4. By performing the zigzag dance, honeybees can communicate with their hive mates information about the direction and distance to patches of sunflowers yielding nectar and pollen. How honeybees go back to sunflower?

5. Like honeybees’ group communication, mesh networking is the smart-efficient way to monitor and control among the consumer electronics. Mesh Networking RadioPulse RF Chip for Smart Energy Applications Mesh Network for Smart Home Mesh Network for Smart Village

6. The name ZigBee was selected as a metaphor for the way devices on the network find and interact with one another, like the honeybees. ZigBee is a new standard for short-range wireless sensor and control networks. ZigBee Zig zag + Bee = Zig Bee Application Wireless LAN Cable replacement Control and monitor Frequency bands 2.4GHz 2.4GHz 2.4Ghz, 868Mhz, 915Mhz Battery life (days) 0.1-5 1-7 100-7,000 Nodes per network 30 7 65,000 Bandwidth 2-100Mbps 24Mbps 2Mbps Range (meters) 1-100 1-10 1-75 and more Topology Tree network Tree network Mesh network Standby current 3-8mA 0.7-1mA <1uA

8. As honeybees are dancing over the sunflower garden, they let incoming honeybees know which sunflower has more honey. The way of communication is very efficient and effective to reduce time and motion. Which sunflower has more honey?

11. Before trying one-by-one, honeybees use a ‘humming sound’ to communicate with each other and find out where honeybees are able to pour honey into. How to distribute honey in a beehive?

12. Like a humming sound among honeybees, the RF signal via ZigBee help to monitor and control the consumption of home energy. There are effectively two methods of Smart Home Energy Management Smart Home Energy Manager with ZigBee Smart Home Energy Manager with IHD Smart Home Energy Manager with ZigBee-USIM Card Air conditioner Lightings Refrigerator

16. The market for IT hardware and software of smart grid industry will exceed $171.4 billion by 2014, according to a new report from Zpryme. In the market segmentation, the smart sensor will growth up as 17.9% by 2014. Smart Grid market projection Reference: Zpryme (2009.12.). Smart Grid Hardware & Software Outlook(2009-2014).
