I have in my possession a dev kit from Linx Technologies
http://www.digikey.com/product-detail/en/EVAL-433-LT/EVAL-433-LT-ND/1654265
They claim it operates at 433.92 MHz, which is only 45 kHz away from your
RFI. Their website shows:
Application Examples
- Get feedback from a security system at a safe distance
- Operate a gate remotely and confirm that it's open or closed
- Manage equipment from far away and get alerts when there's a problem
- Use RFID to track assets and inventory
