Abstract: An apparatus includes processing circuitry configured to output, to a plurality of devices, an initial superframe configured in an initial superframe mode of a plurality of superframe modes. Each superframe mode of the plurality of superframe modes allocating each slot of a plurality of slots for wireless communication to a first protocol, a second protocol, or a third protocol. In response to determining a change in bandwidth, the processing circuitry is configured to select an updated superframe mode from the plurality of superframe modes. The processing circuitry is further configured to output, to the plurality of devices, an updated superframe configured in the updated superframe mode.

Abstract: An apparatus for communication with a plurality of devices using time divisional multiple access (TDMA) is described. The apparatus includes processing circuity configured to for a particular duration, scan a first channel for one or more data packets being transmitted over the first channel to determine if the apparatus is experiencing signal interference. In response to determining that the apparatus is not experiencing signal interference, the processing circuitry is configured to output a first beacon at a first time using TDMA, wherein the first time is a predefined interval amount of time after an output time of a most recent beacon previously output by the apparatus. Otherwise, the processing circuitry is configured to output the first beacon at a second time using TDMA, wherein the second time comprises the first time plus-or-minus a time shift period.

Abstract: Systems and methods for avoiding potential broadcast interference between radio frequency transmissions in connected systems are provided. Such systems and methods can include determining that a first central hub device and a second central hub device are located within a potential broadcast interference range of each other and, responsive thereto, transmitting a first beacon offset sequence time to the first central hub device and a second beacon offset sequence time to the second central hub device. The first beacon offset sequence time can modify a base time at which the first central hub device is scheduled to broadcast a first TDMA beacon, and the second beacon offset sequence time can modify the base time at which the second central hub device is scheduled to broadcast a second TDMA beacon such that the second TDMA beacon can fail to overlap any portion of the first TDMA beacon.

Abstract: A system includes a sensor device, a hub device, and a keypad device. The hub device is in communication with the sensor device using time divisional multiple access (TDMA) The keypad device is in communication with the hub device. The keypad device is configured to operate in: a keypad mode and a wireless repeater mode. In the keypad mode, the keypad device is in communication with the hub device but not in direct communication with the sensor device. In the wireless repeater mode, the keypad device is in communication with the hub device and in direct communication with the sensor device using TDMA such that the keypad device, in the wireless repeater mode, acts as a wireless repeater between the hub device and the sensor device.

Abstract: An apparatus for communication with a plurality of devices using time divisional multiple access (TDMA) is described. The apparatus includes processing circuity configured to receive a signal from a device of the plurality of devices. The processing circuitry is further configured to determine, using the signal from the device, whether the device is experiencing signal interference. In response to determining that the device is not experiencing signal interference, the processing circuitry is configured to output a superframe including a first beacon at a first time, wherein the first beacon indicates a starting of the superframe. In response to determining that the device is experiencing signal interference, the processing circuitry is configured to output a time-shifted superframe including a second beacon at a second time that is different than the first time, wherein the second beacon indicates a starting of the time-shifted superframe.

Abstract: A system includes a sensor device, a repeater, and a control panel. The sensor device is in two-way communication with the repeater, and the repeater is in two-way communication with the control panel. The repeater includes a repeater module storing child table data and routing table data. The child table data stored by the repeater module, at the repeater, includes a sensor device address, sensor device descriptor, and/or sensor device status. The routing table data stored by the repeater module, at the repeater, includes channel operational information, such as a network ID, a first repeater operating channel of the repeater, a second repeater operating channel for the repeater different than the first repeater operating channel, a first information channel, and/or a second information channel different than the first information channel.
