Built-in EMBee modems

 

Built-in-radio-modems-EMBee

  • ZigBee transmission protocol is based on the Ember EM250 microprocessor
  • It is fitted with 4 operating systems: ZigBee stack, OS Coordinator, OS Router, OS sleeping device      
  • Automatic reservation of network coordinator by a router in case of failure of the main coordinator
  • Easy to integrate with a help of AT-Command interface
  • Automatic networking after device initialization
  • Excellent immunity of ZigBee network
  • Total number of 65 000 operating devices in ZigBee network 
  • High security of data transmission from a coordinator to router (0.1% packet error rate)
  • Automatic set up of EMBee network by a coordinator
  • High speed of ZigBee network set up with EMBee modems; 15 min. (with 1000 modems in the same room)
  • Automatic connection from a coordinator to routers
  • Frequent optimization of routes by aggregation system of a coordinator
  • Baude Rate 9 600 bit/s
  • Network encryption available
  • Excellent immunity to other 2.4 – 2.48 GHz devices
  • Up to 16 000 networks in one building without interference
