Introduction
An ISR router with LTE (Long-Term Evolution) functionality integrates LTE capabilities into the traditional features of a Cisco Integrated Services Router (ISR). This integration enables the router to connect to cellular networks, providing an alternative or backup connectivity option when traditional wired connections are unavailable, unreliable, or too expensive to deploy.
Description
Cellular Connectivity: The router includes a built-in LTE modem and antennas, allowing it to establish a connection to LTE networks operated by mobile carriers. This cellular connectivity provides a reliable and high-speed data link, enabling the router to access the internet or connect to corporate networks even in remote locations or during network outages.
Primary or Backup Connectivity: Depending on the deployment scenario, an ISR router with LTE function can serve as either the primary or backup connection method. In primary mode, the router uses LTE as the main connection to the internet or corporate network, offering flexibility and cost savings, especially in locations where wired broadband options are limited. In backup mode, LTE serves as a failover mechanism, automatically activating when the primary connection (e.g., DSL, cable, fiber) experiences an outage or degradation in performance.
High Availability and Resilience: By leveraging LTE as a backup connection, businesses can enhance network resilience and ensure continuous operation even in the face of connectivity issues or disasters. The router can detect link failures on the primary connection and seamlessly switch traffic to the LTE connection, minimizing downtime and maintaining productivity.
Advanced Networking Features: An ISR router with LTE function inherits all the advanced networking features of traditional ISR models, including routing, switching, security, and management capabilities. This means it can perform tasks such as packet routing, firewalling, VPN (Virtual Private Network) termination, Quality of Service (QoS) management, and application optimization, ensuring the security and efficiency of data traffic over both wired and wireless connections.
Remote/Branch Office Connectivity: ISR routers with LTE function are particularly well-suited for remote or branch office deployments where wired connectivity may be costly or impractical. These routers enable businesses to quickly establish network connections in temporary or mobile locations, such as construction sites, pop-up stores, or disaster recovery sites, without the need for extensive infrastructure investment.
Overall, an ISR router with LTE function provides a versatile and resilient networking solution, combining the reliability and performance of traditional ISR routers with the flexibility and mobility of LTE cellular connectivity. It offers businesses a cost-effective way to ensure continuous connectivity and maintain productivity in diverse deployment scenarios.
A Cisco C899G-LTE-GA-K9 Integrated Service Router (ISR) has been used for this guide.
