Portabella - 3G 4G 5G LTE Bonding

Fastest & most reliable mobile Internet

3G 4G LTE 5G Challenges

Single 3G/4G/LTE/5G is too fragile

Cellular connections are prone to fluctuations and variations in performance by their very nature. No matter which carrier it is, connectivity will be unpredictable and unreliable at times. This can be deadly for applications that require uninterrupted Internet connectivity.

Live video streaming is hard with one modem

3G, 4G, LTE, 5G cellular modems are great alternatives for more expensive satellite dishes, with lower cost and enhanced mobility. However, live webcasting or live video streaming from the field over a single cellular modem is rarely successful because of the variability of single modem performance.

Not enough bandwidth

Sustaining high enough rates for applications that require high throughput, such as hotspot services in mass transportation vehicles or special events, is not possible with only one cellular modem.

Low reliability for mission-critical applications

Certain real-time applications are mission critical and cannot afford to have disconnections. This problem is increased in vehicular setups, where the moving vehicle will cause connectivity problems and application failures when implemented using a single 3G, 4G, LTE, or 5G wireless network.

The Solution

Portabella is a packet-level load balancing 3G 4G LTE bonding router

3G/4G/LTE/5G Bonding

Portabella is a Broadband Bonding™ appliance that combines and intelligently manages 2, 4 or 8 cellular SIM connections from any of your service providers. Portabella can stripe a single session over the available paths and therefore create a single super-fast pipe by using our cloud relay service.

Live Video Broadcasting & Webcasting

Portabella supports a bonding tunnel that is optimized for live video transmission using our Streamer add-on. Streamer applies a special coding before transmitting partial streams and therefore any network problems such as packet loss, latency or jitter can be shielded from the video application.


Bonded WAN Speed

Portabella is a packet-level load-balancing 3G/4G/LTE/5G router. Portabella can bond cellular Internet access lines for all types of traffic (including encrypted traffic such as VPN) for aggregated downlink and uplink capacity when peered over the Internet with a Mushroom Relay located at the headquarter office or data center. The optional Broadband Bonding Service subscription enables downlink/uplink bonding.

Without peering, all HTTP downlink sessions are still bonded for faster file transfers. Even in cases of single HTTP session (such as a single file download), all Internet access lines are simultaneously and intelligently combined together to provide a faster data transfer for that single session.

Without the optional peering, non-HTTP downlink sessions and all uplink sessions initiated from the local network, will be session-based load balanced intelligently across the 3G, 4G, LTE, or 5G WAN lines. The application and cookie semantics will be preserved for sites such as banking sites.

Live Video Streaming

Portabella supports a free add-on tunnel (Streamer) that is optimized for live video streaming from the field to any CDN or video server over the bonded 3G, 4G, LTE, 5G modems. This video-optimized bonding tunnel enables live video streaming applications to be 100% shielded from any network problems such as packet loss, latency, jitter, or even full modem disconnects. Even during those situations, your live video stream will continue without a glitch.

Network Security & Scalability

Portabella can be configured in pass-through mode to function inline with the existing legacy firewalls/routers with the existing network configuration untouched. If preferred, Portabella can also be installed as the primary firewall/router with strong encryption (up to AES 256), website blocking, DNS redirection, and advanced filtering, all based on field-proven secure platforms.

Elastic Static IP

Static IP addresses in the cloud (or from your data-center) can be mapped onto the Portabella. This means that static IP is available for services that rely on stable IP addressing, such as VPN, VoIP/SIP and others. Inbound network access remains available, even during 3G, 4G, LTE or 5G outages, as long as at least one of the WAN links is connected.

Ruggedized Design

Various Portabella models support embedded modems with high temperature and vibration tolerances, including train certifications. Other Portabella models support external USB-based modem ports for additional flexibility.

Zero-Touch Install & Management

Portabellas are preconfigured before shipment and therefore supports zero-touch installation when received. Any additional configuration or monitoring can be done through the web-based management interface either locally or remotely, as well as through a cloud based Monitoring Portal that provides in-depth monitoring capabilities. All wireless ISPs are supported worldwide.
