WhiteSpace Education Series | The History of WiFi: From “Nice to Have” to Core Building Infrastructure

This article is part of WhiteSpace’s Education Series, where we speak to our colleagues in the industry and collaborate to make building technology clearer, more practical, and easier to navigate.. The goal isn’t hype – it’s understanding, so owners and developers can make informed decisions that hold up over time.  

For this piece, we sat down with Todd Thorpe, Director of Business Development at Cambium, to break down how WiFi evolved inside buildings, why standards keep changing, and how to think about upgrades without overreacting to every new version.

What WiFi 5, 6, and 7 Actually Mean — and How to Think About Upgrades

WiFi Didn’t Become “Critical” Overnight

WiFi didn’t suddenly matter one day.

It quietly evolved from convenience to an expectation to something residents now consider essential infrastructure.

Today, when WiFi underperforms, residents feel it immediately. Owners, meanwhile, are often told they need to “upgrade to the latest WiFi” – without much explanation of what that actually means.

So, the real question becomes:

Do owners need to upgrade—and if so, what are they actually upgrading to?

As WhiteSpace Vice President, Matt Pemberton, puts it:

“Our role is to help owners make eyes-wide-open decisions. Every new WiFi standard brings more capability, but that doesn’t automatically make it the right move. The goal is understanding what actually matters for the building, the resident experience, and the long-term plan—not just reacting to what’s new.”

To answer that, it helps to understand how WiFi standards work, where they came from, and what actually changes from one generation to the next.

Before WiFi Versions Even Existed

Before WiFi was part of daily life, buildings were wired for one thing: television.

From the 1960s through the 1980s, most multifamily buildings were built with coax cable, designed to bring cable TV to a single location in each unit. It worked well for its time – and stayed in place far longer than anyone expected.

When internet service arrived, there was no big redesign. Internet simply rode on top of existing wiring.

“Back then, coax was the only option,” Todd explains. “When internet came along, it just used what was already there.”

Key takeaway: Infrastructure decisions last decades. Technology changes faster than buildings do.

So… Was There a WiFi 1, 2, 3, or 4?

Yes – sort of.

Early WiFi versions existed, but they weren’t marketed to consumers the way today’s standards are.

• WiFi 1–3: Early, slow, and mostly experimental
• WiFi 4 (802.11n): The first truly mainstream WiFi (late 2000s)

WiFi 4 introduced:

• Better range
• More reliable connections
• The ability to handle multiple devices reasonably well (at the time)

This was the era when WiFi started showing up in apartments as something residents expected – not a bonus.

WiFi 5: Faster, but Still Unit-by-Unit

WiFi 5 (802.11ac) arrived in the early 2010s.

What improved:

• Faster speeds
• Better performance for streaming
• Stronger connections at shorter distances

What didn’t change:

• Each apartment still operated like its own island
• Routers were placed randomly
• Performance depended heavily on walls, wiring, and interference

At the same time, many buildings adopted bulk internet – where the owner pays for service and includes it in rent.

But as Todd puts it:

“Bulk WiFi is really just a billing model. The technology can be exactly the same.”

Key takeaway: Who pays for internet doesn’t determine how well WiFi works.

The Breaking Point: When WiFi Became a Building Problem

By the mid-2010s, things changed fast.

Devices multiplied. Streaming replaced cable. Remote work became normal. Complaints increased – not because residents understood networks, but because reliability suddenly mattered more than peak speed.

“Wireless performance depends on wired decisions,” Todd says.

That realization marked a shift: WiFi stopped being a resident problem and became a building-wide responsibility. 

WiFi 6: Built for Density, Not Just Speed

WiFi 6 (802.11ax) wasn’t about being flashy. It was about handling reality.

What WiFi 6 does better:

• Manages many devices at once
• Reduces congestion in busy buildings
• Improves consistency, not just raw speed
• Works better in dense environments like apartments and condos

This is why WiFi 6 became the backbone of Managed WiFi – a design approach borrowed from hotels and student housing.

Instead of treating each unit as a standalone setup, buildings began designing WiFi as a shared system – using centralized planning, strong Ethernet or fiber backbones, and intentionally placed access points

“That’s when WiFi stopped being random and started being designed,” Todd says.

Key takeaway: WiFi 6 succeeded because it matched how people actually live.

WiFi 7: What Changed & What Didn’t

WiFi 7 is the newest generation, and it does bring improvements:

• Higher potential speeds
• Lower latency
• Better performance for future devices

But here’s the critical point: WiFi 7 is an evolution, not a reset.

Most of the building infrastructure stays the same. The main change is the access points themselves.

“The only way to get WiFi 7 is to install WiFi 7 access points,” Todd explains. “Everything else is usually already there.”

Key takeaway: Good wiring makes upgrades simple. Bad wiring makes them expensive.

When Newer Isn’t Automatically Better

This is where WiFi upgrades often get misunderstood.

Think of WiFi upgrades like upgrading your iPhone.

Each new model is more powerful – but most people don’t upgrade the day it’s released. They wait until their current phone no longer fits how they use it, or when their current device in no longer functioning properly.

WiFi standards work the same way.  A newer version isn’t automatically better for your building – it’s better when the timing and use case align.

Do Existing Buildings Need to Upgrade to WiFi 7 Right Now?

In most cases, no.

Another way to think about it: installing WiFi 7 in many existing buildings is like driving a racecar to the grocery store.

The capability is impressive – but speed limits, traffic, and road conditions cap what you can actually use.

In many cases, a well-designed WiFi 6 network delivers a smooth, reliable experience that serves the property. If residents appear satisfied with their current internet connection, hold off on an upgrade from WiFi 6 to WiFi 7 until it can really deliver strong value.

WiFi 7 tends to make sense when:

• You’re developing new construction
• The project timeline is long
• The asset targets high-end or luxury positioning

WiFi 7 often adds limited value when:

• You’re upgrading an existing building
• Resident devices can’t yet use the added capability (Read: Which Devices Can Actually Use Wifi 7?)
• Budget would be better spent improving coverage and design

Key takeaway: Timing matters more than being first.

When Will WiFi 8 Come Out?

WiFi 8 is already being discussed – but it’s still years away from mainstream use.

When it does arrive, the pattern will be familiar:

• Incremental improvements
• New access points
• The same core lesson: design matters more than version numbers

From “Future-Proof” to Future-Ready

Nothing is truly future-proof.

“I prefer the term ‘future-flexible,’” Todd says. “You want to make upgrades easy, not disruptive.”

The most successful owners plan in phases:

• Install strong wiring and pathways
• Design networks with flexibility in mind
• Upgrade equipment only when it adds real value

Key takeaway: Future-ready decisions protect both budgets and options.

The Big Picture

WiFi evolution isn’t really about speed.

It’s about:

• Understanding what each standard actually does
• Designing buildings that support change
• Making upgrades intentionally – not reactively

For existing buildings, the takeaway is reassuring:

You don’t need to chase WiFi 7 to deliver a strong resident experience.

For new construction, the message is empowering:

If budgets and timelines allow, consider WiFi 7. But no matter the WiFi standard, prioritize a well-designed network. That will pay dividends for any tech upgrades down the road.

Good WiFi decisions aren’t about the newest version. They’re about making the right move at the right moment – and staying adaptable as technology continues to evolve.
