USA, South America & Australia, Symphony Link

The LL-RLP-20, or LL-RXR-27 module participates as an endpoint with compatible Symphony Link networks. The module automatically connects to an in-range Symphony Link gateway. The gateway relays uplink messages from the module to Conductor, Link Labs’ cloud-based data services platform. Likewise, the gateway relays downlink messages sent from Conductor to individually addressed modules.

• Well suited for high-capacity applications.
• Implements a star network based on a slotted Aloha scheme.
• Network operation controlled by handshaking between module and gateway.

The LL-RLP-20 module can be designated as a endpoint, repeater or gateway node. The gateway node constantly monitors an uplink channel to catch uplink messages sent from endpoints. The protocol is bi-directional and a gateway node can send downlink traffic to individually addressed endpoints via a downlink mailbox. The system also implements repeater nodes to extend the range of the network - one repeater maximum between each endpoint and gateway.

• Orchestrates a pure Aloha star network.
• Well suited for low-cost, low-capacity applications.
• A gateway node can be battery powered.

Private Networks Applications

4 x LL-RLP-20-USB-A (USB evaluation boards that have the Link Labs module embedded.)

4 protocols in the one module. Ideal Proof of Concept package. You can use 3 boards as end nodes attached to sensors. The other board can be put into gateway mode and used to collect data.

Public Network Applications

8 channel indoor gateway with WiFi connection. 3 x LL-RLP-20-USB-A  plus an LL-BST-8-868-LRW-W-I-EU.

In this case you can select the USB boards in LORAWAN mode and communicate via the gateway to the cloud using Link-Labs cloud server, Conductor.
