Electromagnetic radiation between pacemaker and cellular phone with the human body in close proximity

A pacemaker is a small device that’s placed in the chest or abdomen to help control the abnormal heart rhythms. Pacemaker telemetry is used for communicate with other communication devices and the suitable operating frequency used is 402-405 MHz. The issues concerning cellular phones are the electro...
