Patent number: 12069516Abstract: Technology for wireless transmission and reception of messages is disclosed. The disclosed technology includes detection and/or reception of messages in a manner in which the receiver latency for a message is automatically adjusted for each particular message. For example, the receiver latency for each message may be automatically adjusted based on channel conditions, e.g., instantaneous channel conditions, between the transmitter and receiver at the time that message is transmitted/received. For example, the receiver latency for a message may be proportional or otherwise associated with to the signal-to-noise ratio (“SNR”) at the receiver at the time that message is received.Type: GrantFiled: May 30, 2021Date of Patent: August 20, 2024Assignee: SpectraNet, Inc.Inventor: Jeffrey C.
