Tool/software:
Is there any documentation/forum post/anything of that nature that goes into some more depth on using the proprietary radio for regulatory approval worldwide? To be more specific, I am looking for hints such as:
Using bands abc - xyz MHz at power level less than n dBm will be able to win you approval in 80% of the biggest economies.
Hi,
We have a vast experience of the regulatory approvals around the globe for sub-1 GHz ISM bands. If you have a 868/915 MHz design (one BOM and one design), this will cover a large amount of the biggest markets.
Summary of major markets:
Country | Frequency (MHz) |
Japan | 920-925 |
China | 470-510 or 868 |
USA | 902-928 |
Canada | 902-928 |
Mexico | 902-928 |
EU | 433 + 863-870 |
United State | 902-928 |
Thailand | 923-925 |
Singapore | 920-925 |
Philippines | 433 + 863-870 |
Vietnam | 920-925 |
Taiwan | 920-925 |
South Korea | 425 or 917-925 |
Brazil | 915-928 |
Malaysia | 920-925 |
Indonesia | 920-925 |
India | 865-867 |
Thank you for the update. Is there any TX power limit that are enforced in these countries?
Hi,
Generally, the "868 MHz" band follows the ETSI standard EN 300 220 which should not exceed 14.0 dBm of output power. The "868 MHz" band in China has a power restriction of 10 dBm.
- FYI, there is a 250 kHz window in the "868 MHz" band that does allow for 27 dBm.
Similarly, for the "915 MHz" band follows the FCC 15.247 standard which allows up to 30 dBm so output power is not restricted here for CC1312R.
Therefore, by making a design at 868/915 MHz with the CC1312R you will be able to cover most markets.
