Sim card based solutions

1
SD-WAN : SD-WAN is a software-defined approach to managing a wide area network (WAN), offering flexibility and control over how network traffic is routed and optimized.
2
SIM-based : In a SIM-based SD-WAN, the cellular network, accessed through a SIM card, is integrated as one of the transport options within the SD-WAN architecture.

Advantages: This integration allows businesses to:
• Leverage cellular connectivity in areas where traditional broadband or MPLS connections are unavailable or expensive.
• Achieve cost savings by reducing reliance on costly MPLS connections.
• Increase network resilience and availability by using cellular connections as a backup or primary path when other connections are unavailable.
• Simplify network management by centrally managing all WAN connections, including cellular ones
SD-WAN Controller
A central SD-WAN controller manages the entire network, including cellular connections.
Edge Devices
SD-WAN edge devices (routers or appliances) at different branch offices or locations have SIM card slots to connect to the cellular network.
Path Selection
The SD-WAN controller dynamically selects the best path for network traffic based on factors like bandwidth, latency, and cost.
Traffic Routing
Network traffic is routed through the chosen path, which may include a combination of cellular, broadband, or MPLS connections.
. Centralized Management
The SD-WAN controller provides a single pane of glass for managing all WAN connections, including cellular ones.
