LoRa terminal equipment

LoRa terminal equipment

　　 LoRa's terminal nodes may be various devices, such as water and gas meters, smoke alarms, pet trackers, etc. These nodes are first connected to the LoRa gateway through LoRa wireless communication, and then connected to the network server through a 3G network or an Ethernet network. The gateway and the network server communicate through the TCP/IP protocol.

　　 LoRa network divides terminal equipment into three categories: A/B/C:

　　Class A: Two-way communication terminal equipment. This type of terminal device allows two-way communication, and each terminal device's uplink transmission will be accompanied by two downlink reception windows. The transmission time slot of the terminal equipment is based on its own communication requirements, and its fine-tuning is based on the ALOHA protocol.

　　Class B: Two-way communication terminal equipment with preset receiving time slots. This type of terminal device will open the redundant receiving window at a preset time. To achieve this goal, the terminal device will receive a Beacon from the gateway synchronously, and synchronize the time of the base station and the module through the Beacon.

　　Class C: Two-way communication terminal equipment with the largest receiving window. This type of terminal device continues to open the receiving window, and only closes during transmission.

　　LoRa application prospects:

　　 At present, the LoRa network has been piloted or deployed in many parts of the world. According to data released earlier by the LoRa Alliance, 9 countries have started to build networks and 56 countries have started pilot projects.

　　For some foreign telecom operators who are not too affluent, they may be more willing to use low-cost LoRa networks. However, it is entirely possible and feasible for some companies to use LoRa technology to build small private networks to implement some applications.
