Cisco EHWIC-4G-LTE-ST Wireless WAN Interface Card is a cellular 4G LTE module designed to slot into Cisco EHWIC-compatible routers to add wireless WAN capability. It enables LTE network connectivity for remote sites or mobile deployments where wired broadband is unavailable, providing an additional WAN path. This EHWIC card is installed in the router's EHWIC slot and allows data traffic to traverse the LTE network alongside existing interfaces.
