• 447MHz Low-Frequency
• Long Distance Unlimited Node Availability
• Energy Saving System Mesh Type Network Configuration Remote
• Configuration Distance Expansion By Using Repeater

Unlimited node availability

• Asynchronous mesh network avoids unnecessary traffic consumption by adding CS feature inALOHA type to maximize efficiency of traffic capacity in low speed communication.
• Asynchronous structure enables efficient resources to allocate, while synchronous type has limited number of node depending onthe number of ID managed by super-frame.Asynchronous type has limit of the number of node as there is no super-frame.
• In case of 12.5kHz of narrow bandwidth in 400MHz, when synchronous network (Supposing 20byte of header-frame, and 20byte data) has 4.8kbs communication speed, up to 15ea nodes connected only, but asynchronous type does not have any limit.
• Synchronous type usesAd-Hoc process which has to get permission for network participation from master, but asynchronous type does not need any paring process as it is paired by identifying MAC address where the node is specified

Mesh type network configuration

• Mesh network does not have network disconnection problem as it automatically searches for available nodes when problem occurs in multiple nodes
• In case of tree structure, connection can be switched from a mode with problem to reserved node. However, if multiple node get a problem, the connection will be lost.
• The first mesh network in narrow bandwidth (BW:12.5khz) wireless network
• Radio shadowfree system is ideal forremote meterreading or U-healthcare

Remote configuration

• Configuration via wireless communication when necessary to change module configuration after installing device.
• ZIGBEE’s SW paring type connection does not allow multi-point control.
• Remote configuration is mandatory feature for lighting system maintenance.
