  • Patent number: 12317393
    Abstract: To commission a plurality of nodes (200) to a network (100), a proximity-based commissioning has certain benefits. However, to get a proper proximity estimation in an area with a large number of nodes (200) deployed in a dense network may not be an easy task. To address this problem, nodes (200) to be commissioned are configured to spend most of its time on detecting beacons from a commissioning device (300) to derive proximity information in a one-to-many topology. And then the node (200) is further configured to feedback the proximity information to the commissioning device (300) at an adaptive beacon rate to further assist the commissioning device (300) to implement the proximity-based commissioning.

  • Patent number: 12294410
    Abstract: High-speed optical communication is very attractive to satisfy high throughput applications. In the meanwhile, it is also desirable to reduce the energy waste resulted from an idle state of the optical transceivers of the communication system. The present invention discloses that both the access point (1200) and the end point device (1100) can operate in at least two different operation states, a normal operation state and a low power state. The low power state is a default state, and the normal operation state is enabled only when a valid trigger is detected. To establish a high-speed optical link (60), the end point device (1100) first sends an optical trigger signal (50) to the access point (1200) in the low power state. The access pint (1200) switches to the normal operation state only when a valid trigger signal is identified after detecting the optical trigger signal (50).
