Other Parts Discussed in Thread: WMBUS

How Symbol rate related to carrier frequency, Like in smart RF stdio at 869 MHz max throughout 200 Kbps, and in 169 Mhz max throughout is only 9.2 kbps.

Please clarify.

can it is possible to achieve 200 kbps in 169 MHz also.

    The symbol rate is not linked to the carrier frequency.

    You can take the settings for 868 MHz and get them to run on 169 MHz by changing the frequency. The reason we only have low datarate settings for 169 MHz is that we have mainly tested WMBUS N mode on this band.

    Have you checked the regulations for your location that 169 MHz can be used for this datarate?
