Broadband Bonding & SD-WAN Solutions for Transportation

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


Moving vehicles must rely on wireless Internet. Although 4G LTE, 5G networks have been widely deployed and are providing 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 therefore 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, 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 model) cellular 4G LTE, 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 or other specialty vehicles and teams. Portabella’s ruggedized design allows deployments for harsh and challenging environments.

Multiple Active SIMs

By intelligently aggregating together 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

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. Connectivities of the cell modems are automatically managed by the router for optimum performance.

Centralized Monitoring

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


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 the cellular connections to optimize application performance automatically. If application uptime and performance is important, the best of breed SD-WAN and broadband bonding solutions from Mushroom Networks is ready for the job.

Single 4G LTE, 5G networks unavoidably have fluctuations in performance. Portabella is a cellular bonding device that can take multiple cellular SIM cards from any carrier and combine them into a fast and robust Internet connection that is 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.”
