  • Description

    EMB-WMB169PA is a 169 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 +30 dBm (1 W) on the EMB-WMB169PA, up to +27 dBm (500 mW) on the EMB-WMB169PAE (optimized version for highest efficiency)
    • sensitivity up to -122 dBm
    • extremely reduced power consumption gives access to those long lasting battery life requirement 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-WMB169PA is compliant to the standard EN 13757-4:2013
    • open platform

    The EMB-WMB169PA 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 WMBus networks. This makes the EMB-WMB169PA a perfect match for Automatic Meter Reading (AMR) applications.

    The EMB-WMB169PA 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-WMB169PA-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.
