The Federal Communications Commission (FCC) has expanded the frequency associated with the Medical Implant Communications Service (MICS). The core band is at 402–405 MHz, but the commission has added 2 MHz of newly designated spectrum (401–402 and 405–406 MHz) in the bands bookending the original range. The MedRadio Service accommodates body-worn and implanted medical devices, "including those using either listen-before-talk (LBT) frequency monitoring or non-LBT spectrum access methods, in designated portions of the 401-406 MHz band," according to the commission’s summary statement.
