Office Wi-Fi Planning: Coverage, Capacity and Security

How to plan Wi-Fi for an office that works on day one — counting users and devices, placing access points, choosing Wi-Fi 6, 6E or 7, separating guests and devices, and testing before handover.

Office Wi-Fi fails for predictable reasons

Most office Wi-Fi complaints — calls dropping in the meeting room, slow uploads after lunch, the far cabin with no signal — come from the same few mistakes: one or two consumer routers for a whole floor, access points placed where the cable happened to end, everyone sharing one network with printers and cameras, and no testing after installation. Good planning avoids all of them.

Step 1: count people and devices

Plan for capacity, not just coverage. A typical employee now brings two or three Wi-Fi devices — a laptop, a phone and often a tablet or watch. Add meeting-room displays, printers, smart TVs, IP phones and any IoT devices. A 40-person office can easily have 120 devices, and video calls are the heaviest load.

  • Open work areas: plan roughly one AP for every 25–35 active users.
  • Meeting and training rooms: an AP in or right next to each large room.
  • Cabins and labs: check wall material — glass and drywall pass signal, concrete and brick do not.
  • Pantry, reception and terrace: often forgotten, always used.

Step 2: place access points from a survey

Ceiling-mounted APs in the middle of the area they serve give the most even coverage. Avoid mounting them inside metal false-ceiling cavities, above cable trays, or next to the lift and stair core. A predictive survey on the floor plan, followed by an on-site check, shows where signal is weak before the cabling is fixed.

More APs at lower power usually beats a few APs at full power: devices connect to the nearest AP, roam cleanly and do not fight for airtime.

Step 3: choose the Wi-Fi generation

In January 2026, India de-licensed the lower 6 GHz band (5925–6425 MHz) for low-power Wi-Fi, so 6E and Wi-Fi 7 access points can now use it here. Check that the exact AP model is approved for India and that most of your laptops support 6 GHz before paying a premium for it.

StandardBandsWhat it means for an office
Wi-Fi 6 (802.11ax)2.4 and 5 GHzHandles many devices efficiently; a solid baseline
Wi-Fi 6EAdds 6 GHzClean extra spectrum for newer laptops and phones
Wi-Fi 7 (802.11be)2.4, 5 and 6 GHzWider channels and multi-link operation; best for future-proofing

Step 4: separate networks

Run at least three wireless networks on separate VLANs: staff, guests, and devices. Guests should reach only the internet. Cameras, biometric machines, printers and smart TVs should sit on their own network so a compromised device cannot reach company laptops. A business firewall enforces these rules.

Step 5: cabling, PoE and power

Each AP needs one Cat6 (or Cat6A for Wi-Fi 7) cable back to a PoE switch in the network rack. Size the PoE budget for every AP, camera and phone at full load, and put the switch, firewall and ISP equipment on a UPS. A second internet line from a different provider, with automatic failover on the firewall, keeps the office working when one ISP goes down — common in Bangalore during road works.

Step 6: test and document

Before handover, walk every area testing signal strength, speed and roaming on a call. Record AP positions, switch ports, VLANs and admin passwords in a handover document, and change every default password. A Wi-Fi network that is documented can be fixed in minutes; one that is not usually ends up being replaced.

Quick answers

How many access points does a 5,000 sq ft office need?+

Often four to six, depending on walls, cabins and headcount. Meeting rooms and dense seating need more than open floor area suggests.

Should we buy Wi-Fi 7 now?+

For a new fit-out expected to last five years or more, Wi-Fi 7 is a reasonable choice if the budget allows. Wi-Fi 6 is still a solid, cost-effective baseline.

Can we use the ISP router for office Wi-Fi?+

For a handful of people, perhaps. Beyond that, use business access points and a firewall, and switch off the ISP router’s Wi-Fi.

Do you work after office hours?+

Yes. Cabling and cut-over can be scheduled for evenings or weekends to avoid disrupting work.
