The charactristics of Lorawan Gas Meter

1.What are the differences between LoRawan, NB-IoT, and GPRS?

A: LoRawan is a low-power wide-area network (LPWAN) deployment, which can be considered a dedicated switch or WAN for the Internet of Things (IoT). It is suitable for centralized management and does not require carrier traffic.

NB-IoT is narrowband communication, suitable for scattered deployments and areas covered by carrier networks. It consumes less power than GPRS, and its base station capacity is larger, allowing more devices to be placed on a single base station.

GPRS has a larger bandwidth than NB-IoT and is suitable for the same locations, but its base station capacity is lower, making it unsuitable for large-scale deployment. Exceeding the capacity of devices on the same base station will lead to communication failures; it also consumes a lot of power and is prone to premature failure

2. What are the advantages and disadvantages of LoRaWAN smart gas meters?

A: For advantages, refer to the LoRaWAN advantages and disadvantages section.

Advantages: 1. Can be deployed even in areas with poor carrier signal; 2. Centralized management; 3. In Class B mode, it offers both low power consumption and "relative real-time" performance.

Disadvantages: 1. Meters need to be concentrated within a LoRaWAN coverage area, unsuitable for scattered management; 2. Class B requires GPS signal, unsuitable for areas with weak GPS signal.

3.How many meters can one LoRaWAN outdoor gateway connect to?

A: Theoretically, 2000 meters.

4. What is the battery life of LoRaWAN communication, assuming one report per day?

A: 5 years

5. In which environments is LoRaWAN communication suitable for meters?

A: In environments with poor operator performance or centralized management.

6. What are the differences between LoRaWAN Class A, Class B, and Class C?

A: Class A is non-real-time communication; all reports require active submission. Command execution requires active triggering or will only execute after a set active submission time.

Class B, compared to Class A, achieves relatively real-time communication. The device and gateway actively connect once every 128 seconds. Command execution does not require device triggering; it executes when the communication window is open. There is a slight delay in command issuance and execution.

Class C is a constant connection, typically used in electricity meters. Power consumption is not a concern, and command execution is also real-time.
