Abstract: In various examples, systems and methods of dynamic channel selection for wireless communication in the presence of interference. In various examples, first interference data for a first gateway device may be determined. In some cases, a wireless transmission scheme may be switched from a static wireless transmission scheme to a frequency hopping wireless transmission scheme based on the first interference data. In some examples, the first gateway device may send first instructions indicating that the first gateway device is switching to the frequency hopping wireless transmission scheme to a first remote computing device.

Abstract: A system that improves beacon discovery by enabling a device to determine a dynamic threshold and connect to a gateway that satisfies the dynamic threshold. For example, the device may iteratively scan through available channels for a first duration of time, detecting beacon signals and storing corresponding signal strengths, then calculate a dynamic threshold value using the stored information. In some examples, the dynamic threshold value is calculated using a sum and counter implementation, with the counter incrementing with each beacon signal detected and a summing component adding the signal strength. Additionally or alternatively, the device may switch between performing first beacon discovery using a static threshold and performing second beacon discovery using a dynamic threshold. For example, the device may perform the first beacon discovery when movement of the device exceeds a threshold, while performing the second beacon discovery when movement of the device is below the threshold.

Abstract: This disclosure describes techniques for managing clock drift compensation in a network of node devices. In some embodiments, such techniques may comprise determining a current status of a network that includes a set of node devices operating in a first mode, determining, based on the current status of the network, a quantity of the set of node devices to be switched to a second mode, determining, based on one or more characteristics of individual node devices in the set of node devices, a subset of the set of node devices including a selection of the quantity of node devices from the set of node devices, and providing, to individual node devices in the subset of the set of node devices, instructions to cause the individual node devices to switch from the first mode to the second mode.

Abstract: Technologies directed to rate adaption based on both the average signal-to-noise ratio (SNR) and standard deviation are described. One method includes determining an average SNR value and a standard deviation value for a first set of RSSI samples. The method determines whether the average SNR value satisfies a first threshold criterion corresponding to a minimum SNR required with a first modulation scheme and a second threshold criterion corresponding to a standard deviation threshold. The method causes a transmitter to use the first modulation scheme for a subsequent packet, responsive to the average SNR value satisfying the first threshold criterion or the standard deviation value satisfying the second threshold criterion. The method causes the transmitter to use the second modulation scheme for the subsequent packet, responsive to the average SNR value not satisfying the first threshold criterion and the standard deviation value not satisfying the second threshold criterion.

Abstract: A method for a first network device involves transmitting, to one or more second network devices, an uplink message that includes an indication of a receive window time interval, and may also include an indication of a request for a downlink message. The method also involves initiating a scheduled receive mode that causes the first network device to transition the first network device to a first power state, and perform a receive window procedure after the receive window time interval has elapsed. The receive window procedure includes transitioning the first network device to a second power state and listening for the downlink message for a duration of time. The method further involves determining that an expiration condition has been met while the first network device is in the scheduled receive mode. Additionally, the method involves terminating the scheduled receive mode upon determining that the expiration condition has been met.
