Important Notes
- Please handle the connectors with care as to not damage them.
- LTE-A (CAT-6) and LTE-A Pro (CAT-12) FlexModule Minis have 2x cellular antenna connectors while LTE-A Pro (CAT-18) and 5G have 4x cellular antenna connectors. So if you are upgrading from LTE-A (CAT-6) or LTE-A Pro (CAT-12) to either LTE-A Pro (CAT-18) or 5G, you will require additional antennas.
- FlexModule Minis are fully interchangeable with other FlexModule Minis, e.g. Ethernet, and cellular.
