433/868/915MHz communication

　　Wireless ad hoc network has the character as that network topology can be dynamic changed. It can quickly and automatic form an independent network between terminals. There is not center control point in the ad hoc network, and each terminal is equal, so that the ad hoc network has strong survivability and strong network self-healing.

　　The low power and wireless ad hoc network of Fcreate Energy can compatible with multiple frequency bands, such as 433MHz, 868MHz and 915MHz. The quantity of networking nodes can be more than 300. Without manual intervention, router also can be set up as required and maintained automatically, for that it has excellent network self-healing, stability and data throughout. Multiple hop transmission of signal in lighting control system can dramatically expend the network coverage and network robustness.
