LoRa has revolutionized the world of technology and communication as it has broken the balance between transmission distance and power consumption. LoRa has made it possible to have communication that is long distance, low power consuming, large capacitance and have a low cost of hardware. This has brought tremendous change especially in the field of IoT. There is a wide variety of LoRa modules available and an even larger range of suppliers for LoRa modules which can make the selection of the right LoRa module for a specific application a daunting task. This article gives a brief introduction into LoRa and LoRa modules and then discusses few of the best LoRa module manufacturers and suppliers in USA.
What is LoRa Technology?
LoRa (Long Range) is the standard used for LPWAN Low Power Wide Area Network wireless communication that lasts up to 15 km in suburban environments and more than 2 km in dense urban environments. LoRa is a CSS (Chirp Spread Spectrum) technology that encodes radio wave information using chirp pulse and interacts with a device’s physical layer. It is robust against disturbances making it ideal for long-distance communication with small chunks of data and low bit rates. LoRa has enabled smart IoT applications due to its key characteristics like robustness against disturbances, low power consumption, large system capacity, long distance and low hardware cost.
What is a LoRa Module?
LoRa module is a wireless communication module that is compliant with LoRaWAN networks. Due to the chirp spread spectrum modulation technique, LoRa modules can reach high communication ranges while maintaining low power characteristics. LoRa modules work worldwide without much technical variation, but they work at different frequency ranges in different countries, see the frequency bands for LoRaWAN. The data rate in a LoRa module is adaptable with the use of spreading factors and variable bandwidth. The power level is also adaptive with the variation of link conditions and data rates.
Different types of LoRa modules are available and the most common ones are the basic transceiver-only module, LoRa module with host controller integrated and modems. Selecting a LoRa module is a critical task. Multiple factors should be considered when selecting the right LoRa module for the specific application. Few such factors are the operating environment, transmission range, power consumption, package size, after-sales service and support, cost etc. LoRa modules are used in an extensive range of applications and industries based around IoT such as smart agriculture, smart cities, building management, home automation, asset tracking, smart energy meter readings etc.
The main advantages of using a LoRa module are the low cost, easy deployment to an existing network, long-range communication, and low power consumption. LoRa modules can be used for bi-directional communication globally.
LoRa modules can have just a few disadvantages too based on the application such as low bandwidth, spectrum interference due to constant increase in network deployment, low transmission rates etc.
