What is LoRa?

LoRa is a new wireless technology for long-range and low power consumption, which is preferable for building Internet networks of things around the world.

The introduction of clever technologies of the Internet of things improves life in big cities, which face problems caused by climate change, pollution of the environment, increased consumption of resources. Business also receives significant benefits in terms of lower transaction costs and improved efficiency.

LoRa's wireless technology is being introduced into inventory devices, street lighting, industrial equipment, home devices, wearable gadgets and allows solving the pressing problems of the digital world.

LoRa Technology

The innovative LoRa technology combines a whole range of remarkable features: wide range, low power consumption, secure data transmission. The uniqueness of the LoRa modulation is the high sensitivity of the receiver (up to -134 dBm) and data transmission provided that the carrier signal is substantially lower than the "noise" level.

Public and private networks using this technology can provide more coverage than existing cellular networks. Simplicity of connection, integration into the existing infrastructure and good scalability make LoRa an ideal solution for many applications in the field of Internet stuff. LoRa chipsets are built into various devices and equipment to provide wireless data transmission in the networks of Internet operators things, such as «Lartech Telecom».

LoRaWAN Protocol

LoRaWAN is a data transfer protocol in a network with multiple nodes and a star topology developed by LoRa Alliance. To transfer data between remote sensors and gateways connected to the LoRaWAN wireless network, an unlicensed radio frequency band (868 MHz in Russia) is used. Based on the standards of building LPWAN networks, the LoRaWAN protocol allows you to quickly deploy both public and private Internet networks of things, using hardware and software that provide a symmetric secure communication channel, interoperability, mobility and energy efficiency. The LoRaWAN protocol specification is free and available for download on the LoRa Alliance website.
