1. Ada indicates that the module is an adaptive module whose firmware is used for adaptivity and receiver-blocking test. An adaptive module is often used in CE certification.
2. Rad indicates that the module is a fixed-frequency radiation module, which contains fixed-frequency firmware without an RF cable. A fixed-frequency radiation module is used for testing radiated spurious emission and other radiation properties in a certification.
3. Con indicates that the module is a fixed-frequency transmission module, which contains fixed-frequency firmware with an RF cable. The RF cable has an SMA connector, which connects to a spectrum analyzer or other testing equipment.
