Hi, regardless of location and local regulations which one of the RFD modems is actually better? There are 868Mhz and 900Mhz versions. And let’s talk about unlocked modems - those without the country suffix, so only RDF900x and RFD868x.
Which one of these will get you a better range and performance?
One would say, the lower the frequency the better the range but the lower frequency one also has fewer channels to choose from.
