LoRa, short for Long Range is a technology developed by Semtech. It is a new wireless protocol designed for long-range, low-power communications. It is spread spectrum modulation technique that is derived from chirp spread spectrum (CSS) technology.
LoRa devices enable IoT devices to create a smarter planet. It is preferred in IoT application since it is long range, low power consumption and secure data transmission. It can be integrated into existing infrastructure. It also enables low-cost battery-operated IoT applications.
The range is more than 10 km upto 20 km. Other factors such as the network and node-gateway positioning, surrounding environment (presence of physical obstacles), antenna performance, Tx power mode, etc.
Based on LoRa technology, LoRaWAN open specification is a low power, wide area networking (LPWAN) protocol. It is designed to wirelessly connect battery operated things to the Internet. This can be done in regional, national or global networks, and the LoRaWAN protocol leverages the unlicensed radio spectrum in the Industrial, Scientific and Medical (ISM) band.
Features of LoRa Technology:
- Long Range
- Low Power
- High Capacity
- Low Cost
There are multiple technologies in the market, but most of them are slow in gaining global adoption. LoRa is one technology which is being used extensively worldwide and growing substantially. Over 178 million devices are connected to networks in 100 countries, with that, LoRa devices are creating a Smarter Planet.
Ethertronics®, an AVX group company also has the LoRa Module ETH-LORA-M-AX-01 which is a SMT mounted radio module. It operates in the unlicensed 868 MHz and 915 MHz bands.
It combines the performances of the embedded LoRa™ transceiver SX1272 of Semtech Corporation with the benefits of Ethertronics Active SteeringTM and Ethertronics Impedance matching solution to maximize antenna performances and Link budget.
