- I am trying to interface my STM32 with NRF24[2.4 Ghz ] or TI CC2500[2.4 Ghz] models. I am finding issue regarding maximum allowable Bandwidth and RF power set by ETSI[Europe] EN 300 328 and EN 300 440(Short Range Devices[SRD]) regularity body. Kindly if someone have knowledge regarding this please share it. I am unable to find relevant info I have even consulted ETSI Official Documents but of no avail.
- Can I even use 12Mbps speed if I use cc2538 SOC.
- What is better to use a RF Transceiver (TI CC2500) or SOC RF Module (TI CC2545 or TI CC2538).
I'm not saying EN300328 (Electromagnetic compatibility and Radio spectrum Matters (ERM); Wideband transmission systems; Data transmission equipment operating in the 2,4 GHz ISM band and using wide band modulation techniques; Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive) is the document you need because your question is lacking in detail but this is a good example of 2.4 GHz transmission power and bandwidth requirements: -
Regards your other questions, you will have to read the data sheet for the devices yourself to ascertain what maximum data rates they can run at and, "which one is better?" - what does "better" mean in this context: -
- Easier to set-up?
- More power efficient?
The list could go on!
