Hi
I want to know what frequency band can be used in a hospital. it is very important for healthy of patients who use electronic medical devices in hospital.
I didn't understand what to do with it. can I use 10-100 MHz frequency band . it only should not affect medical devices. it doesn't need to be in ISM band.
The frequency band is regulated by goverment. You can't just select any freqency that you want. You have to follow the FCC regulation if you are in US. You can use the ISM band without approval from FCC, but you still need to follow the EM radiation limit.
