Field-installable embedded LTE-A Cat-12 cellular modem for the Balance 580X HW2 FlexModule Mini bayThe right cellular module when 5G isn't justifiedThe Peplink FlexModule Mini LTEA Cat-12 is a hot-swappable cellular module that drops into the FlexModule Mini bay on the Balance 580X HW2 (and other compatible Peplink hardware with a Mini bay). LTE-Advanced Cat-12 modem with 600 Mbps theoretical downlink across 3-carrier aggregation; in real-world UK 4G mid-band coverage that translates to 200-400 Mbps consistent throughput. The right call for sites where 5G isn't deployed locally, 5G coverage is unreliable, or the cellular path is for failover only and Cat-12 is sufficient.
