Gateway Placement Guide

1. Introduction to Gateway Placement

Proper gateway placement is the foundation of a successful LoRaWAN deployment. A well-placed gateway can provide coverage for several kilometers in open areas or an entire building in indoor scenarios.

The key factors that affect coverage include: height above ground, line of sight to sensors, interference from other radio sources, and the surrounding environment (urban, suburban, or rural).

2. Site Survey Process

Before installing a gateway, conduct a thorough site survey:

• Identify potential mounting locations with good height and visibility
• Check for power and network connectivity availability
• Assess RF environment for potential interference
• Document any obstacles that might block signals
• Consider environmental factors (weather exposure, vandalism risk)

3. Height and Line of Sight

Height is often the most important factor in gateway placement. As a general rule:

• Rooftop installations provide the best coverage for outdoor deployments
• Each additional meter of height can significantly extend range
• Avoid placement near large metal structures or other antennas
• Ensure the Fresnel zone is at least 60% clear for reliable links

4. Antenna Selection

Choose the right antenna for your deployment scenario:

• Omnidirectional: 360° coverage, ideal for central locations
• Directional: Focused beam, better for long-range point-to-point
• High-gain: Extended range but narrower coverage angle
• Consider weatherproofing and mounting requirements

5. Coverage Testing

Always test coverage after installation:

• Use a field test device to measure RSSI and SNR at key locations
• Test at the edges of your expected coverage area
• Document any dead spots for future reference
• Consider seasonal variations (foliage, weather)
