[W-MBUS] What kind of encryption is supported in the Wireless M-Bus modules?

Currently the transport layer mode 5 (AES-128-CBC) and extended link layer encryption mode 1 (AES-128-CTR) is supported. New encryption modes are added as the Wireless M-Bus standard develops.

[W-MBUS] “I have been asked to evaluate the possibility of incorporating a wireless MBus solution into an existing wired MBus device and came across your products in a technical magazine. What other additional devices, other than the module, may be necessary to create a small scale network. We are familiar with all aspects of electronic design so need only the basics. “
[W-MBUS] “We are interested in using Radiocrafts modules in our product. We need to install around 150+ sensors per house which are connected to one concentrator (master) device. Sensor are small and therefore using external antenna is not an option which may be problematic when using 169MHz? Those sensors are installed into houses with concrete walls and range requirements are therefore at least 150+ meters in NLOS situations. We are considering to use Wireless M-BUS protocol or some similar which do not require acknowledgements from the sensor. We prefer sub 1-GHz radio because of coverage. Could you suggest some of your modules which support 150+ slaves in one network and extended range at least 150+ meters in urban area? Please also take into account our antenna limitations. “
[W-MBUS] What is the range of Wireless M-Bus?
