Network supporting TDMA and CSMA based devices

A hybrid slotted time division multiple access (TDMA) and carrier sense multiple access (CSMA) based networks that optimize radio frequency (RF) based network resources, RF infrastructure, and improve network performance in a building which may include time critical sensors, such as smoke sensors, and non-critical sensors. The present system may classify critical sensors as guaranteed sensors which get TDMA slots assigned by a network manager. The non-critical sensors may operate in non-guaranteed CSMA slots but within a predefined latency interval. The present system may provide for both types of sensors to co-exist in tandem within the same wireless network.
