State-of-the-art LoRaWAN® Network Server

MAC Layer Management

• RF macro diversity, i.e., ability to route the device's uplink packets through multiple gateways.

• Uplink frame deduplication (macro-diversity, device repetitions...): Ensures that uplink frames received by multiple Base Stations will be notified only once to the application servers.

• Advanced ADR mechanisms, offering the best trade-off between QoS (packet error rate, RF overlapping) and device's power consumption, to maximize its battery lifetime and reduce TCO.

• LoRaWAN® MAC commands, including optimized retransmission mechanisms: learning algorithm to optimize the retransmission of MAC commands that are either not answered or rejected by the device.

• Smart selection of the best gateway to route downlink packets to each device.

• Optimum selection of the device's downlink receive window (RX1/RX2) via RX2 Optimization algorithm, based on link budget, downlink capacity and backhaul latency.

• Multiple RX2 and pingslot channels per gateway, offering RF channel load balancing.

• Queuing of applicative downlink frames for class A devices.

• MAC-level acknowledgments.

• Replay attack detection and mitigation.

Best in class self-organizing Adaptive Data Rate (ADR)

• Dynamically adapt the device's transmission parameters (TxPower, number of transmissions, data rate) according to the quality of the device-gateway radio link.

• Minimize the device's battery consumption while fulfilling the target quality metrics (especially the uplink packet error rate).

• Adjust its reactivity to avoid too volatile decisions (increasing signaling overhead induced by MAC commands) or slow response to abrupt RF changes (e.g. the nearest GW to the device goes down).

• Adaptation of the ADR algorithm according to the mobility type of each serving gateway.

• Automatic adaptation of overlap criterion according to the dynamic network geolocation mode (TDoA or RSSI).

Value-added services

• Embedded Join Server function, providing a local processing of OTA activation requests, in absence of a standalone Join Server.

• Passive Roaming, using both v1.0 and v1.1 of the LoRaWAN® Backend Interfaces standard.

• Multicast, optimizing downlink spectral efficiency to support firmware upgrade over the air (FUOTA) and smart lighting use-cases.

• Network-based geolocation, using sophisticated field-proven triangulation algorithms leveraging the best of TDoA & RSSI geolocation techniques.

Operability

• Multi-tenant traffic segregation: isolating LoRaWAN® traffic between different tenants, i.e. uplink packets for network-B cannot be routed through network-A's RAN except in case of roaming agreement.

• Remote gateway configuration: online update of the gateway's RF configuration (channel plan, antenna gain...) as well as remote maintenance.

• Support for all LoRaWAN® NetID types, including blocks of type-7 NetIDs for non LoRa-Alliance members. NetID subnetting is also supported by ThingPark.

Comprehensive reporting

• Uplink Frame Report: uplink payload with rich set of metadata and decoded payloads.

• Downlink Frame Sent Report: Notify Application Servers about the transmission status of each DL message, including failure cause (radio congestion, duty cycle constraint...).

• Device Notification events: in case of JOIN event, reporting of device's battery status...

• Location Reports (if Network Geolocation feature is activated).

• Multicast Summary Reports.
