Can data transmission by radio be tampered with?

Various password stages in our software ensure that unauthorised persons cannot gain access to the data. Because of the special structure of the data telegram, the data cannot be decrypted without being processed by our software components (radio software, device drivers). The fact that the devices cannot be assigned (local data such as the name of the tenant, flat number etc.) means that no conclusions can be drawn about user behaviour. These technical features reliably prevent any manipulation of the transmitted data within our radio systems.
