- [W-MBUS] “Regarding the modulation, I have a question about setting the modulation method. In my measurements , I changed the RF frequency with the volatile ‘C’ command. There is no volatile command to change the modulation method, so I left it at default. Then I find that the message transmission time at RF is the same for all channels, suggesting that the modulation scheme is the same. Is this the case, and is the default modulation valid for all channels? I need not be compatible with strict EN 13757. “
- [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. “
