freeing them from the need to be connected to hospital equipment that would otherwise be required to monitor their condition. Wireless medical telemetry also serves the goal of reducing health care costs because it permits the remote monitoring of several patients simultaneously. All types of communications except voice and video are permitted on both a bi-directional and unidirectional basis, provided that all communications are related to the provision of medical care.
