Best Point-to-Point Wireless Link for 5 km in the UAE (2026 Guide)

For a 5 km wireless link in the UAE, the safe default is a pair of 5 GHz airMAX ac dishes with 25 to 27 dBi of gain, such as two Ubiquiti PowerBeam 5AC units, mounted with clear line of sight. A pair of 23 dBi LiteBeam 5AC Gen2 radios can also cover 5 km when the path is clean and you need less margin, and Ubiquiti airFiber 5XHD with dish antennas is the step up when the link carries an ISP or business backbone. 60 GHz radios are the wrong tool at this distance. This guide explains why, with live AED prices for each option.

The short answer: which kit for a 5 km link

Prices above are pulled live from our store, so they always match today’s price. Point-to-point radios are always bought in pairs: one at each end of the link.

Why 5 GHz, and why not 60 GHz, for 5 km

60 GHz radios such as the GigaBeam Long-Range and the airFiber 60 HD deliver multi-gigabit speeds, but they are designed for links of up to about 2 km, and oxygen and humidity absorb 60 GHz energy quickly. On the Gulf coast in summer, a 5 km 60 GHz shot would spend much of the year failing. At 5 GHz the signal travels much further with far less weather loss, which is why almost every 3 to 15 km link in the UAE runs on 5 GHz airMAX or airFiber.

Line of sight: the part people get wrong

A clear visual line between the two dishes is not enough. Radio waves travel in a football-shaped zone around that line, called the Fresnel zone, and at least 60 percent of it should be free of buildings, trees and cranes. For a 5 km link at 5.8 GHz, the Fresnel zone is about 8 metres in radius at the midpoint, so you need roughly 5 metres of clearance above anything in the middle of the path. In practice that means:

• Mount both dishes higher than you think: on a rooftop pole or mast, not the side of a wall.
• Look hard at the middle of the path. A warehouse roof or palm trees halfway along can break a link that looks clear from either end.
• Over 5 km the Earth’s curvature adds less than half a metre, so it is not the problem. Obstacles are.

Why gain matters more in the UAE

Over 5 km at 5.8 GHz, free-space loss is about 122 dB before anything else gets in the way. Every extra decibel of antenna gain on each end becomes fade margin: headroom that keeps the link up through summer haze, dust storms, coastal humidity and slight misalignment as poles expand in 50-degree heat. That is why we recommend the 27 dBi PowerBeam 5AC 500 as the default for 5 km rather than the smallest radio that technically connects. A link that works in March but drops every afternoon in August is a false saving.

Ubiquiti or MikroTik for a point-to-point link?

Both work well at 5 km. Ubiquiti airMAX is the easiest to align and manage, and most installers in the UAE know it. MikroTik radios such as the QRT 5 and LHG 5 ax run RouterOS, so they make sense when the rest of your network is MikroTik and you want routing, firewalling or bandwidth queues on the radio itself. Do not mix brands on the two ends of one link: airMAX and RouterOS wireless protocols are not designed to talk to each other. For a fuller comparison, read MikroTik vs Ubiquiti for small business.

When to step up to airFiber

If the link is an ISP backhaul, joins two offices with servers on each side, or must carry many CCTV streams plus internet, look at airFiber 5XHD, which is rated at 1+ Gbps. It is a radio only, so you pair it with a dish on each end: the 23 dBi, 30 dBi or 34 dBi airFiber X dish. For 5 km, the 30 or 34 dBi dish gives the most margin. Our ISP equipment guide covers the full backhaul and sector setup.

Installation checklist for UAE sites

• Use outdoor-rated shielded Ethernet cable and ground the pole and the radio. Lightning and static are real risks on exposed rooftops.
• Fit UV-resistant cable ties and drip loops. Sun destroys cheap plastic within a summer.
• Align with the radio’s signal tools, aiming for matching signal levels on both ends, then lock the brackets firmly.
• Choose a clean channel and a sensible channel width. A narrower channel is often more stable over 5 km than the widest one.
• Buy genuine, distributor-supplied radios with a UAE warranty. Grey imports are a common cause of early failure. See how to spot grey-market Ubiquiti.
