Selection Notes
The dual SMA antenna sockets with MIMO reception and support for LTE, UMTS, and GSM make this the cellular variant for a site with no wired Ethernet or PROFIBUS backhaul; it reaches the network over mobile radio instead. Its EN 50121-3-2 and EN 50121-4 railway EMC approvals suit trackside or vehicle-mounted control cabinets, not just fixed industrial panels, where an uncertified cellular router would fail acceptance testing.
