doc.: IEEE 802.15-11-0xxx-00-004K Submission March 1, 2010 Huawei Slide 2 Smart Agriculture: Emergent WSN markets Huge Population, Motorization and Bad Weathers Challenge Chinese Agricultures High-efficient, Smart operation is only choice for Chinese Agriculture. Millions Green Houses Supports current Agricultures in all northern China. Large-Scale farmland monitoring are expended nationally. The national smart agriculture market for WSN tech and products is > 10B RMB 。

WSN for in Smart Greenhouse environmental control system - An economic WSN organizes sensors and controllers easily for greenhouse autonomy and product heavy Battery Power supporting is mandatory. Expect Battery operation lasts over 2 yr, even longer.
doc.: IEEE 802.15-11-0xxx-00-004K Submission March 1, 2010 Huawei Slide 4 Detail Example – ELC-WSN in Irrigated Agriculture Extra Low Consumption Wireless Sensor Network (ELC-WSN) nodes are deployed in farmland and collect the soil moisture periodically. The soil moisture data is transmitted to flow rate controller of water pump. The pump optimizes the irrigation schedule so as to increased crop water productivity and improved yield quality. For there is no power in crop field and sensor nodes require as small as enough not to influence the farming work of tractor and monitoring time is usually very long, at least one year, sensor nodes must have very low energy consumption. ELC-WSN Sensor node flow rate controller of water pump This is also the answer why extra power consumption is so critical on the application.

Transmission distance - one hop distance may be ~ 100m and with good diffraction performance in different environment Networking - networking must be easy to re-deploy by self due to the fast- changing environment and less tech supporting. - networking size should be scalable and cover KM 2 area.

Transmission distance - one hop distance ~ 100m Energy consumption - The applications have to share the battery power with calls, Network - The network must be easy to re-deploy due to the fast-changing layout of the public areas. 802.15.4 Low data rate (20 to 250 kb/s) Short distances (10 to 100m) Multi-year battery life Little or no infrastructure
