When deploying a LoRaWAN network, the choice of antenna is one of the key factors affecting communication performance and device stability. Especially for outdoor LoRaWAN gateways, it is common to find that they predominantly use N-type connector antennas instead of other types of antenna interfaces. So, why has the N-type connector antenna become the preferred choice for outdoor gateways? This article will provide a technical, structural, and environmental adaptability overview.
1. Structural Advantages of N-Type Connector Antennas
The N-type antenna interface is a threaded RF connector that offers good mechanical strength and sealing performance. It was originally designed for military and industrial communication systems and has the following advantages:
- Stable Connection: The N-type interface uses a threaded fixation, making it less prone to loosening, suitable for outdoor environments with frequent vibrations.
- Good Waterproof Performance: The N-type connector supports IP67 sealing design, making it suitable for use in harsh conditions such as rain and humidity [1].
- Stable High-Frequency Performance: The N-type interface is suitable for UHF and microwave bands, effectively supporting the frequency bands used by LoRaWAN, such as 433MHz, 868MHz, and 915MHz [4].
These characteristics make the N-type connector antenna an ideal choice for outdoor gateways.
2. High Environmental Requirements for Outdoor Gateways
Outdoor LoRaWAN gateways are typically deployed in outdoor, industrial sites, construction sites, and power facilities and face challenges such as high temperatures, low temperatures, humidity, rain, dust, and UV radiation [1].
In these scenarios, the antennas of the gateways must not only ensure good communication performance but also possess:
- Wind and Shock Resistance
- Long-term Stable Operation Capability
- Water and Dust Resistance
The N-type connector antenna meets these requirements, which is why it is widely adopted.
3. Strong Compatibility, Supporting Various Antenna Options
The N-type connector antenna interface has widespread compatibility, allowing it to adapt to various types of antennas, including:
- Omni Antenna
- Directional Antenna
- High Gain Antenna
This flexibility allows users to choose the appropriate antenna type based on actual deployment needs (such as coverage area, signal directionality, and installation height), thereby optimizing network performance [4].
4. Manthink GDO51 Series Gateway: A Typical Application of N-Type Connector Antennas
Manthink, a domestic manufacturer deeply engaged in LoRaWAN technology, has adopted the N-type connector interface for its GDO51 series outdoor gateways, combined with an IP67 protection level design to ensure stable operation in various complex environments.
Highlights of the GDO51 Series Gateway:
- N-type Connector Interface: Supports multiple antenna connections, enhancing deployment flexibility [1].
- IP67 Protection Level: Dustproof and waterproof, suitable for harsh outdoor environments [1].
- High-Performance LoRa Module: Supports multi-channel concurrency and long communication distances.
- Compatible with Mainstream NS Platforms: Including Manthink’s self-developed ThinkLink LoRaWAN NS platform, supporting 1000 free device connections [3].
5. Conclusion
The widespread adoption of N-type connector antennas in outdoor LoRaWAN gateways is due to their:
- Good Waterproof Sealing
- Stable Mechanical Connection
- Wide Antenna Compatibility
- Ability to Adapt to Complex Outdoor Environments
These advantages make it the preferred solution for outdoor gateway antenna interfaces.
If you are deploying a LoRaWAN network, the Manthink GDO51 series gateway is a reliable choice, combined with its free ThinkLink NS platform, which can significantly reduce deployment barriers and operational costs.
