Multi-SIM Broadband Bonding Solutions for Enhanced Emergency Response Connectivity

Emergency response presents one of the most challenging environments for maintaining high-performing and reliable wireless Internet connectivity at emergency locations or from first responder vehicles. State-of-the-art multi-SIM broadband bonding solutions from Mushroom Networks provide the ultimate Internet connectivity, enabling emergency response teams to have the utmost situational awareness, ultimately saving lives.


Emergency response is currently undergoing a major shift as the US and the rest of the world continue to build out the Next Generation 9-1-1 (NG911) system. NG911 allows callers, emergency dispatchers, and responders to share voice, images, videos, and other data across the 911 system, enabling Public Safety Answering Points (PSAPs) or Emergency Communication Centers (ECCs) to better manage emergencies and quickly dispatch the right resources.

This new paradigm places high demands on Internet connectivity to allow massive amounts of high-bandwidth, low-latency traffic to flow seamlessly between all connecting nodes of the public safety 911 system. Lost or delayed internet packets, which routinely happen on public WANs, can have dire consequences. Best practices require multiple, redundant connectivity routes that can intelligently manage and prioritize all types of traffic, monitor real-time line conditions for each WAN link, and immediately adjust and optimize the network connection in real-time for various applications.

5G and dedicated wireless networks exclusively reserved for public safety, such as AT&T FirstNet and Verizon Frontline, will significantly help implement NG911. However, the unpredictability of emergency locations means that LTE and 5G network performance will also be unpredictable. Broadband bonding technology that intelligently combines several wireless SIM cards creates a more predictable and higher-performance connectivity solution for emergency response teams on the go.


One of the most difficult challenges facing the NG911 program is obtaining a live video feed directly from the emergency site to the PSAP or ECC. Often, emergency locations lack easy access to wired Internet, necessitating the use of wireless cellular connectivity. However, a singular wireless connection is subject to performance fluctuations, lost packets, and even dropped connections. By leveraging broadband bonding and aggregation, it is now possible to intelligently combine multiple cellular modems (from the same or different ISPs) to create a single high-bandwidth, high-reliability broadband pipe optimized for live video streaming.

Optimized for Live Video Streaming

With broadband bonding, all LTE/5G cellular modems are aggregated to create a single fast and reliable Internet connection. Encoded video packets pass through a special overlay tunnel that protects against lost packets, latency, and jitter, shielding the video flow from network fluctuations.

Zero-Touch Configuration for Seamless Deployment

Portabella multi-SIM broadband bonding appliances are ideal for taking over the burden of network management for emergency response. Zero-touch installation ensures seamless and rapid deployment across the emergency response network, with remote access to devices from a Command and Control Center (CC&C).

Networks on Autopilot for Optimal Performance

Mushroom Networks’ dual-SIM and multi-SIM devices leverage overlay tunnels that automatically adapt to cellular channel conditions and application QoS requirements. This translates to a self-learning and self-adapting Internet connectivity solution that provides the best application performance for emergency response teams.
