The IoT industry is bringing lots of technology and solutions to the market with chip manufacturers investing heavily in the market growing the industry exponentially. It isn’t however without its challenges. One of the key challenges in building out the internet of things is ensuring that those “things” or end nodes are in fact able to communicate with the internet. The sheer number of current internet devices is massive and is expected to hit 25 billion by 2020. Any network that supports such an infrastructure needs to have the ability to handle the traffic. These issues don’t include the fact that nodes need to run on some sort of battery power, have weak radios and also are limited in memory and processing power.
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 Technology offers an efficient, flexible and economical solution to real-world problems in rural and indoor use cases, where cellular and Wi-Fi/BLE based networks are ineffective. Learn why LoRa is becoming the de facto standard of low power wide area networks (LPWAN).
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.
