Reply To: Stronger cell antenna?

Something to keep in mind is that our mobile phones have multiple radios and switch (mostly) seamlessly between different signals (3G, 4G, etc) but our XBee radios will only communicate on their designated protocol(s). Looks like the XBee 3 is LTE-M and NB-IoT and I don’t know anything about the latter.

This means that what we see on our mobiles is not always equivalent to what the XBees can use. So we have to dig a little deeper to know if the signals/protocols that our phones are using are accessible for the radio connected to your data logger.

(Thus we have reached the edge of my experience on this because I was able to ride on older radios through last summer.)
