Description
1. Long communication distance, strong anti-jamming capability, flexible network and stable performance.
2. Functions: Coordinator, Router and End-Device.
3. The Central Coordinator is the central nodes which can automatically initiate maintain and manage the information of the network. The Router takes the charge of liking network together, transmitting the data and associating with other routers and End-devices. And the terminal nodes only send and receive the data.
