Common Questions
- Tell FNRF your target country before choosing frequency and certification documents.
- RF range depends on antenna, enclosure, ground plane, height, and interference environment.
- For battery products, send standby current and wake-up requirements before sampling.
What To Test First
- Pairing behavior and output interface in your controller.
- Distance test with your enclosure and antenna position.
- Power consumption, supply stability, and motor/noise interference.
Need model selection help?
Send your target frequency, distance, voltage, antenna space, interface, and estimated quantity. FNRF can recommend a matching transmitter, receiver, antenna, and demo kit.
