Does anyone know the Wireless Frequencies allowed in India?

I am planning to purchase the “Industrial IoT RS485 To Wireless Converter”.

Does anyone know the wireless frequencies that are allowed in India so that I can purchase the correct one.

Thank you and regards.

India does not have an fixed restriction on either freq 900 or 868Mhz. You can use either one. Generally users go with 900Mhz.



Thank you for this information.
Is there any official documentation about the same?

Not that I don’t believe you but I would like to know it officially so that I don’t run into trouble with law enforcement.

Thank you and regards.
