One to many is a common usage of LISNR's technology and can be utilized in proximity marketing and mass validation use cases. If a single speaker is the transmitter, and multiple mobile devices are the receivers, it is possible can have infinite receivers as long as they are in broadcasting range of the speaker.

If there are multiple transmitters broadcasting the same tone profile to one receiver, it is possible the tones will interfere with each other.

If more than one different tone profiles are being broadcast, a single receiver can register to listen for multiple profiles. Since they are on separate frequencies, the receiver will be able to receive tones from each profile type simultaneously.
