Symphony Link and LoRaWAN?
A revolutionary wireless system powering AirFinder.
Symphony Link is a wireless solution for enterprise and industrial customers who need to securely locate and monitor assets via the cloud with AirFinder. It’s the only LPWA system with:
Symphony Link grows with you. Expand network range using power-efficient repeaters without impacting latency.
Symphony Link manages frequencies, time slots, node privilege and throughput to insure QoS.
Symphony Link acknowledges all uplink and downlink messages to ensure successful transmission from devices.
Symphony Link economizes on resources by enabling patch security issue patches or new feature or bug fix management without physical, human attention.
WiFi and ZigBee ranges are too limiting, cellular is too expensive and power-hungry, and most LPWAN systems don’t have the features necessary for your application. Symphony Link is specifically designed for low power, wide-area network (LPWAN) applications that are easily scalable and perform with best-of-class reliability.
Guaranteed message receipt: Because Symphony Link acknowledges every message, you’ll know immediately if a message has been successfully transmitted from your device.
Real-time power and data rate control: Before every Symphony Link transmission, an end device calculates the reverse link to the gateway and adjusts its transmit power and modulation rate to match. This way, nodes throughout the network have a balanced link budget.
Multiple gateway coexistence: Symphony Link uses a dynamic channel mask controlled by the gateway, ensuring as few collisions as possible.
Bidirectional message acknowledgement: Symphony Link’s adaptive acknowledgement encoder allows nodes to transmit less frequently, which saves battery power and increases system reliability.
Interference avoidance: Up to 48 gateways (and their star networks) can coexist in the 915-MHz ISM band without affecting performance or adding redundant receive channels. This means adding a gateway truly increases capacity, unlike other LPWAN systems.
Extensible API: Symphony Link end users have the option of adding functionality directly into the gateway through an API, which allows for systems that receive a message from a local node to immediately process and generate a response without any internet connection.
Decentralized architecture: Symphony Link gateways perform a large portion of network processing locally, eliminating the need for a single, intensive processing server. This means gateways can continue performing most of their functions during a network outage or in a disconnected state, ensuring no data is lost once the network is running again.
Public key infrastructure (PKI): This over-the-air wireless channel used by Symphony Link is considered unbreakable by NSA standards, thus preventing spoofing and assuring the identity of the infrastructure.
Firmware over-the-air: The ability to patch vulnerabilities without physical device access lowers the cost, lowers the risk of deployment, and greatly improves security.
Real-time Advanced Encryption Standard (AES) key exchange.
Bank-grade Transport Level Security (TLS) for network traffic.
Repeaters: Expand the range of your Symphony Link network dramatically without impacting latency. Repeaters cost much less than an outdoor access point, allowing Symphony Link customers to cover larger areas without spending additional thousands on infrastructure. They are also power-efficient and can be solar- or battery-powered.
No per-device configuration: One of the biggest frustrations you can have when deploying a different LPWA network is managing multiple per-device encryption keys at the time of production and on the server side. With Symphony Link, the host device configuration is the same for all devices of the same type, and key exchange is handled via our world-class, PKI-based Diffie Hellman AES architecture.
Gateway roaming: With Symphony Link, nodes can easily roam from one gateway to another by scanning for availability. As your capacity grows, you can swap out small, single-channel gateways with high-capacity replacements.
Symphony Link is a highly scalable, low-cost alternative to tracking assets via cellular technology in a defined area.
