What are the practical differences between RF and NFMI?
To best illustrate the difference between RF and NFMI, imagine RF transmitting like a radio beacon while NFMI creates a static bubble of about 4 feet in diameter. NFMI transmission is limited to a bubble around your device and not broadcasted over long distances like a radio beacon or RF. This optimized transmission minimizes the energy transmitted, and assures that your conversation stays in your voice area. Low cost, low power, high quality of service (QoS) and a secure transmission, make magnetic induction the ideal medium for personal wireless space.
