Wi-Fi for Coworking Spaces

In a café, Wi-Fi is an amenity. In a coworking space it's part of what's being sold, and that changes nearly every technical decision.

The difference shows in how people react when something breaks. A café guest with slow internet closes the laptop and enjoys the coffee. A coworking member whose call drops doesn't complain to you, they say nothing, then don't renew next month.

Size it by calls, not by seats

The most common mistake is multiplying seat count by some figure. Coworking has one load that no other venue carries: simultaneous video calls, all working day.

How to estimate: count how many might be on calls at the same moment. A third of capacity is a reasonable figure for an ordinary working day.

• 30 seats: assume 10 simultaneous calls → about 40 Mbps symmetric for that alone, so take 100 Mbps.
• 60 seats: 20 simultaneous calls → about 80 Mbps symmetric, so take 200 Mbps.
• Over 100 seats: start considering a business line with a guaranteed repair window, not merely a speed figure.

Separating tenants

This is the question corporate prospects ask most, and the answer determines whether you can take them at all.

Individual members

One shared network is adequate, on one condition: client isolation enabled. Without it, every member can see other members' devices, laptops, phones, open file shares. In a room full of strangers, that isn't acceptable.

Companies renting private rooms

Once a tenant brings their own equipment, printers, file storage, sometimes a small server, a shared network no longer suffices. What they need is their own network space, and that means VLANs.

The concept is explained in the guide to VLANs. What to watch when setting them up: each VLAN needs its own network name or its own switch ports, and a switch that supports them, see the guide to choosing a network switch.

The management network

Separate from both, and often forgotten. Point-of-sale machines, cameras, door locks, and staff computers must not sit on the same network as members. The principle is the same as in the guide to separating guest networks, only with higher stakes.

Access points and placement

Coworking has a problem ordinary offices rarely face: density. Forty people in one open room demands a different approach from forty people spread across several rooms.

• Many low-power access points, not a few powerful ones. An access point that's too strong makes devices across the room cling to it instead of moving to a nearer one.
• One access point per 20–25 active devices as a starting figure, rather than per so many square metres.
• Run cable to every access point. One linked wirelessly halves the available capacity, and at high density that's felt immediately, see the guide to choosing LAN cable.
• Favour 5 GHz, keeping 2.4 GHz only as a fallback for older devices, see the guide to 2.4, 5 and 6 GHz.
• Provide wired ports in private rooms. Corporate tenants often ask, and it reduces wireless load at the same time.

More detailed capacity planning is in the guide to venue Wi-Fi capacity, and placement in the guide to router placement. For multi-floor or long spaces, mesh considerations are in the guide to mesh versus repeaters.

Sharing capacity fairly

One member uploading a 200 GB backup can make the whole room stutter. This isn't malice, their device does it on its own, often without the owner noticing.

What works:

What's not advisable: cutting off heavy users. In a place paid for monthly, that produces disputes far more expensive than the capacity saved.

Backup connections

In coworking, an outage isn't a disruption, it stops the entire reason people pay. One full day without a connection is enough to lose several members.

What matters when arranging a backup:

• A different provider, and where possible a different physical route. Two subscriptions from the same provider fail together when the same trench cuts the same cable.
• Automatic failover, not manual. A backup that needs someone to switch it on fails exactly when it's needed.
• Test it regularly. Pull the main line once a month outside busy hours. A backup that's never tested nearly always disappoints the first time it's used.
• A 4G device as a third layer for meeting rooms, if budget allows, see the guide to MiFi and 4G routers.

Power is part of this too: a router that dies in an outage makes the backup line useless, see the guide to UPS for routers.

What prospective members always ask

Having the answers ready saves many conversations, and some of them decide the sale.

• "What's the speed?": quote the upload figure too, not just download. Prospects who know the difference will read it as a good sign.
• "Can our team have a separate network?": a yes opens the door to corporate tenants.
• "What happens if the internet goes down?": describe the backup. This is the question that most often decides.
• "Can we use wired?": for some work, cable isn't a luxury.
• "Is our traffic monitored?": answer honestly, and write the policy down. The obligations are covered in the guide to log retention duties.

What to check regularly

A coworking network ages faster than an office one, because the device count changes daily.

• Speed test at peak, not first thing in the morning.
• Review the device list: a count well above your membership means someone outside is using it, see the guide to seeing who's on your Wi-Fi.
• Change the member network password when memberships end, not once a year, see the guide to changing the Wi-Fi password.
• Update access point firmware, and check temperatures, see the guide to router overheating.

Size from simultaneous video calls rather than seat count, and make sure the upload path matches the download. That single decision determines the most.

The rest: client isolation for individual members, VLANs for tenants bringing their own kit, a separate network for management, and a backup line from a different provider that has actually been tested. In a place selling the ability to work, that isn't a premium, it's the baseline.
