1. A system comprising:
a control panel having a first wireless transceiver that operates under a IPv6 over Low Power Wireless Personal Area Network (WPAN)(6LowPan)/Internet Protocol version 6(IPv6)/Internet of Things(IoT) protocol, wherein the 6LowPan/IPv6/IoT protocol supports one or more of a 6LowPan protocol, an Institute of Electrical and Electronics Engineers(IEEE)802.15.4 protocol, and IEEE802.11 coordination;
a plurality of remotely located, wireless devices, wherein each of the plurality of remotely located, wireless devices has a respective second wireless transceiver that exchanges first messages with the control panel within a respective one of a plurality of time division multiple access (TDMA) slots on a radio frequency (RF) channel; and
a first processor within the control panel and a respective second processor within each of the plurality of remotely located, wireless devices that control transmission and reception of the first messages within the plurality of TDMA slots of a repeating super frame,
wherein at least some of the plurality of remotely located, wireless devices select the respective one of the plurality of TDMA slots of the repeating super frame under a carrier sense multiple access with collision avoidance (CSMA/CA) algorithm/mechanism and some other of the plurality of remotely located, wireless devices select the respective one of the plurality of TDMA slots of the repeating super frame under a WiFi protocol,
wherein a first set of the plurality of TDMA slots is reserved for remotely located, wireless devices of the plurality of remotely located, wireless devices operating under the 6LowPan/IPv6/IoT protocol,
wherein a second set of the plurality of TDMA slots is reserved for remotely located, wireless devices of the plurality of remotely located, wireless devices operating under the WiFi protocol, and
wherein the first wireless transceiver of the control panel transmits a beacon that identifies a temporal location of the first set of the plurality of TDMA slots to the at least some of the plurality of remotely located, wireless devices.
