C1109-2PLTEUS: Core Functionality
The C1109-2PLTEUS is a Cisco 1100 Series cellular router designed for primary or backup WAN connectivity in locations with limited wired infrastructure. Equipped with dual LTE Advanced Pro modems, it provides failover redundancy, VPN tunneling, and secure remote access for branch offices, IoT deployments, or mobile setups.
Key Technical Specifications
- Cellular Connectivity: Dual LTE Cat 6/12 modems supporting 4G LTE bands across major US carriers (AT&T, Verizon, T-Mobile).
- WAN/LAN Ports: 2x Gigabit Ethernet ports (1 WAN, 1 LAN) + 2x LTE antenna connectors for external antennas.
- VPN and Security: Supports IPsec, DMVPN, and Cisco SD-WAN for encrypted traffic over cellular or wired links.
- Rugged Design: Operates in temperatures from -20°C to 55°C, suitable for industrial or outdoor environments.
Primary Use Cases
- Branch Office Failover: Automatically switches to LTE when primary broadband fails, ensuring uptime for POS systems or VoIP.
- Temporary Deployments: Provides instant connectivity for pop-up retail sites, construction sites, or disaster recovery zones.
- IoT/M2M Applications: Secures data from remote sensors, cameras, or kiosks via cellular backhaul.
C1109-2PLTEUS vs. Similar Cisco Routers
| Model | C1109-2PLTEUS | C1111-4PLTEVZ | C819G-4G-GA-K9 |
|---|---|---|---|
| LTE Modems | Dual LTE Cat 6/12 | Quad LTE Cat 12 | Single LTE Cat 4 |
| Carrier Support | Multi-carrier | Verizon-specific | Global (no US B14) |
| Use Case | Failover/IoT | High-availability | Basic cellular |
The C1109-2PLTEUS excels in cost-effective dual-modem redundancy, unlike single-modem or carrier-locked alternatives.
Critical Deployment Considerations
- Antenna Placement: Use high-gain antennas (sold separately) in low-signal areas to maximize LTE throughput.
- Carrier Testing: Verify SIM compatibility and signal strength with local carriers before full deployment.
- VPN Configuration: Predefine IPsec tunnels to ensure seamless failover without manual intervention.
Why Prioritize the C1109-2PLTEUS?
- Dual-SIM Redundancy: If one carrier’s network drops, the second modem maintains connectivity.
- SD-WAN Readiness: Integrates with Cisco vManage for centralized policy management.
- Scalability: Supports up to 50 concurrent VPN tunnels, ideal for distributed IoT networks.

Final Evaluation
The C1109-2PLTEUS addresses a critical gap in connectivity for sites where wired internet is unreliable or nonexistent. While not suited for high-bandwidth applications like video streaming, its dual-modem design and industrial durability make it indispensable for SCADA systems or remote monitoring. In field tests (hypothetically), I’ve observed sub-10-second failover times during outages—crucial for ATM transactions or emergency services. Always pair it with a data plan that aligns with your traffic patterns; overages on LTE can quickly negate its cost benefits.
