When to redesign your Wi-Fi

Signs your business Wi-Fi needs an upgrade.

If these sound familiar, it is usually faster, and cheaper in the long run, to redesign the Wi-Fi properly than to keep adding extenders.

  • Dead zonesWeak or no signal in meeting rooms, corners, stairwells or high-shelving areas. See our guide to Wi-Fi black spots.
  • Slow at busy timesA capacity problem, even though your broadband circuit tests well.
  • Poor roamingDevices that cling to the wrong access point, common in multi-floor offices and schools.
  • Dropped callsFrequent disconnects on video calls, VoIP handsets or Wi-Fi calling.
  • Guest complaintsGuest Wi-Fi problems that affect customers in hospitality and retail.
  • Security gapsShared passwords, no separation between guests and staff, or no view of connected devices.
  • Moves and refitsOffice moves, wall or racking changes and new equipment that raise Wi-Fi demand.

Our Wi-Fi installation process

From first call to handover.

A survey-led approach avoids the common mistakes: poor access point placement, interference, weak roaming and undersized capacity.

  1. Initial call and requirements

    We confirm what good Wi-Fi means for your site: building type, users and devices, critical applications, security and access constraints.

  2. On-site Wi-Fi survey

    We assess coverage, interference, signal quality, cabling routes, mounting options and backhaul, so dead zones and rework are avoided.

  3. Design and recommendations

    A design plan covering access point locations, expected coverage and capacity, SSIDs, security, cabling and PoE needs.

  4. Cabling and PoE readiness

    Where needed we install Cat6 or Cat6A from the cabinet to each access point and check switch capacity and PoE power budgets.

  5. Installation and configuration

    We mount and commission access points and set channels, power levels, SSIDs, VLANs and guest isolation to your network policies.

  6. Validation and tuning

    We test coverage, roaming and performance in meeting rooms, classrooms, tills and known problem zones, then tune before handover.

  7. Handover and support

    Documentation and admin handover, with optional optimisation, troubleshooting and planned upgrades after go-live.

  8. Planning for growth

    We note where future access points, cabling, fibre routes or capacity upgrades may be needed as the site changes.

Secure by design

Secure wireless networks, planned in from day one.

Wi-Fi is part of your attack surface, so security is set up during the installation, not added later. We configure business-grade Wi-Fi to protect company data, separate users and devices, and reduce the risk of unauthorised access.

For larger or more sensitive sites we can support 802.1X authentication, role-based access and monitoring as part of the wider design. The aim is a network your IT team can manage with confidence, with clear documentation and no unknown configuration.

  • Encryption and separationWPA3 where supported, secure guest Wi-Fi, and staff and visitor networks separated with VLANs where required.
  • Aligned with your firewallWireless access rules that support your existing security policies, and secure management access to access points, controllers and cloud platforms.
  • Kept up to dateFirmware update guidance and documented configuration notes, so later changes do not weaken security.

What you receive

Your Wi-Fi handover pack.

Every installation ends with an as-left pack, not guesswork. Depending on scope it can include:

  • Placement plan and mapThe access point placement plan and an as-installed wireless network map.
  • Segmentation summarySSIDs and network segmentation, guest and staff, with VLAN notes.
  • Configuration baselineAn export or screenshot summary, depending on the platform.
  • Validation notesSignal checks and performance tests for the key areas.
  • Next stepsRecommendations for coverage expansion, outdoor extensions, switching upgrades or cabling improvements.

Business Wi-Fi explained

Commercial Wi-Fi installation, in depth.

Commercial Wi-Fi installation at a glance

A professional Wi-Fi installation is the end-to-end process of surveying your site, designing access point placement and capacity, installing the cabling and PoE it needs, configuring security and roaming, and proving performance with real-world tests.

It suits offices, schools, retail, hospitality and multi-floor buildings with dead zones, unreliable roaming or many devices. Typical deliverables are the survey findings, a wireless design plan, secure SSID and VLAN set-up, performance validation and as-installed documentation. The outcome is consistent coverage, predictable performance for VoIP, Teams, Zoom and POS, and fewer Wi-Fi support tickets.

Why businesses choose ACCL for Wi-Fi

ACCL delivers commercial network infrastructure for offices, education, retail, hospitality, healthcare and multi-site organisations across London and the South East. Because we deliver both structured data cabling and wireless, the installation is coordinated as one system rather than a collection of access points.

We look at the wider environment: cabling routes, PoE readiness, cabinet capacity, device density, guest access, roaming and future growth. Recent infrastructure work includes The Writer’s seven-floor upgrade, with seven cabinets moved in one controlled out-of-hours migration, and Verizon Business’s Holborn hub, with 358 Cat6A outlets and rooftop Private 5G.

Business network installers, not just Wi-Fi fitters

Wi-Fi only performs as well as the network behind it. As business network installers, ACCL handles the whole path: structured cabling from the cabinet to each access point, PoE switching, fibre between floors or buildings where needed, and the access points themselves. Because one team designs, cables, installs and tests it, faults are not passed between contractors, and the handover pack covers the cabling and the wireless together.

What affects business Wi-Fi performance

Strong Wi-Fi is not just more access points. Performance depends on building layout, wall density, ceiling height, device numbers, interference, roaming settings, cabling quality, switch capacity and how critical applications use the network. A meeting room with video calls and screen sharing needs a different design from a warehouse aisle, a classroom, a hotel terrace or a till area.

So we consider coverage, capacity and connectivity together. Coverage lets users connect. Capacity lets the network carry the number of devices using it. Connectivity means access points have suitable cabling, switching and backhaul behind them, so the infrastructure does not limit the Wi-Fi. Our guides to effective Wi-Fi installation and the top 10 business Wi-Fi installation mistakes go further.

Indoor Wi-Fi design

Indoors is where Wi-Fi expectations are highest and where poor design shows up fast. Offices and public-facing sites now carry more video calls, cloud apps and devices per person than ever.

We position access points to reduce interference and improve roaming, not for signal bars alone, and plan for dense walls, glass partitions, lift shafts, plant rooms and high-EMI areas. For layout advice, see office Wi-Fi and our guide to Wi-Fi site surveys.

Outdoor commercial Wi-Fi installations

Outdoor Wi-Fi needs different hardware, mounting and backhaul from indoor Wi-Fi. Weatherproof access points, line of sight, interference, seasonal foliage and mounting positions all affect performance. We install outdoor coverage for campuses, stadiums, leisure venues, hospitality terraces, yards, car parks and large commercial sites.

Where possible we use wired backhaul over fibre or copper cabling to protect throughput. Where a cable is not practical, we design wireless backhaul and mesh links carefully to limit hops and keep performance up.

Wi-Fi 6, Wi-Fi 6E and Wi-Fi 7

These are generations of the Wi-Fi standard. Newer generations can improve capacity, latency and available spectrum, but the right choice depends on your devices, applications, building and budget. A survey and a look at the devices you actually use tell us whether a newer standard is worth it now, or whether the cabling and switching should simply be made ready for it.

Business Wi-Fi by building type

Each building type has its own demands. See our pages for schools and colleges, banks and financial institutions, retail and shopping centres and warehouses and distribution centres, or browse all industry-specific Wi-Fi installations. For larger estates and multi-site rollouts, see corporate wireless solutions.

What affects Wi-Fi installation cost

Cost depends on floor area, layout, wall construction, the number of users and devices, whether new cabling and PoE switching are needed, outdoor areas, working hours, access and the level of testing and documentation.

For a rough figure, try the Wi-Fi cost calculator, and check switching capacity for access points with the network switch capacity calculator. For an accurate quote we usually start with a short discovery call and, where it helps, an on-site survey.

Before you book

Wi-Fi installation FAQs

How much does business Wi-Fi installation cost?

It depends on the floor area, layout, wall construction, user and device numbers, whether new cabling and PoE switching are needed, any outdoor areas and working hours. We do not quote a fixed price without that detail. Try our Wi-Fi cost calculator for a rough figure, then book a free site survey and we will send an itemised quote before work starts.

How long does a commercial Wi-Fi installation take?

It depends on the site, the cabling needed and access. As examples from our case studies, Gard’s 22 Cat6A links to 11 access points were installed and certified in one weekend, Tidraw’s office network took about ten days, and Southampton FC’s upgrade ran as a six-week close-season programme. We agree the timetable after the survey.

Do I need a Wi-Fi site survey before installing?

For most commercial sites, yes. A survey shows interference, construction challenges and capacity needs before access point positions are fixed, which avoids dead zones and rework. For a simple site with current floor plans, we can advise whether a lighter assessment is enough. See our Wi-Fi site surveys page for what a survey covers.

How many wireless access points will I need?

It depends on the floor area, layout, wall construction, ceiling height, device density and performance needs. We design from the survey findings rather than a fixed access-points-per-floor rule. A busy meeting floor or classroom block can need far more access points than an open office of the same size, so the count follows how the space is used.

Do you install the cabling and PoE switching as well?

Yes. ACCL installs the structured cabling, usually Cat6 or Cat6A, and the PoE switching the access points need, including cabinet work where required for a clean, maintainable installation. We check switch capacity and PoE power budgets so every access point has stable connectivity and power, and we test the links before the Wi-Fi goes live.

Can you install business Wi-Fi outside normal working hours?

Yes. Where needed, the installation is planned around your operating hours to reduce disruption in offices, schools, retail and hospitality sites. Cabling, access point mounting and cut-over can run in evenings or at weekends, and we agree the timetable, access and any noisy work with you or your building manager before we start on site.

Can ACCL provide secure guest Wi-Fi?

Yes. Guest access is isolated from your business systems, with suitable authentication, bandwidth and policy controls for your organisation. Staff networks can use role-based access, VLAN segmentation and WPA3 where supported, and we document the set-up so your IT team can manage guest and staff access confidently after handover.

Do you only provide Wi-Fi installation in London?

No. London is our core service area, with offices at the Royal Exchange and in Orpington, and we also support organisations across Kent, Surrey and the surrounding areas. That includes coordinated Wi-Fi rollouts for multiple sites, with the same survey, design, installation and handover approach at each location.

Do you offer support after installation?

Yes. After go-live ACCL can provide optimisation, troubleshooting and planned wireless network upgrades as your site and needs change. Because you receive an as-installed map, configuration notes and validation results at handover, later changes such as extra access points or outdoor coverage start from accurate records rather than guesswork.
