Simplified Networking: SMOAD Multipath Cellular Aggregation in Action

Multipath Cellular Aggregation, as the name suggests, is the technique of combining multiple cellular connections to form a stronger and more reliable internet link. It is a modern network technology that helps organisations address connectivity challenges by creating high-bandwidth, resilient, and uninterrupted connections. Businesses that rely on remote or hybrid workers, as well as applications that demand high availability, can benefit immensely from Multipath Cellular Aggregation (MCA).
By consolidating multiple paths, MCA ensures that the overall network remains stable even when one or more connections face degradation or outage. This makes it a practical solution for enterprises that need to keep operations running smoothly at all times.

What is cellular bonding, and how does it work?
Cellular bonding is a process where multiple cellular data links are combined to work as a single, unified connection. Data is divided into smaller packets and transmitted simultaneously across available connections. On the receiving end, these packets are reassembled to maintain the integrity of the session.
Unlike traditional backup systems where one link sits idle until another fails, bonding ensures all available links work together in parallel. This not only maximises bandwidth but also provides redundancy and resilience. By using links from different carriers, businesses can protect themselves from network congestion, outages, and performance dips.

Key technologies enabling multipath aggregation
Several core technologies power multipath aggregation, making it a dependable solution:

1. Multipath TCP (MPTCP): An extension of the traditional TCP protocol that allows a single connection to operate across multiple paths simultaneously. It is widely supported by modern operating systems and is an important enabler for multipath aggregation in both 4G and 5G environments.
2. LTE Carrier Aggregation: A technique used at the radio layer where multiple LTE channels are combined, resulting in increased bandwidth and higher throughput.
3. Link Layer Bonding: Tools aggregate multiple physical interfaces into a single virtual interface, distributing traffic across all available links. A well-known example is the Linux Bonding Driver, which enables efficient link utilisation.

Multipath cellular aggregation and network resilience
Multipath Cellular Aggregation significantly enhances network resilience by intelligently distributing traffic and managing multiple connections. Its benefits include:

1. Automatic path switching: If a cellular link fails due to congestion, weak signal, or hardware malfunction, traffic is immediately redirected to another available path without disruption.
2. Zero manual intervention: Failover is automatic, removing the need for manual troubleshooting during outages.
3. Carrier diversity: Businesses can combine links from multiple carriers, protecting against provider-specific issues.
4. Multiple interfaces: Even if one physical interface fails, others continue to maintain the session.
5. Load balancing: Traffic is evenly distributed, preventing congestion on a single path and ensuring optimal use of available resources.
6. Dynamic path selection: Modern SD-WAN solutions monitor real-time conditions and choose the most efficient route for data transmission.
7. Multipath TCP advantage: Even single sessions can utilise multiple paths, ensuring continuity of applications even if one path fails.
8. Simultaneous connectivity: By connecting to multiple base stations or networks at the same time, the likelihood of a total outage is drastically reduced.
9. Reliable performance in remote locations: In areas with poor coverage, multiple aggregation ensures stable connectivity by pooling limited resources.
10. Business continuity: Mission-critical applications remain accessible, ensuring productivity is not impacted during disruptions.

Benefits of multipath cellular aggregation
The adoption of MCA brings several measurable benefits to organisations:

• Increased speed: Research shows that using four cellular interfaces can deliver up to 2.39 times the speed of a single interface.
• Reduced packet loss and latency: Carrier diversity and aggregation protect against connection drops and spikes, enabling a smoother experience.
• Support for demanding applications: Bandwidth-intensive or latency-sensitive workloads such as video conferencing, cloud access, and critical business operations perform significantly better.
• Cost savings: Multiple cellular connections can serve as an alternative to expensive leased lines, reducing operational costs while still delivering high availability.

Use cases of multipath cellular aggregation
The versatility of MCA makes it suitable for many industries and scenarios:

• Rural connectivity: In areas with limited coverage, relying on a single carrier often leads to unstable connections. Multipath aggregation improves reliability by combining whatever coverage is available.
• Business continuity: Enterprises can ensure uninterrupted application performance with SD-WAN powered by multipath aggregation.
• Temporary sites: Construction sites, outdoor events, and kiosks often require reliable internet on a temporary basis. MCA enables stable connectivity without relying on fixed-line infrastructure.
• Mobile operations: Logistics fleets, emergency services, and remote teams can remain connected at all times, even while on the move.

The role of 5G in cellular aggregation
Modern MCA devices can pool up to five frequency bands, greatly enhancing bandwidth availability. With the rollout of 5G, the benefits are even greater, as 5G devices can connect to multiple base stations simultaneously and aggregate resources for higher performance. This makes MCA an essential technology for businesses that require both speed and resilience.
By blending 4G and 5G connections, MCA allows organisations to prepare for the future of networking while still taking advantage of existing infrastructure.
