What is LoRaWAN? Why is a Network Server (NS) Essential?

News / By /

As IoT deployment accelerates across industries, LoRaWAN has become one of the most important LPWAN standards. However, many engineers underestimate the importance of the LoRaWAN Network Server (NS) — the brain of any LoRaWAN system.

This article outlines the LoRaWAN architecture and explains the irreplaceable role of the NS.

1. LoRa ≠ LoRaWAN

  • LoRa is a physical layer modulation technology developed by Semtech.
  • LoRaWAN is an open communication protocol based on LoRa, maintained by the LoRa Alliance, covering device-to-server interactions.

2. LoRaWAN System Architecture

A complete LoRaWAN stack includes:

  1. End Devices – sensors or controllers collecting field data
  2. Gateways – bridging LoRa and IP networks
  3. Network Server (NS) – managing devices, deduplication, security
  4. Application Server (AS) – handling business logic and visualization

3. Why the NS is Indispensable

The Network Server handles:

  • Data deduplication when multiple gateways receive the same packet
  • MAC command handling for ADR, confirmations, device classes
  • Join process and encryption via integration with Join Server
  • Device management and message routing

Without the NS, you lose critical LoRaWAN features.

4. What Happens Without a Network Server?

  • No multi-gateway collaboration
  • No adaptive data rate
  • No payload encryption/decryption
  • Poor device tracking and scalability

Manthink’s ThinkLink Network Server offers:

  • Free and commercial versions
  • Cloud and private deployment options
  • Supports major LoRaWAN bands (CN470, EU868, AS923)
  • Easy integration with LoRa sensors and gateways

Ideal for smart agriculture, logistics, energy, and more.
