Although the concepts behind magnetic induction communication is not new, the unique formulation of magnetic induction that FreeLinc chosen, Near-Field Magnetic Induction (NFMI), is the first to capture the benefits of this technology for use in short-distance in terms of personal communications.

NFMI does not communicate using the RF properties of the electro-magnetic spectrum. Instead, it uses the magnetic field close to the transceiver (Near-Field) to sustain communications. Since NFMI does not rely on RF-based transmission for communication, it is immune to interference from nearby RF sources. By expanding and modulating this Near-Field, or what called the "personal communications bubble", Near-Field Magnetic Induction envelops the personal space of each user and is inherently private and secure.

NFMI is a system that makes far more efficient use of power - over 5 times more power efficient than typical RF-based systems.

By encapsulating the transmission within the "bubble", and limiting the range to only what the application requires, Freelinc achieves the significant benefits of:
• Dedicated communication channels
• No sharing of bandwith
• Complete frequency re-use between bubbles
• Reliable coexistence with WiFi, CDMA, TDMA and GSM
• A very substantial savings in power

Freelinc make sure you have encrypted communication.
