LoRa - WAN IoT Technology

LoRa (short for long range) is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. Semtech’s LoRa devices and wireless radio frequency technology (LoRa Technology) is a long range, low power wireless platform that has become the de facto technology for Internet of Things (IoT) networks worldwide. LoRa Technology enables smart IoT applications that solve some of the biggest challenges facing our planet: energy management, natural resource reduction, pollution control, infrastructure efficiency, disaster prevention, and more. Semtech’s LoRa Technology has amassed over 600 known uses cases for smart cities, smart homes and buildings, smart agriculture, smart metering, smart supply chain and logistics, and more. With over 50 million devices connected to networks in 95 countries and growing, LoRa Technology is the DNA of IoT, creating a Smarter Planet.

LoRa Wireless RF Technology

A Semtech innovation, LoRa Technology offers compelling features for IoT applications including long range, low power consumption and secure data transmission. The technology can be utilized by public, private or hybrid networks and provides greater range than cellular networks. LoRa Technology can easily plug into existing infrastructure and enables low-cost battery-operated IoT applications. Semtech builds LoRa Technology into its chipsets which are incorporated into devices manufactured by a large ecosystem of IoT solution providers, and connected to networks around the globe. Simply stated, LoRa

LoRaWAN Means

The LoRaWAN open specification is a low power, wide area networking (LPWAN) protocol based on LoRa Technology. Designed to wirelessly connect battery operated things to the Internet in regional, national or global networks, the LoRaWAN protocol leverages the unlicensed radio spectrum in the Industrial, Scientific and Medical (ISM) band. The specification defines the device-to-infrastructure of LoRa physical layer parameters and the LoRaWAN protocol, and provides seamless interoperability between devices. While Semtech provides the radio chips featuring LoRa Technology, the LoRa Alliance, a non-profit association and the fastest growing technology alliance, drives the standardization and global harmonization of the LoRaWAN protocol.
The DNA of IoT
Designed for IoT communications, LoRa Technology enables the connection between remote point-of-use devices and LPWANs for delivery to analytics applications.

Devices

LoRa Modulation: Semtech’s LoRa Technology is the physical (PHY) silicon layer, or wireless modulation, used to create the long range communicatio­n link.
Transceivers & End-Nodes: Transceivers configured with LoRa Technology are embedded into end-nodes, or sensor devices, designed for a multitude of industry applications.
Picocells & Gateways: Sensors capture and transmit data to gateways over distances near and far, indoor and outdoor, with minimal power requirement.

Networks

Network Server: Gateways send information via Wi-Fi, Ethernet or cellular to the network server, which is responsible for network management functions like over-the-air activation, data de-duplication, dynamic frame routing, adaptive rate control, traffic management, and administration.

Applications

Application Servers & Cloud IoT Services: Applications interpret the data collected by LoRa-enabled devices, applying techniques like machine learning and artificial intelligence to solve business problems for a Smarter Planet.
Low-power wide-area network is an indispensable part of the Internet of Things. It features low power consumption, wide coverage, and high penetration. It is suitable for applications that send and receive small amounts of data every few minutes. The LPWAN-related organization LoRa Alliance currently has 145 members worldwide, and its luxuriant ecosystem makes the devices that follow the LoRaWAN protocol highly interoperable.
