Sometimes you need to send Internet or network connection from one place to another, far away. Maybe you have two offices, a farm, a factory or a camera site that’s 10-15 kilometers away. Running cables that far is very expensive and difficult. The good news: you can use a wireless bridge.
What Is a Wireless Bridge?
A wireless bridge is a network device that connects two or more separate local area networks (LANs) over a wireless connection. Think of it as a “virtual cable” that replaces a physical Ethernet or fiber run.
For example:
- Point to Point (P2P): Connect two locations directly.
- Point to Multipoint (PTMP): Connect one critical site to multiple remote sites.
Wireless bridges are often built using outdoor radios with highly directional antennas, designed to transmit and receive signals over long distances.
Key Considerations for a 10-15km Wireless Link
Extending a wireless network over long distances requires planning. Here are some important factors to consider:
1. Line of Sight
A clear line of sight between antennas is crucial. Buildings, hills, trees or even cranes can block or degrade the signal. Even if you see the other site visually, you must also account for the Fresnel Zone, an elliptical area around the line of sight path where radio waves propagate. Any obstruction in this zone can reduce performance.
2.Frequency Band Selection
- 5GHz: Widely available, decent throughput, but more susceptible to interference.
- 2.4GHz: Better penetration through obstacles, but lower throughput and heavily congested.·
- Licensed bands (6GHz, 11GHz, 18GHz, etc.): Provide cleaner spectrum but require regulatory approval.
3. Antenna Choice
Use high-gain directional antennas (parabolic dishes, panels or metal grids) for long-distance links. The higher the gain, the better the ability to focus energy over 10–15 km. Many modern antennas support dual-polarization (horizontal + vertical), which allows higher throughput (MIMO technology) and more stable links.
4.Throughput Needs
Plan for both current and future bandwidth requirements. If you need 200 Mbps today, consider equipment capable of 1 Gbps to accommodate growth.
Our Top Choices
If you’re looking to build a stable and high-performance wireless bridge for distances up to 10–15 km, there are several great options. Each one is designed for different scenarios, so you can pick the one that best matches your needs—whether it’s long distance, multi-site coverage, or extreme weather resistance.
802.11ax Outdoor Wireless Bridges
This one gives up to 15 km range in good conditions, with a 19 dBi antenna. It’s good when you want long range plus pretty high bandwidth. For example, if you’re streaming 4K video or moving large files. IP67 rated and comes with surge protection, so it handles rain or dust.
Features:
- Range: up to 15 km (clear line of sight)
- Speed: up to ~900 Mbps
- Antenna: 19 dBi directional
- MU-MIMO & OFDMA support (802.11ax / WiFi 6)
- IP67 weatherproof, built-in 8kV surge protection
WiFi 7 Industrial Outdoor Wireless Bridges
A more modern option: WiFi 7 (802.11be), with strong performance even at long distances (about 500 Mbps at 15 km) and up to 2 Gbps close up. This wireless bridge has a 20 dBi parabolic antenna and high transmit power. It also can deal with big channel bandwidths and rugged settings.
Features:
- Range: up to 15 km
- Speed: up to 2 Gbps at short range, ~500 Mbps at 15 km
- Antenna: 20 dBi parabolic dish
- Support wide channel bandwidths (20–320 MHz)
- Dual power: PoE and DC input
802.11be Outdoor Wireless PTMP Bridge Kit
If you want to connect many remote points to a central hub (for example, several cameras, sensors, or smaller offices), this kind of kit is great. It uses a base station plus bridges, supports many clients, and has good throughput. The range is about 10 km for stable performance.
Features:
- Range: up to 10 km
- Speed: over 2.3 Gbps total throughput
- Kit includes: WiFi 7 base station (AP) + two 802.11ax bridges
- Support multiple users/devices simultaneously
- IP67-rated, wide temperature range
Wi-Fi 7 Outdoor Bridge with Grid Parabolic Antenna
When you’re worried about harsh elements—wind, storms, rain, salt air (if near sea)—this one is made for that. The dish antenna is wind resistant, great for remote sites with bad weather. This bridge supports Wi-Fi 7 (802.11be), suitable for bandwidth-heavy tasks like high-definition video streaming, large data transfers, or running multiple applications at the same time.
Features:
- Range: up to 10 km
- Speed: up to 2.3 Gbps
- Wind-resistant design (metal grid reduces wind load)
- Ideal for coastal, windy, or exposed areas
- Advanced management: VLAN, DHCP, SNMP, WPA2 security
How to Set Up a Wireless Bridge over 10KM?
The installation varies by retailer, but you can refer to the general guidelines below:
Before You Start
- Two outdoor wireless bridges (more units for PTMP deployments)
- PoE injectors or DC power, Ethernet cables, mounting pole/mast
- Tools: ladder, wrench, tape, screwdriver and laptop for configuration
Point to Point Installation
1.Pick the Locations
Make sure nothing (trees, buildings or hills) blocks the line of sight between the two sites. Keep the middle area mostly clear. Install the mounting poles or use rooftops. Confirm how you’ll power each unit (PoE, 12V DC or solar).
2.Mount the Wireless Bridges
Securely attach the bridges to poles, point the bridge to the other by eye (coarse alignment) and lock the mounts loosely for fine tuning. Power both bridges, and if necessary, install lightning/surge protectors and attach a proper ground rod before final power connection.
3.Connect the Wireless Bridges
Connect the main bridge to your router or switch using an Ethernet cable. This will be your Access Point (AP) side. At the remote site, connect the bridge to the device or local switch you want to provide internet to. This unit will be the Client/Station side.
4.Configure the Bridge
- Connect each unit to your laptop or network and open the device web interface.
- Set one unit to Access Point (AP) and the other to Client/Station. Use the same SSID, channel, and security (WPA2/WPA3) on both.
- Set a fixed channel and reasonable channel width. If interference exists, try a different channel. Reduce the transmit power if you see noise.
- Change admin passwords, disable remote admin if unnecessary and update firmware.
5.Align and Fine-Tune
Use the signal strength indicators in the web interface (or LED bars on the unit) while slowly adjusting the antennas. Stop when you reach the strongest and most stable signal, then tighten the mounts firmly. Note final antenna angles, device IPs, and baseline speeds. Check alignment, firmware, and logs every 3–6 months.
Applications
- Rural Networks: Deliver internet access where fiber is not feasible.
- Enterprise Networks: Link multiple campuses or branch offices.
- Surveillance Systems: Provide connectivity for remote CCTV cameras.
- Smart Agriculture: Connect smart sensors, irrigation systems, and monitoring equipment over large farms.
- Disaster Recovery: Quickly restore communications after natural disasters.
- Military and Defense: Establish secure links in field operations.
