What is MultiWAN and Why Does It Matter?
MultiWAN is a technology that enables a router to utilize multiple internet connections (WAN) from different providers or through diverse communication channels simultaneously. Unlike the conventional approach, which relies on a single WAN interface, MultiWAN introduces redundancy and enhances network reliability. If one connection fails or becomes overloaded, traffic is automatically rerouted through alternative channels, ensuring uninterrupted internet access even in the event of an outage from the primary provider.
Key Benefits of MultiWAN
The primary advantage of MultiWAN is its resilience. By duplicating connection paths, it guarantees continuous uptime, which is crucial in environments where downtime is not an option. Additionally, MultiWAN optimizes load balancing across available channels. The router distributes data streams dynamically, selecting the least congested route for each request. This improves overall bandwidth efficiency, ensuring stable and high-speed performance even under heavy network loads.
Flexibility and Cost Efficiency
Another key advantage of MultiWAN is its flexibility in combining different types of connections for specific needs. For instance, a primary high-speed connection can be dedicated to critical services, while a lower-cost backup connection ensures failover reliability. In some cases, MultiWAN is also used for bandwidth aggregation, where multiple inexpensive connections are combined to achieve higher overall speeds. While individual link speeds remain unchanged, utilizing multiple internet lines in parallel can significantly enhance the total bandwidth available to all devices on the network.
This approach is especially useful in areas where a single high-capacity connection is not feasible. In the end, MultiWAN provides the best of both worlds — reliability through redundancy and enhanced bandwidth by pooling resources.
Blackbird by Chirp: MultiWAN in Action
Blackbird, a mining device developed by Chirp, is an advanced IoT gateway that integrates MultiWAN technology across multiple layers..
- Diverse Connectivity Options
Blackbird supports multiple internet access methods. It features an Ethernet port for wired connections, a built-in Wi-Fi module, and an LTE modem with a proprietary Chirp SIM card. These interfaces can operate simultaneously or serve as backups for each other. For instance, if the primary wired connection goes offline, Blackbird seamlessly switches to Wi-Fi. If both Ethernet and Wi-Fi fail, the device automatically connects via LTE, ensuring uninterrupted operation. This triple-layer connectivity (Ethernet + Wi-Fi + LTE) exemplifies the MultiWAN approach, significantly boosting device resilience in any scenario. - Multi-Standard IoT Communication
In addition to network redundancy, Blackbird supports multiple IoT communication standards. The device is equipped with LoRaWAN technology, operating in both sub-GHz and 2.4 GHz frequencies. This allows thousands of IoT devices to connect to the gateway without requiring separate infrastructure for each protocol. By consolidating multiple standards into a single device, Blackbird eliminates the fragmentation of IoT networks, streamlining connectivity for a broad range of applications.
Chirp: More Than Just a Network
It’s essential to understand that Chirp is not just an IoT network — it’s a full-fledged ecosystem that supports a variety of devices and use cases. Some technologies within the Chirp ecosystem can function independently of Blackbird. For example, a smart door sensor can send a signal via the Chirp network, triggering an alert or activating a siren over Wi-Fi. While Chirp does not directly manage Wi-Fi devices, its ecosystem accommodates various types of integrations, enabling seamless interaction between different technologies. This unified approach positions Chirp as a versatile platform for creating an intelligent IoT infrastructure.
The Advantages of Blackbird
All-in-One Solution
Unlike traditional routers, which typically reserve MultiWAN functionality for enterprise-grade equipment in offices or data centers, Blackbird integrates multiple WAN options natively with automatic switching. Consumer routers with dual WAN ports are rare and often require manual configuration. In contrast, Blackbird’s built-in MultiWAN capabilities work out of the box, eliminating the need for complex setup. Additionally, while standard routers lack IoT compatibility, Blackbird combines professional MultiWAN routing with IoT gateway functionality, offering LoRaWAN support right from the start.
Helium and Other Networks vs. Chirp Blackbird
Decentralized wireless networks like Helium primarily focus on LoRaWAN connectivity. However, Helium hotspots operate on a single frequency band and a single protocol, limiting their application. If an IoT device does not support LoRaWAN, it cannot connect to Helium. Blackbird, on the other hand, offers a multi-protocol environment, expanding compatibility beyond a single standard and providing users with more flexibility.
Conclusion
Chirp Blackbird showcases how a well-integrated combination of MultiWAN technology and IoT connectivity can revolutionize IoT infrastructure. With its resilience, failover protection, and flexibility, Blackbird replaces multiple specialized devices with a single, powerful solution. At the same time, Chirp extends beyond a single product, fostering an ecosystem where diverse IoT solutions interact seamlessly. This is a step toward a scalable, reliable, and accessible IoT network, where cutting-edge technology enhances connectivity for a broad range of users.
