Wi-Fi 6 for offices in Oman: what to plan before you buy access points

What Wi-Fi 6 actually improves

Wi-Fi 6 (802.11ax) is designed for places where many devices share the same access point. It schedules traffic more efficiently, so an office full of laptops, phones, printers and video calls slows down less than it does on older Wi-Fi 5 equipment.

It does not make a weak signal stronger. A badly placed access point on Wi-Fi 6 still gives poor coverage, so the planning matters more than the label on the box.

Start with a coverage and capacity plan

Count the people and devices in each area, note which areas have video calls or large file transfers, and check the building: concrete walls, glass, lifts and metal partitions all reduce signal. A site survey, or at least a floor plan with wall types, shows where access points should go.

Aim to place more access points at lower power rather than a few at maximum power. Closer access points give each device a stronger signal and a faster connection.

Cabling and PoE decide what the access points can do

Each access point needs a cable back to a switch, and most are powered over that cable by PoE. Check the PoE standard the access point requires, since some Wi-Fi 6 models need more power than the oldest PoE switches provide, and check the switch has enough total PoE budget.

• Use Cat6 or better cabling to each access point
• Check the switch port speed: some Wi-Fi 6 access points can use a multi-gigabit uplink
• Add up the PoE budget of every access point on the switch
• Keep cable runs within the 90 metre structured cabling limit

Separate staff, guest and device networks

Put staff, visitors and devices such as printers, cameras and IoT equipment on separate networks (VLANs), each with its own wireless name and rules. Guests then get internet access without reaching your servers, and a problem on one network stays on it.

Check the 6 GHz question before buying Wi-Fi 6E

Wi-Fi 6E adds the 6 GHz band, but the rules for using it differ between countries. Confirm what is permitted locally before paying extra for it, and make sure your devices actually support it.

Common mistakes

These are common mistakes in office Wi-Fi planning.

• Placing one access point in a corridor and expecting every room to be covered
• Buying on advertised speed instead of planning for the number of devices
• Putting every device on one flat network
• Forgetting to plan central management, so each access point is configured by hand
• Using old cabling that cannot carry the speed or power
