Lora (Long Range) is a patented digital communication technology developed by Cycleo of Grenoble, France, and acquired by Semtech in 2012. Lora uses license-free sub-gigahertz radio frequency bands like 169 MHz, 433 MHz, 868 MHz (Europe) and 915 MHz (North America). Lora enables very-long-range transmissions (more than 10 km in rural areas) with low power consumption. The technology is presented in two parts — Lora, the sical layer and LoRaWAN (Long Range Wide Area Network), the upper layers.
Lora and LoRaWAN permit inexpensive, long-range connectivity for the Internet of Things (IoT) devices in rural, remote and offshore industries. They are typically used in mining, natural resource management, renewable energy, transcontinental logistics, and supply chain management.

What is the purpose of an antenna?
An antenna is used to convert electric energy into radio waves which enable communication/ instruction between two points. These are usually a radio transmitter and receiver- no radio device will work without one. Depending on the application, antennas can sometimes be as simple as a piece of k when radio waves reach an antenna and cause the electrons inside it to vibrate. This creates an electric current that duplicates the original v>
What is the Gain?
Gain is a key performance indicator which combines an antenna’s directivity and electrical efficiency. Gain describes how well the antenna converts input power into radio waves headed in a specified direction or vice versa. Essentially, it refers to how well the antenna works to receive or transmit a to if you didn’t have one.
Gain is measured in Decibels (dBi) and the larger the dBi, the more gain it has. High gain antennas are useful for manipulating the ther in one direction and less in another but do not increase the overall. For example, using a high gain antenna on your wifi router would improve the the floor it’s on, but rooms on other floors of the house are likely to have some trouble connecting to the internet.
