Broadband Bonding & SD-WAN Solutions for Enhanced Transportation Connectivity

Providing Internet for moving vehicles such as trains, buses, and other mass transportation vehicles, as well as specialty vehicles like ambulances, fire trucks, and police cars, is challenging. Portabella is used to provide Internet access for passengers, connectivity for mission-critical systems within the vehicle, and IP connectivity for the Internet-of-Things (IoT) sensors on board.


Moving vehicles must rely on wireless Internet. Although 4G LTE and 5G networks have been widely deployed and provide high levels of coverage, they suffer from fluctuations in performance depending on the coverage area and even time of day. Mobility or cell congestion caused by overloaded users in a particular area can add to the challenge. The unpredictable performance of a single 4G LTE or 5G connection is simply not adequate for the job and cannot support mission-critical applications.

Mushroom Networks’ Portabella delivers reliable and fast Internet for vehicles on the go by broadband bonding two or more 4G LTE or 5G modems together to enable better performance and higher reliability. Portabella is an SD-WAN Broadband Bonding appliance that can house two or more (up to eight, depending on the model) cellular 4G LTE or 5G modems (or SIM cards) and merge them into a single fat and reliable IP pipe.

Portabella is ideal for trains, buses, ships, fire trucks, ambulances, first responders, law enforcement vehicles, and other specialty vehicles and teams. Portabella’s ruggedized design allows deployments in harsh and challenging environments.

Multiple Active SIMs for Increased Reliability

By intelligently aggregating multiple cellular modems from the same or differing providers, the resulting Internet connectivity becomes much more robust, resilient, and high-performance than a single cellular connection. Live video or other real-time, mission-critical applications can leverage the aggregate throughput, avoid packet loss, and perform at a level not attainable with a single modem.

Zero-Touch Configuration for Seamless Deployment

Portabella appliances are ideal for taking over the burden of network management for on-board vehicle applications. Zero-touch installation ensures that they connect instantly and seamlessly to the Internet while optimizing critical Internet applications. The router automatically manages the connectivities of the cell modems for optimum performance.

Centralized Monitoring for Efficient Management

The optional Monitoring Portal provides a single-pane dashboard for all registered devices and enables single-click remote access to each device when needed. Various telemetry and network statistics are stored in the Monitoring Portal, giving IT managers a comprehensive and actionable view of their network.


Mushroom Networks’ Portabella appliances enable applications such as live video streaming from an ambulance or providing WiFi Internet access to train passengers. Portabella multi-SIM routers are capable of adapting to the changing channel conditions of cellular connections to automatically optimize application performance. When application uptime and performance are important, the best-of-breed SD-WAN and broadband bonding solutions from Mushroom Networks are ready for the job.

Single 4G LTE or 5G networks inevitably have fluctuations in performance. Portabella is a cellular bonding device that can combine multiple cellular SIM cards from any carrier into a fast and robust Internet connection optimized for various application classes, including live video streaming, mission-critical IoT applications, or best-effort data.


“Due to Mushroom Networks’ cutting-edge technology, we can now use laptop sim cards and bond them together to create an incredibly fast connection for the entire bus. Because Portabella allows us to utilize mobile broadband services from multiple carriers, we rarely lose connection even in rural areas or if one card goes down.”
