LoRa Technology

LoRa (s is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology.LoRaWAN is a protocol specification built on top of the LoRa technology developed by the LoRa Alliance. It uses unlicensed radio spectrum in the Industrial, Scientific and Medical (ISM) bands to enable low power, wide area communication between remote sensors and gateways connected to the network. This standards-based approach to building a LPWAN allows for quick set up of public or private IoT networks anywhere using hardware and software that is bi-directionally secure, interoperable and mobile, provides accurate localization, and works the way you expect.

LoRa network is consist of gateways, network servers and End devices. The network topology  used is star of stars. End devices are also known as motes and gateways are known as base stations or concentrators in LoRa network system. End devices and Gateways are connected wirelessly using ISM bands specified with single hop.Gateways and network servers are connected using IP back-haul or 3G/4G broadband connections.

Connects devices up to 30 miles apart in rural areas and penetrates dense urban or deep indoor environments. Requires minimal energy, with prolonged battery lifetime of up to 10 years, minimizing battery replacement costs. Supports millions of messages per base station, meeting the needs of public network operators serving large markets. Reduces infrastructure investment, battery replacement expense, and ultimately operating expenses
