Portabella - 4G LTE, 5G Bonding

Fastest & most reliable mobile SD-WAN


Single 4G LTE/5G is too Fragile

Cellular wireless connections are susceptible to performance fluctuations and variations. 4G/5G connectivity can be unpredictable and unreliable, posing a critical risk for applications that demand uninterrupted Internet access. A single cellular link may not suffice for mission-critical operations that require consistent, high-performance connectivity.

Live Streaming Challenges with One Cell Modem

While 4G LTE and 5G cellular modems offer cost-effective and mobile alternatives to expensive satellite dishes, live webcasting or video streaming from remote locations over a single cellular modem is rarely seamless. The variability in single modem performance often leads to disruptions, hampering reliable live video delivery.

Bandwidth Limitations of Single SIM Cellular Device

Applications that demand high peak rates and substantial capacity, such as Wi-Fi hotspot services in mass transportation vehicles or special events, cannot be adequately supported by single SIM cellular MiFi devices. These scenarios require more robust bandwidth capabilities that exceed the limitations of a single cellular connection.

Not Adequate for Mission-Critical Use

Real-time, mission-critical applications cannot tolerate disconnections or failures. This issue is exacerbated in vehicular setups, where the movement of the vehicle can cause connectivity problems and application failures when relying solely on a single 4G LTE or 5G wireless network. Such mission-critical scenarios demand higher reliability and redundancy to ensure uninterrupted operations.


High-Speed Connectivity with 4G LTE & 5G Bonding

Discover the ultimate online experience with Portabella, our innovative Broadband Bonding™ appliance. Designed to unify and seamlessly manage multiple wireless SIM connections, Portabella offers you the flexibility to combine services from 2, 4, or even 8 different providers. Envision a world where your internet connection is not just faster, but supremely reliable, ensuring that every online session feels like a leap into the future, guaranteeing project success and delivering peace of mind.

Live Video Broadcasting & Webcasting

Elevate your live video and webcasting to new heights with Portabella. Harness the power of our Streamer add-on, engineered specifically for live transmissions. This sophisticated tool applies advanced coding to manage and optimize your streaming, guaranteeing that common network issues like packet loss, latency, or jitter become things of the past. With Portabella, step into a realm where your live videos are transmitted with crystal clarity and unmatched stability, minimizing disruptions and maximizing viewer engagement.


Bonded WAN Speed

Portabella is a cutting-edge packet-level load-balancing 4G LTE, 5G router that bonds multiple cellular Internet access lines for aggregated downlink and uplink capacity. When peered over the Internet with a Mushroom Relay at your headquarters or data center, Portabella seamlessly bonds all types of traffic, including encrypted VPN connections, delivering unparalleled bandwidth. Alternatively, the optional Broadband Bonding Service hosted by us enables downlink/uplink bonding for even greater throughput.

Seamless Live Video Streaming

Portabella’s free Streamer tunnel add-on optimizes live video streaming from the field to any CDN or video server over the bonded 4G LTE, 5G modems. This video-optimized bonding tunnel shields live video streaming applications from network issues like packet loss, latency, jitter, or even full modem disconnects, ensuring uninterrupted, glitch-free streaming even in the most challenging conditions.

Rugged and Versatile Design

Some Portabella models feature embedded modems with high temperature and vibration tolerances, including train certifications, for robust performance in demanding environments. Other models support external USB-based modem ports, offering flexible deployment options in a compact form factor.

Elastic Static IP

Portabella supports mapping static IP addresses from the cloud or your data center, enabling stable IP addressing for services like VPN, VoIP/SIP, and others. Inbound network access remains available even during 4G LTE or 5G outages, as long as one WAN link is connected, ensuring business continuity.

Zero-Touch Provisioning & Management

Portabellas are preconfigured before shipment, enabling zero-touch installation right out of the box. Additional configuration and monitoring can be done through the user-friendly web-based management interface locally or remotely, as well as through a cloud-based Portal providing in-depth monitoring capabilities. All wireless ISPs are supported worldwide.

Network Security & Scalability

Portabella can be configured in pass-through mode to function inline with existing legacy firewalls/routers, leaving your network configuration untouched. Alternatively, Portabella can act as the primary firewall/router, offering strong encryption (up to AES 256), website blocking, DNS redirection, and advanced filtering, all based on field-proven secure platforms, ensuring comprehensive network security and scalability.
