EMB-WMB868 is a 868 MHz wireless module that combines high performance to small dimensions and low cost, providing the system integrator a simple and easy way to add Wireless M-Bus connectivity and multi-hop networking into existing products. Notable features include:

  • Output power can be increased up to +15 dBm (32 mW)
  • Sensitivity up to -122 dBm
  • Extremely reduced power consumption gives access to those long-lasting battery life requirements imposed by the metering market (up to 2 μA in sleep mode with an RTC clock running)
  • Together with the Embit Wireless M-Bus Stack the EMB-WMB868 is compliant with the standard EN 13757-4:2013
  • Open platform

EMB-WMB868 modules can be provided with a W-MBus stack specifically developed by Embit for the platform that allows to integrate the module in the desired system without effort and simplify the interaction in W-MBus networks.

EMB-WMB868 modules ship programmed with EBI-WMBus which allows the customer to use the modules as a simple, ready-to-use modem (using AT-like commands over UART; see EBI protocol page for more information). The evaluation kit EMB-WMB868-EVK is strongly suggested to customers willing to develop their own firmware applications, since the kit provides all tools required to download a custom firmware on the module.
