What follows is an overview of the key points from the guide:
- Wireless M-Bus (wMBus) was first designed to meet the requirements for the automatic reading of water and gas meters, which require only a low data rate.
- wMBus requirements have expanded, as more and more industrial and commercial enterprises engage IoT applications utilising long battery life, long wireless range, and low-cost RF modules.
- It is most beneficial for difficult-to-access or remote locations, for which a wired solution could be extremely costly.
- Wireless M-Bus has impressive RF range, even over radio-challenged environments.
- Wireless M-Bus is not appropriate when pre-existing electricity and data lines run to sensor locations, or when high data rates are required, e.g., for video streaming. (WiFi or Bluetooth may be the more appropriate choice.)
