The mode to use depends on the desired system solution. For water and gas meters often deployed in pits or basements, mode N is preferred due to the long range. For shorter distance (in house/building), walk-by or drive-by systems mode T and C is preferred.

Wireless M-Bus Q&A Related Knowledge Base Posts - [W-MBUS] “I configured the MBUS radio to use the UART flow control using the CTS/RTS pins. When the host processor wants to send an MBUS message, it pulls the RTS pin low and waits for the radio to pull CTS up. The processor then sends the message. But this gives strange results, and sometimes it just fails to send the message. I also tried using only the CTS pin, where I wait for the pin to go high before sending the message. Again, this does not always work. Are the CTS/RTS pins exclusively for controlling the flow over the uart connection (host processor to radio) or are they meant to indicate when the radio can send another message ? If so, how should I use them ? “ [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] “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. “
