摘要: Disclosed herein are hub-based wireless networks employing end-devices at intermediate wireless at ranges of thousands of meters. End-devices may be such things as keypads, door latches, occupancy monitors, sprinkler controllers and other devices controlled or monitored in a campus or a collection of buildings. A device-initiated asynchronous mode may be used to communicate information related to spontaneous events to a hub. The hub receives packet retrial information from the end-devices, determines whether packet retrials are due to interference or some other cause such as collisions, and applies varying levels of redundancy based upon a recent history of success and failure of packet exchanges, which measurement may be a value of badness increased as errors are encountered and decreased as packet communication is successful. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.

摘要: Disclosed herein are wireless devices operable at intermediate wireless at ranges of thousands of meters, utilizing packets that include a preamble and a data payload. Devices may be such things as keypads, door latches, occupancy monitors, sprinkler controllers and other devices needing a communications link. A digital spread-spectrum frequency hopping rotation is used, wherein packet transmissions rotate through frequency sequences. A spectrum-impact-smoothed channel set is fashioned using sequences that each specify a unique preamble frequency relative to the other sequences and channels. The set is traversed as packets are transmitted, thereby distributing the focused radio-frequency emission impact of packets having long preambles over time. Packet acknowledgments are deferred until a group of packets in a stream has been exchanged. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.

The set is traversed as pacets are transmitted, thereby distributing the focused radio-frequency emission impact of packets having long preambles over time. Observance of a long- and short-period timer permits channel resynchronization between devices.

Devices may be such things as keypads, door latches, occupancy monitors, sprinkler controllers and other devices needing a communications link. A digital spread-spectrum frequency hopping rotation is used, wherein packet transmissions rotate through frequency sequences. Used is a spectrum-impact-smoothed channel sequence, each channel specifying a unique preamble frequency relative to the other sequences and channels. The set is traversed as a broadcasted stream is transmitted, thereby distributing the focused radio-frequency emission impact of packets having long preambles over time. Packet acknowledgments are deferred until a group of packets in a stream has been exchanged. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.
