The Chinese name of LoRa is Long Range Radio, which is a low-power wide area network communication technology. Thanks to the booming development of the Internet of Things, LORA technology has been recognized by the majority of IoT users because of its unique flexibility.
The advantages of LoRa are mainly reflected in the following aspects:
1. Greatly improved receiving sensitivity and reduced power consumption
2. The gateway/concentrator based on this technology supports parallel processing of multiple channels and multiple data rates, and the system capacity is large.
3. Systems based on terminals and concentrators/gateways can support ranging and positioning.
LoRa collection terminal product introduction

LoRa collection terminal application scenarios
LoRa technology can provide long-distance two-way communication and secure data transmission, and cover urban areas with minimal network infrastructure. Therefore, LoRa collection terminals are widely used in various application scenarios such as smart buildings, smart agriculture, and industrial automation.
edifício inteligente
For the renovation of buildings, sensors such as temperature and humidity, safety, harmful gas, and water flow monitoring are added and the monitoring information is uploaded regularly, which facilitates the supervision of managers and makes it more convenient for users. Generally speaking, the communication of these sensors does not need to be particularly frequent or to ensure particularly good service quality, so the LoRa collection terminal is a more suitable choice in this scenario.
Agricultura inteligente
For agriculture, low-power and low-cost sensors are urgently needed. The application of sensors such as temperature and humidity, carbon dioxide, and salinity is of great significance to agriculture in increasing production and reducing water consumption. However, these data indicators will not change significantly in a short period of time, and the data volume is small and requires real-time performance. Not high, so LoRa collection terminal is undoubtedly the best choice.
Automated manufacturing
In the automated industrial production environment, a large number of intelligent technologies are applied, and various information data are exchanged in the network. Therefore, the characteristics of the selected network are directly related to the execution quality of the production plan. Some scenarios require low-cost sensors with low power consumption and long-life batteries to track equipment and monitor status. In this case, LoRa collection terminal is a reasonable choice.
