Communication system using orbital angular momentum
View Patent ↗Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures may utilize orbital angular momentum to deliver more bandwidth across multiple channels than any single communication channel can carry. In some implementations, the communication architectures distribute data across multiple orbital angular momentum channels in a bonded channel group.
