Techniques to improve the immunity of wireless battery systems by transmitting heavily-coded signals, e.g., using multiple chips of a sequence for each bit of information, to trade data rate for interference or jamming immunity as a response once a noisy environment is identified. The techniques provide the system with a noise immunity operating mode (or high-immunity transmit and receive mode) that can improve resilience to interference or jamming by reducing the data rate. One option for reducing the data rate is by slowing down the transmission bit rate to reduce the occupied transmit bandwidth to minimize the probability of collisions with interfering signals. Another option is though digital coding methods using Forward Error Correction such as Convolutional Coding, Reed-Solomon Coding and Turbo coding. A third option is with RF spread spectrum techniques such as Direct Sequence Spread Spectrum (DSSS) or Frequency Hopped Spread Spectrum (FHSS).

High-immunity wireless communication for battery management systems

A wireless communication system includes a network manager configured to wirelessly communicate with a plurality of wireless nodes of a wireless network. The network manager and at least one wireless node include a transceiver connected to transmit and receive wireless communication via an antenna. The network manager and/or the wireless node include a cognitive engine configured to receive information regarding an environment of the wireless network as input and, in response, generate configuration data as output. Subsequent communication on the wireless network is updated using the configuration data.

Smart scheduling of TSCH networks to avoid self-interference

A wireless communication system includes at least one transmitter and at least one receiver. The transmitter is configured to establish wireless link parameters and transmit a data communication using the wireless link parameters. The receiver is configured to receive the data communication, automatically identify one or more of the wireless link parameters using the data, and extract a payload using the identified wireless link parameters. Prior to receiving the data communication, the receiver requires limited information concerning the wireless link parameters established by the transmitter. The wireless link parameters can include selectable aspects such as one or more of a transmission channel, a transmission data rate, a modulation format, a transmission power, a packet format, and a channel coding scheme.

Adaptive detection of wireless link parameters

A system and method for increasing capacity and throughput in a wireless network includes a plurality of wireless nodes configured to communicate wirelessly with one another on respective frequency channels according to a schedule. The schedule includes timeslots. For respective timeslots, first and second transmitting wireless nodes generate transmissions for a receiving wireless node. The receiving wireless node includes a receiver circuit configured to receive the transmissions from the first and the second transmitting wireless nodes simultaneously and on separate frequency channels, and a transmitter circuit configured to generate acknowledgment packets for the first and the second transmitting wireless nodes upon receipt of the transmissions by the receiving wireless node.
