SOLUTIONS BASED ON LORAWAN DEVICES
LoRa is a wireless modulation technique derived from Chirp Spread Spectrum (CSS) technology. Encodes information into radio waves using “chirping” pulses
LoRa is an ideal technology for connections over long distances, where information is communicated that involves little volume of data and the sensors do not have network power.
Due to its high penetration and low cost of implementation, this technology is increasingly used to transmit information inside buildings.
LoRaWAN is a Medium Access Control (MAC) layer protocol built on top of LoRa Modulation. It is a software layer that defines how devices use LoRa hardware.
A typical LoRaWAN network architecture is made up of nodes and gateways .
- Ultra low power – LoRaWAN end devices are optimized to operate in low power mode and can last up to 10 years on a single coin cell battery
- Long range – LoRaWAN Gateways can transmit and receive signals at a distance of 10 kilometers in rural areas and up to 3 kilometers in dense urban areas.
- Deep indoor penetration – LoRaWAN networks can provide deep indoor coverage and easily cover multi-story buildings.
- License free spectrum – We do not need to pay a license for the use of the frequency spectrum to implement a LoRaWAN network.
- High capacity – LoRaWAN Network Servers can handle millions of messages from thousands of Gateways
- End-to-end security – LoRaWAN ensures secure communication between the end device and the Network Server using AES-128 encryption.
- Firmware updates over the air – Firmware can be updated remotely for a single end device or group of end devices.
- Low cost – Minimal infrastructure, low cost end nodes and open source software.
- Certification program – The “LoRa Alliance certification program” certifies end devices and gives end users the confidence that the devices are reliable and compliant with the LoRaWAN specification.
