The circles represent range of gateway and extended range of repeaters. 7SimpliciTI Network topology Active RF tags ? Active RF tags typically enter and exit the network ad-hoc. ? Tags must be able to quickly associate to the network while maintaining low power consumption. 8SimpliciTI Network topology Smoke Detector System Optional Access point CGatewaySmokeAlarm Smoke Alarm Flooded Alarm Message Sensor / Extender Examples message flows Smoke Alarm Smoke Alarm Smoke Alarm Smoke Alarm Smoke Alarm Smoke Alarm Smoke Alarm Smoke Alarm Alarm Triggered Device 9Agenda ?
