LoRa stands for Long Range. It is a LPWAN technology which stands for low power wide area network. It is based on chirp spread spectrum (CSS) technology.
It is a way to manipulate radio wave by using multi symbol format to encode information, a system which supports this radio manipulations, basically a communication network of IoT, which connects sensors to cloud and enables communication of data at real-time. It is economically more suitable then other networks.
Few features of LoRa are
- Read range is 8-12 KM
- Battery backup is for 3-5 years, depending on use
- Limited transfer of data
- Sensors can be connected such as, temperature, water level, electric meter, etc
- Radio frequency bands are 433MHz, 868MHz, 915MHz, 923MHz.
