Technology

LoRa technology is a proprietary wireless technology developed by Semtech Corporation. It utilizes a spread spectrum modulation in the Sub-GHz band to enable long range (greater than 10 miles) coverage, low power consumption (up to 10 years battery power), high network capacity (up to 1 million nodes), robust communication, and localization capability.

  • LoRa technology is capable of demodulating 20 dB below noise level, significantly improving immunity to the interference when combined with integrated forward error correction.
  • LoRa technology has high sensitivity, -148 dBm, enabling extremely long range connectivity.

LoRaWAN protocol

The LoRaWAN protocol is a Low Power Wide Area Network (LPWAN) specification intended for wireless battery-operated devices in regional, national or global networks.

LoRaWAN protocol targets key requirements of the Internet of Things such as:

  • Secure bi-directional communication
  • Mobility
  • Localization services

The LoRaWAN protocol standard will provide seamless interoperability among Smart ‘things’ without the need for complex local installations, further enabling the Internet of Things.

LoRaWAN Protocol Security

The LoRaWAN protocol implements several layers of encryption to ensure the highest security for the whole infrastructure.

  • Unique Network session key ensures security on Network Server/Network level
  • Unique Application session key ensures security on the Application Server/Application level
  • Application key specific for the end-device

The LoRaWAN protocol addresses a variety of applications by providing different protocol classes:

  • Bi-directional end-devices (Class A): End-devices of Class A allow for bi-directional communications whereby each end-device's uplink transmission is followed by two short downlink receive windows.
  • Bi-directional end-devices with scheduled receive slots (Class B): In addition to the Class A random receive windows, Class B devices open extra receive windows at scheduled times (available in future release)
  • Bi-directional end-devices with maximal receive slots (Class C): End-devices of Class C have nearly continuously open receive windows, only closed when transmitting (available in future release)

Infrastructure

LoRa Technology Infrastructure

LoRa technology network’s architecture is a star topology. End devices transfer data to gateways which pass data to the network server.

Currently there are two LoRa technology network options available:

1. Private network

  • Individually managed networks
  • Local area networks

The LoRa Technology private network is comprised of 3 basic parts:

  1. Microchip end-devices
  2. LoRa technology gateway
  3. LoRa technology network server

Microchip makes it easy to establish the LoRa technology IoT infrastructure by providing complete, fully-certified, LoRat technology end-device modules. The modules have embedded LoRaWAN on-board to easily connect to any LoRa Alliance certified gateway and network services listed below:

  • Gateway: Actility, Cisco, Kirlink, Multitech
  • Network Server: Actility, IBM, Senet

2. Public network

  • Telecom- and operator-managed networks
  • Nationwide deployment

The LoRa technology public network is comprised of 4 basic parts:

  1. Microchip end-devices
  2. LoRa technology gateway
  3. LoRa technology public network operator (Telecom)
  4. LoRa technology network server

Telecom companies integrate gateways on towers and provide network service. Microchip end-devices are embedded with the LoRaWAN protocol to easily connect to the Telecom service provider.

LoRa technology public service providers:

  • Europe: Bouygues, KPN, Vodafone, Swisscom
  • Asia: SingTel
