Enterprises deploying the Cisco 2811 Integrated Services Router (C2811-3G-S-SEC/K9) with HWIC-3G-CDMA-S, 128 MB Flash/512 MB DRAM and Advanced Security can establish encrypted VPN tunnels over 3G networks when fixed-line WAN links are unavailable. In a field office or retail outlet in a remote location, this configuration ensures continuous, PCI-compliant data transmission to headquarters, reduces downtime by 99.9%, and maintains enterprise-grade firewall, IPS and VPN protection without on-site IT staff.
Disaster-response units mount a Cisco 2811 (C2811-3G-S-SEC/K9) with HWIC-3G-CDMA-S, 128 MB Flash/512 MB DRAM and Advanced Security in vehicles to provide resilient, secure broadband connectivity in crisis zones. Real-time video surveillance, VoIP communications and GIS mapping run simultaneously over encrypted 3G links. The outcome is rapid situational awareness, hardened perimeter defense and guaranteed access to critical data feeds—even when terrestrial networks are down.
National retailers integrate the Cisco 2811 Integrated Services Router with HWIC-3G-CDMA-S, 128 MB Flash/512 MB DRAM and Advanced Security as an automatic failover appliance for point-of-sale terminals. In the event of primary DSL or cable outage, the router instantly switches to 3G-CDMA connectivity, keeping transactions flowing with end-to-end encryption and compliance to PCI-DSS. This reduces revenue loss by up to 100% during service interruptions and safeguards customer data.
