Imagine an emergency scenario where a first responder can treat or monitor an injured person in a remote location with guidance from a doctor via real-time video. The first responder is equipped with a backpack that not only contains essential medical supplies, but also a ruggedized laptop and a solid state software-defined wide-area network (SD-WAN) appliance that provides dual LTE connectivity to a 4G network.
This innovation known as backpack-as-a-service is possible thanks to SD-WANs, which now have many emerging use cases beyond just connecting branch offices, warehouses, and retail locations. SD-WANs are built for mobile environments to prioritize critical and real-time applications, such as video telemedicine.
