How to Choose a 20km WiFi Access Point: A Comprehensive Buyer’s Guide
Selecting a reliable 20km long-range WiFi access point is a critical decision for service providers, rural network operators, and enterprise customers aiming to deliver high-speed connectivity over vast distances. While many vendors claim to offer 20km range, performance varies significantly based on technology, environment, and configuration. This guide outlines the essential factors to evaluate before placing bulk orders, ensuring you choose a solution that delivers consistent, real-world performance.
Important Note: Achieving a true 20km wireless link is highly dependent on environmental conditions and proper installation. Always verify product specifications with real-world performance data, not just theoretical claims.
Key Features to Consider When Selecting a 20km WiFi Access Point
- Range and Real-World Performance
While the target distance is 20 kilometers, real-world conditions such as terrain, foliage, buildings, and atmospheric interference can degrade signal strength. Therefore, it’s wise to select a model engineered to exceed 20km under ideal conditions—ideally offering a maximum theoretical range of 25–30km. This buffer ensures reliable connectivity even when faced with partial obstructions or signal attenuation.
Look for access points that use advanced modulation techniques (like OFDM or MIMO) and high-sensitivity receivers to maintain stable links at extreme distances. Also, consider models with adaptive rate control, which automatically adjusts data rates to maintain connectivity as signal strength fluctuates.
- Line of Sight (LoS) Requirements

Even minor obstructions like tree branches or building edges can cause signal diffraction, reflection, or absorption, leading to dropped connections or reduced throughput.
For optimal performance, install the access point on elevated structures such as towers, rooftops, or masts. Conduct a site survey using tools like Google Earth or RF path planners to verify LoS. In cases where LoS is partially blocked, consider models with strong non-line-of-sight (NLoS) capabilities, often achieved through lower frequency bands (e.g., 900MHz or 2.4GHz) and beamforming technology.
- Transmit Power and Antenna Gain
A 20km link demands both high transmit power and high-gain directional antennas. The combination amplifies signal strength and focuses it in a narrow beam, increasing reach and reducing interference.
Typical long-range access points offer transmit power up to 30 dBm (1 watt) and support external antennas with gains of 20–30 dBi. However, be aware of local regulatory limits—such as those set by the FCC (USA), ETSI (Europe), or other national bodies—on EIRP (Effective Isotropic Radiated Power), which combines transmit power and antenna gain.
Retailers and integrators must ensure compliance to avoid legal issues or interference with other wireless services. Always verify that the product is certified for use in your target region.
