In today’s world of communication, Long Range (LoRa) technology has taken a significant role, providing strong, long-distance connections. LoRa’s way of sending signals and its impressive reach make it an ideal option for many direct and indirect network paths. This article explores how LoRa works in two situations: when devices can see each other (line-of-sight…
How LoRa can impact smart cities with parking sensors
In this article, we’ll configure a parking sensor using LoRa (long-range) devices. LoRa is a wireless communication technique derived from Chirp Spread Spectrum (CSS) technology. For this project, Arduino Nano is connected to an ultrasonic sensor, detecting parking occupancy based on distance measurements. When a vehicle enters or leaves a parking space, the ultrasonic sensor…
What is Chirpstack?
ChirpStack is an open-source LoRaWAN Network Server that enables communication between LoRaWAN devices and applications. It has a complete set of components, including a Network Server, Gateway Bridge, and Application Server, that can be used to set up and manage a LoRaWAN network. LoRaWAN is a network layer protocol maintained by the LoRa Alliance to…
How communication works between two LoRa end-node devices
Communication between two LoRa end-node devices can happen seamlessly. Both end-node devices include the LoRa E5 Mini Board, which switches quickly between sending and receiving messages — making two-way communication possible. In this setup, communication begins with one device sending a message and waiting for confirmation. Upon receipt, the receiving device sends a reply confirming…
How to integrate modules and smart meters with LoRa node-to-gateway communication
LoRa (long-range) technology ensures reliable long-range communication between a node and gateway, providing long-term, low-power use for devices This article provides an explanation of LoRa node-to-gateway communication while introducing a node equipped with two buttons to control the flags. These buttons enable users to turn on or off specific actions associated with each button and…
How LoRa enables long-range communication
LoRa (Long Range) is a type of wireless communication technology designed to send information over long distances with low power consumption. It uses a special technique called chirp spread spectrum (CSS) modulation, which operates by continuously changing the frequency of a transmitted signal over time. This varying frequency generates a waveform (resembling the sound of…
What are LoRa gateways and what types are available?
A LoRa gateway is a wireless communication technology designed for long-range, low-power communication between devices for the Internet of things (IoT). The LoRa gateway receives the data from devices, forwarding it to a network server, which manages the network and handles the data routing and processing. The gateways typically use a dedicated LoRa concentrator chip…
How does LoRa modulation enable long-range communication?
What is LoRa? LoRa (Long Range) is a wireless communication technology that sends information over long distances with low power consumption. It uses a special technique called chirp spread spectrum (CSS) modulation. Chirp Spread Spectrum operates by continuously changing the transmitted signal’s frequency over time. This varying frequency generates a waveform that resembles the sound…
What is the LoRaWAN network and how does it work?
LoRa (“long-range”) is an excellent wireless communication solution without networking capabilities. It’s a reliable, energy-efficient, encryption-secured, low-cost wireless connectivity technology. And as its name suggests, it offers an extremely long range. LoRa operates at the physical layer of an OSI model and is implemented at the chip level — excluding the network management protocol. This…
