EUROPEAN SMART METERS DEMAND WM-BUS AT 169 MHZ

摘要

Since its introduction in 2005 with the EN13757-4 document, the wireless MBus (wM-Bus) protocol has become the choice for many smart meter deployments in Europe due to its simple star network topology on a sub-1 GHz wireless link in the European ISM band at 868 MHz. The mass deployment of heat cost allocators in Germany in the past 6 years has proven that a wM-Bus solution at 868 MHz delivers good range even in densely populated areas with high rise buildings that are quite common in most European countries. It also allows for battery powered meters and submeters, which can work up to 10 or 15 years on one battery.
