Now that Wi-SUN technology and its applications have been explained, here is ROHM’s solution for Wi-SUN applications. This is the BP35C5 module which comes with a built-in Wi-SUN FAN software stack which reduces design development efforts. The BP35C5 is Wi-SUN certified and radio law certified by the Radio Act of Japan and the US; therefore, it can be used immediately. The BP35C5 comes in a module that is shielded for RF signals, making it more reliable and minimizing loss of communication. It can connect up to 100 units using only BP35C5 modules, increasing the coverage distance. It has very good obstacle resistance and provides fast communication, supporting selectable speeds of 50 kbps, 150 kbps, and 300 kbps. Additionally, there is no monthly running cost for the service.
