LFMC-V4 Magneto-Inductive Communication Module
Engineering evaluation module for short-range, low-rate UART communication in selected underwater, underground, confined, and RF-limited environments.
Discuss Your ApplicationProduct Overview
The NovaLynx LFMC-V4 is an engineering evaluation module designed to assess short-range, low-rate data transmission through a magneto-inductive communication link.
Connected to a host controller through UART, the module can be evaluated for control commands, telemetry, sensor readings, device status, alert signals and recovery data in selected underwater, underground, confined and RF-limited environments.
Current Evaluation Profile
| Link role | Control, telemetry, sensor, status, alert and recovery data |
| Host interface | UART |
| Communication mode | Half-duplex |
| Current link rate | 500 bps |
| Typical evaluation range | 10–15 m, subject to test conditions |
How It Works
The transmitting module converts digital data from the connected host into a controlled alternating magnetic field. The receiving module detects the magnetic-field variation, demodulates the signal and outputs the recovered data through UART.
The current LFMC-V4 operates as a half-duplex link. Each unit can perform transmitting and receiving functions within the communication process.
Host Controller → UART → LFMC-V4 Transmitting Module → Magnetic Induction Link → LFMC-V4 Receiving Module → UART → Receiving Host Device
Suitable Link Roles
The current evaluation module can be reviewed for the following low-rate communication roles:
- Control commands
- Telemetry data
- Sensor readings
- Device status
- Alert signals
- Recovery data
The current LFMC-V4 is positioned for low-rate data transmission rather than broadband video or high-throughput networking.

Note: Specifications reflect the current engineering evaluation unit. Actual link performance may vary with coil orientation, spacing, installation geometry, operating medium and surrounding electromagnetic conditions.
Installation and Link Geometry
Magneto-inductive communication is sensitive to the relative orientation of the transmitting and receiving coils. The LFMC-V4 produces a directional field pattern, and partial blind zones may occur when the modules are positioned unfavorably.
For initial evaluation, the two modules should normally be positioned approximately parallel. Perpendicular placement may significantly reduce signal strength. Adjusting the angle of one module may help restore the link when it enters a blind zone.
Potential Evaluation Environments
- Underwater equipment and monitoring platforms
- Underground inspection and tunnel applications
- Confined-space industrial robots
- RF-restricted or shielded environments
- Independent alert or recovery links
Application Boundaries
The current LFMC-V4 is not positioned as a broadband video system, a long-range replacement for RF, a universal through-material communication link, or a direct substitute for fiber-optic or acoustic communication.
NovaLynx reviews the required data type, operating medium, communication distance, installation geometry, host interface, available power and platform constraints before recommending a communication path.
