The Small-Business UniFi Buying Guide (2026)

If you've researched business networking, you've seen two kinds of advice: consumer gear that falls over when twenty devices connect, and enterprise systems with per-device licensing that costs more than the hardware. Ubiquiti's UniFi line sits in the sweet spot: enterprise features, one dashboard, and no recurring license fees. Here's what a small business actually needs, by size.

The three pieces of every UniFi network

• A gateway — the brain. It routes traffic, runs the firewall, and hosts the UniFi software that manages everything else.
• Switches— the backbone. They connect your wired devices and power your access points and cameras over the network cable itself (PoE), so you don't need outlets in the ceiling.
• Access points — the Wi-Fi. A ceiling-mounted access point covers roughly 1,500–2,500 square feet of typical office space. You add more for capacity and coverage, not because any single one is weak.

A 5-person office or storefront

A compact gateway with built-in Wi-Fi (like the UniFi Express line) or a small gateway plus one access point handles this comfortably. Add a small PoE switch if you have wired desks, a printer, or a camera or two. Budget range including professional installation: usually under $1,500.

A 15-person office

This is where consumer routers visibly give up and where UniFi shines. A dedicated gateway (UniFi Cloud Gateway or Dream Machine class), a 16–24 port PoE switch, and two access points cover most spaces this size. You also want VLANs at this point: separating guest Wi-Fi, company devices, and cameras onto their own network segments — which is configuration work, not extra hardware.

A 50-person, multi-suite office

Now design matters more than the parts list: a site survey and Wi-Fi heatmap determine access point placement, you'll likely run a 48-port PoE switch (or several), and the gateway should be sized for your internet speed with room for failover internet. This is also the size where structured cabling done properly — labeled, tested, documented — pays for itself every time something changes.

Where people go wrong

• Buying access points first. Wi-Fi is only as good as the wired network behind it. Cabling and switching come first.
• Skipping VLANs. Guest Wi-Fi on the same network as your file server is one of the most common security gaps we find in assessments.
• No documentation. Six months later, nobody remembers which port feeds which room. Label and document during the install, not after.

The honest bottom line

UniFi is the best value in small-business networking right now, and it's what we install most often. But the gear is the cheap part; the design, cabling, and configuration determine whether you get enterprise results or an expensive pile of access points. If you want it done once and done right, we design, install, and document UniFi networks across Miami-Dade — here's how our network installs work.
