20180241254 | Low Jitter Event Synchronization Across Communication Links - Various embodiments use prospective synchronization signals early in the signal reception to adjust framing cycles of communication nodes to reduce jitter. Some embodiments temporarily suspend messaging between existing nodes of a communication system while instructing new nodes to generate a beacon according to a beacon schedule. The system can monitor for responses from the new node and calculate a timing error. This timing error can be sent to the new node to adjust cycle framing. In some embodiments, these techniques for timing the receive (Rx) and transmission (Tx) cycles of a node (e.g., a client wireless antenna system) can be utilized such that the radio frequency (RF) energy received between RF energy cycles can be delivered directly to the node, stored in a client's battery by a wireless charging system, enhance the Rx signal opportunities, or make the integrity of the delivered Tx signal more efficient. | 2018-08-23 |
