LoRa is a wireless technology that provides long-range, low power and secure data transmission for IoT and M2M applications. It is a chirp spread spectrum based modulation that has low power characteristics like FSK modulation. However, it is helpful for long-range communications. LoRa wireless is handy in connecting sensors, machines, gateways and devices.
LoRa Technology operates all around the world in different frequency bands. For example, it operates on the 865 to 867 MHz and 920 to 923 band in different regions of Asia. Moreover, it operates in the 868 MHz bands in Europe.
LoRa wireless technology basis
There are many key elements of LoRa technology. For example, it includes millions of nodes worldwide and LoRa wireless range is almost from 15 to 20 km long. Furthermore, LoRa wireless system comes with a long battery life that is enough for almost 10 years.
There are many factors that provide the overall connectivity and functionality to the LoRa wireless system:
LoRa PHY/ RF interface
The LoRa Physical layer plays a significant role in system operation. It basically governs the aspects of the RF signals transmitted between the endpoints or nodes. The radio interface or physical layer governs aspects of the signal that includes modulation format, frequencies, and power levels. Furthermore, this layer also controls the signaling between the transmitting and receiving elements and some other similar topics.
LoRa Protocol Stack
Likewise LoRa PHY, LoRa Alliance has defined an open protocol stack. It has enabled the concept of LoRa technology to grow due to different types of companies involved in LoRa’s development. As a result, LoRa protocol is easy to use, low-cost solutions for connectivity and other matters.
LoRa Network Architecture
Likewise RF, there are some other elements of the LoRa wireless network. It includes system architecture, server, and applications, backhaul. So the term for overall architecture is LoRaWAN.
