When engineers talk about “Mensi Technology’s OM822 module achieving all-weather command reception,” many may wonder: What exactly is LoRa? How is it related to LoRaWAN? Today, we will break it down technically and combine it with the product ecosystem of Mensi Technology to help you understand point-to-point communication clearly.
1. LoRa: The ‘Aerial Bridge’ Across Mountains and Seas
LoRa (Long Range), developed by Semtech, is a **physical layer modulation technology that emphasizes ultra-long range and low power consumption**.
It can be simply understood as the ‘transmitter’ of communication — it solves the problem of how signals penetrate and transmit stably in environments filled with high-rise buildings and metal shielding.
Core Highlights:
– Wall-penetrating capability: The maximum transmission distance in the 2.4GHz band is 3-5 times greater than traditional FSK/GFSK technologies.
– Energy-saving black technology: Nodes can enter deep sleep mode, maintaining 10 years of operation without recharging is not an exaggeration.
– Intelligent anti-interference: Using spread spectrum modulation to maintain stability in complex electromagnetic environments, ensuring your signal is “never disconnected.”
For a relatable scenario: For instance, when you go on a trip, LoRa is like your fully fueled electric vehicle, while how to avoid traffic and reach your destination accurately relies on the ‘route navigation’ provided by LoRaWAN.
2. LoRaWAN: The ‘Traffic Chart’ Filled with Rules
If LoRa is the ‘engine’ of communication, then LoRaWAN is the well-designed traffic planning system for the entire network. It defines the **data link standards, network access methods, encryption processes, and device management strategies**.
Key features you can see:
1. **Star network architecture**: Nodes can only send data to gateways, and gateways do not bear the task of forwarding (eliminating lengthy signal transmission).
2. **8-channel concurrent reception**: Mensi Technology’s outdoor gateway GDO51 series has 8 independent frequency reception channels, providing an efficient scenario similar to 8 delivery vehicles picking up goods simultaneously.
3. **Adaptive Data Rate (ADR)**: Works with the OMx22 series modules to dynamically adjust data rates and transmission power based on the environment. Just like a driver changing equipment according to weather conditions to ensure stable communication.
Additionally, the thinklink network server hides a self-decision-making system — supporting automatic device online status, heartbeat detection, and data storage, saving engineers from the enormous cost of developing an IoT communication platform from scratch.
3. Understand these three types of LoRaWAN nodes!
LoRaWAN nodes are functionally divided into three ‘personalities’:
**Class A modules**: The quietest presence
– Features: Devices autonomously decide when to send, only briefly opening two receiving windows after sending.
– Advantages: Average annual power consumption is controlled at the level of flow monitoring devices (e.g., rainwater well cover displacement alarm).
– Application: The energy-saving terminals in the Mensi OMx22 series adapt to Class A standards, making them the first choice for wireless sensors.
**Class B nodes**: The guardian on scheduled patrols
– Incorporates a “heartbeat command” mechanism, confirming location to the gateway at fixed intervals.
– Example: Urban road manhole cover theft monitoring network, where the server can actively wake nodes to return data.
**Class C modules**: The sentinel that never goes offline
– Nodes are mostly in listening mode, like you have 10 receiving windows watching the message panel.
– Disadvantage: Requires external power support, but responses are the most timely.
– Mensi solution: The OMx22 Class C module combined with the thinklink platform supports critical applications like remote control of fire-fighting equipment.

5. Should you choose LoRa or LoRaWAN? Three points to see through the essence
– **Private transmission prioritizes LoRa chips**
– **Multi-level management prefers LoRaWAN**: The thinklink server provides device online rate statistics, geofencing, and OTA remote upgrades;
– **Extreme long-range + designated reception**: The Mensi OMx22 series Class C terminals combined with low-latency frequency bands have been validated for five years of battery life.
Conclusion: The Mensi Technology OMx22 module/GDO51 outdoor gateway/GDI51 indoor gateway have been implemented in over 200 smart construction sites and agricultural demonstration bases nationwide.
