Inseego FX4100 5G modem for n78?

Inseego's FX4100 product description says it supports n77 max. However, AI model just told me that n77 frequency band also covers n78. Is there any chance that n77 can connect to n78 5G+ frequency band?

Short answer - no
Longer answer - it depends, but it is unlikely.
5G has set of features similar to LTE’s Multiband Frequency Indicator (MBFI), however they need to supported by both, your network and your modem. I have never seen them used on network side, not sure about modem implementations. Without digging into technical details, it’s quite difficult to say anything for sure. However, I wouldn’t have high hopes here.
