W-MBus, or Wireless M-Bus, is a communication protocol designed for meter reading and data transmission in smart utility applications, particularly in water, gas, and electricity metering. It allows devices to communicate wirelessly in a low-power and efficient manner, making it suitable for smart meter networks.
The protocol is based on the European M-Bus standard (EN 13757-4) and enables various devices to connect and transmit data over short distances. W-MBus is commonly used in smart city infrastructure and Internet of Things (IoT) deployments due to its reliability and energy efficiency.
Key features of W-MBus include:
Low energy consumption, enabling long battery life for devices.
Supports various modes of operation (S1, S2, T1, T2), providing flexibility depending on application needs.
Secure data transmission capabilities.
It's particularly beneficial for applications such as remote meter reading, where frequent data collection from multiple devices is required without extensive wiring.
