17 Use Case 1h : Temperature Sensor Network
Month Year doc.: IEEE yy/xxxxr0 Doc.: IEEE /0301r0 March 2011 Use Case 1h : Temperature Sensor Network Pre-Conditions: User has installed a series of 5 – 20 temperature sensors throughout the home. Most of the sensors are battery operated. Application: A home automation system operates its heating / cooling / ventilation system based on temperature readings received from the sensors. The temperature sensors provide updated readings either on a periodic basis, triggered by changes in temperature, or upon request by the home automation system or the end user. Temperature sensor readings are accessible by an authorized user, while being away from home. The payload data being transmitted is around 50 byte or less no stringent latency or jitter requirements. Environment: Typical coverage of a sensor network is an entire home, the maximum number of sensors typically in the 10 – 50 range. Traffic Conditions: Potential interference from overlapping networks using the same frequency bands. Potential range extension through the use of one repeater between far away sensors and the access points Use Case: Sensors are deployed in the home in appropriate locations. A number of sensors likely to be battery operated Home automation application periodically probes sensors to report temperatures; or sensors pro-actively report changes in temperature beyond a certain threshold; or sensors proactively report temperature readings a scheduled intervals 17 Rolf de Vegt, Qualcomm John Doe, Some Company

IEEE802.11ah is going to provide an appropriate feature as a backhaul link to accommodate; the aggregated traffic of leaf sensors, and stream of camera images or surveillance videos. IEEE802.11ah hopefully performs without degradation of throughput and reliability, even if co-existing with 15.4g. I&I applications do expect the well managed co-existence.
