CISCO881G-G-K9 Use Case
Secure Remote Branch Connectivity with 3G Failover
In a multi-site enterprise, the CISCO881G-G-K9 FE Sec Router with Advanced IP Services and 3G GSM/HSPA provides primary VPN connectivity over DSL or Ethernet and automatic 3G failover in case of WAN outage. This ensures uninterrupted site-to-site encrypted communication, minimizes downtime, and preserves business continuity for critical applications such as ERP and VoIP.
Industrial IoT Edge Gateway with Built-In Security
A manufacturing plant deploys the CISCO881G-G-K9 as an IoT edge gateway to aggregate sensor data over Gigabit Ethernet and deliver it securely to cloud analytics via 3G backup link. Advanced firewall, IPS, and NAT features protect OT networks from external threats, while continuous connectivity enables real-time monitoring, predictive maintenance, and improved operational efficiency.
Retail Point-of-Sale Resilience During Network Outages
A retail chain uses the CISCO881G-G-K9 to secure and accelerate payment transactions across hundreds of stores. The router’s Advanced IP Services optimize WAN performance, and its integrated 3G HSPA modem automatically switches over during primary link failures. This guarantees PCI-compliant secure payments, reduces abandoned carts, and sustains revenue even when the main network is down.
