UniFi by Ubiquiti has become the de facto standard for Sandton commercial deployments, and for good reason. At ZA Support, we've worked alongside businesses across Johannesburg for over a decade, and we've seen how the right wireless infrastructure transforms office productivity. This guide covers what you actually need to know about UniFi installation in a commercial Sandton environment—not the marketing speak, but the practical realities of deploying these systems in our local context.
What Makes UniFi the Right Choice for Sandton Businesses
UniFi's appeal to Sandton offices is straightforward: enterprise-grade performance without the complexity (or the astronomical cost) of legacy systems. The platform gives you centralised management, meaning you can troubleshoot and adjust your entire network from a single dashboard. For a business spread across two floors or multiple office suites, this matters.
The ecosystem itself is robust. A UniFi installation typically comprises access points (usually the U6+ or U6E models for commercial spaces), a dream machine or controller, and managed switches if you're wiring beyond what your building already provides. We've installed systems for over 18,000 client deployments across the Johannesburg metro, and the pattern is consistent: UniFi scales beautifully from a single-floor office to a multi-building campus.
Load shedding adds another layer of complexity that local installers understand. Your access points need UPS backup, your controller needs failover logic, and your guest network shouldn't grind to a halt when Eskom switches off your block. A proper Sandton installation accounts for this from day one.
The Assessment and Planning Phase
Any competent UniFi installer in Sandton will start with a proper site survey, not a quote based on a phone call. We charge from R599 for a full assessment—this covers a walk-through of your space, signal strength mapping with specialist equipment, identification of interference sources (and Sandton has plenty, given the density of networks in office parks), and a written report with recommendations.
During this assessment, we're looking at your building's construction. Sandton's modern office parks often feature lots of glass and steel, which plays havoc with WiFi propagation. A single access point on the ground floor won't reach your second floor reliably. We map these dead zones, recommend placement, and discuss whether you need hardwired uplinks between access points or whether meshing is sufficient.
This phase also includes a review of your current internet service. Most Sandton businesses have fibre, which is excellent—but some are still on legacy copper lines or dual-connectivity setups. Your UniFi controller needs to account for your WAN configuration, and a proper installer will discuss failover, band steering, and guest network isolation with you before a single cable is run.
Installation and Configuration
The physical installation is straightforward if you've planned correctly. Access points are ceiling-mounted or wall-mounted depending on your space. We typically recommend Ubiquiti's PoE-injected access points—they draw power from your network cable, which simplifies cabling runs and means you don't need electrical outlets above your ceilings.
The controller is where the intelligence lives. For a Sandton office, we typically recommend a UniFi Dream Machine (the larger model if you have more than 50 devices) rather than relying on a cloud controller. Local control means your network functions even if your internet drops—increasingly important given South Africa's ISP reliability challenges.
Configuration covers several critical steps. Site creation in the UniFi interface is where you define your network topology. VLAN setup is essential for guest isolation—your visitors shouldn't see your internal file shares or printers. We configure band steering so devices automatically connect to the strongest 5 GHz band rather than defaulting to congested 2.4 GHz. Airtime fairness gets enabled to prevent slow legacy devices from dragging down your entire network.
Security is non-negotiable. Your WPA3 password gets set strong (not "Guest123"). Rogue AP detection gets enabled. Guest network pre-authorisation means your receptionist can send WiFi credentials to visitors without blasting your main network open.
We back all this up. A proper installation includes configuration export so you can restore the system if hardware fails.
Ongoing Support and Warranties
Here's where most cheap installers fall short: they hand you the keys and disappear. At ZA Support, every UniFi installation comes with up to a 3-year warranty covering hardware failure and configuration support. This matters. UniFi controllers do fail occasionally. Access points wear out. Your network requirements change when you hire more staff or add a meeting room.
Post-installation support includes monthly health checks—we log into your controller, verify that all devices are connecting as expected, check for rogue devices, and ensure firmware is current. When load shedding hits and devices behave strangely, you've got someone who understands the system locally in Hyde Park and can advise whether it's a network issue or a device issue.
We've provided support to over 42,000 networked devices across Johannesburg, and that experience matters when something goes wrong at 4pm on a Friday.
Long-Term Scaling
Sandton businesses grow. A single access point that worked for your original ten-seat office becomes insufficient for thirty seats spread across multiple areas. A proper UniFi installation is built with scaling in mind. Your controller has the capacity to manage dozens of access points. Your network design leaves room for additional switches, additional uplinks, and additional access points without requiring a complete redesign.
We've also seen how Sandton's commercial real estate is becoming more flexible—businesses shift between suites or add temporary spaces. A modular UniFi design survives these transitions better than legacy wired networking.
Why Local Installation Matters
UniFi is standardised globally, but Sandton isn't. A Sandton UniFi installation must account for Johannesburg's specific challenges: load shedding, variable internet quality, the density of interference from neighbouring networks, and the specific characteristics of the buildings you're in. Someone installing UniFi in a Sandton office park has probably installed it in the office park across the road, understands how the buildings behave, and knows which access point placement works in similar layouts.
It's why we don't believe in cookie-cutter installations. We assess your business, design for your specific space, and configure for your specific needs.

Frequently Asked Questions
Q: How much does a UniFi installation cost for a typical Sandton office?
A professional installation starts from our R599 assessment fee. A typical small-to-medium Sandton office (up to 20 users, single floor) runs R8,000–R14,000 for hardware and installation. Larger spaces with multiple floors or access points scale accordingly. We provide a fixed quote after your assessment.
Q: How long does installation take?
Most Sandton installations are complete in one to two days. Small single-access-point setups take 4–6 hours. Multi-access-point deployments with cabling runs take longer. We schedule around your business hours so you're not offline during your working day.
Q: Do I need to replace my existing internet connection?
No. UniFi works with whatever internet connection you have—fibre, copper, or dual connectivity. Our installer will review your WAN setup during the assessment and recommend optimisations if needed.
Q: What happens when load shedding hits?
Your UniFi access points stay online if they're connected to a PoE switch with UPS backup. The controller needs UPS support too. During Stage 6 load shedding, your wireless network will function as long as your backup power holds out. We discuss UPS sizing during the assessment.
Q: Can I expand my UniFi network later?
Absolutely. UniFi is designed for scaling. Adding more access points, switches, or even a second controller is straightforward. Your controller can manage dozens of access points. We've included room for expansion in our initial design.
Q: Who maintains the system after installation?
That's on you operationally, but we offer maintenance contracts covering monthly health checks, firmware updates, and support when issues arise. Most Sandton businesses choose a maintenance package rather than managing it themselves—it's simply more reliable.
