Wi-Fi Solutions for Businesses

ACCL designs and installs business‑grade Wi‑Fi networks across London and the South East. We deliver reliable indoor and outdoor coverage, fast roaming, and secure segmentation, backed by a site survey, a documented install plan, and a clear handover pack so your IT team can support the network confidently.

Call 0333 900 0101 or email sales@network-data-cabling.co.uk to arrange a Wi‑Fi installation visit.

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

  • Best for: offices, schools, retail, hospitality and multi‑floor buildings with dead zones, unreliable roaming, or high device density.
  • Typical deliverables: survey findings, design plan, secure SSID/VLAN configuration, performance validation, and “as‑installed” documentation.
  • Outcome: consistent coverage, predictable performance for critical apps (VoIP, Teams/Zoom, POS), and fewer support tickets.

Wi‑Fi solutions we install

We install wireless networks that are sized for how you actually work — not a “one access point per floor” guess. Depending on the site and requirements, installations can include:

  • Indoor business Wi‑Fi for offices, schools, clinics, retail units and warehouses.
  • Outdoor Wi‑Fi for campuses, yards, terraces, car parks, event spaces and large venues.
  • Secure guest Wi‑Fi with isolation from corporate networks.
  • Staff Wi‑Fi with role‑based access, segmentation (VLANs) and modern encryption (e.g., WPA3 where supported).
  • High‑density Wi‑Fi for classrooms, lecture halls, conference rooms and hospitality venues.
  • Wi‑Fi backhaul options (wired where possible; point‑to‑point/mesh where needed) designed to protect throughput.
  • Access point installation with PoE switching and structured cabling to support stable power + performance.
  • Controller/cloud‑managed Wi‑Fi configuration (depending on your preferred platform) and admin handover.

When it’s time to upgrade your business Wi‑Fi

If any of the below sound familiar, it’s usually faster (and cheaper long‑term) to redesign the Wi‑Fi properly than to keep adding “extenders”:

  • Dead zones or unreliable signal in meeting rooms, corners, stairwells or high‑shelving areas.
  • Slow speeds at busy times (capacity issue), even though your broadband circuit tests well.
  • Devices that cling to the wrong access point (poor roaming) — common in multi‑floor offices and schools.
  • Frequent disconnects on video calls, VoIP handsets or Wi‑Fi calling.
  • Guest Wi‑Fi complaints impacting customer experience in hospitality/retail.
  • Security concerns: shared passwords, no separation between guests and staff, or no visibility of connected devices.
  • Office moves, refits, wall changes, racking changes, or new equipment increasing Wi‑Fi demand.

Our Wi-Fi installation Process

ACCL follows a survey‑led approach to prevent the most common Wi‑Fi mistakes (poor placement, interference, and undersized capacity). Here’s what to expect:

  • Initial call and requirements

    We confirm what “good Wi‑Fi” means for your site: building type, number of users/devices, critical applications (VoIP, video, POS), security requirements, and any constraints like out‑of‑hours working.

  • On‑site Wi‑Fi survey (or survey + design)

    We assess coverage, interference sources, cabling routes, mounting options and backhaul. For many sites, a formal Wi‑Fi site survey is the difference between “it works most of the time” and predictable performance.

  • Design and recommendations

    You receive a plan covering access point locations, expected coverage/capacity, SSIDs, security approach, and what needs to be installed (including cabling and PoE).

  • Cabling and PoE readiness

    Where required, we install structured cabling (typically Cat6/Cat6A) from comms rooms/cabinets to access point locations, and verify switching capacity/power budgets for PoE.

  • Professional installation and configuration

    We mount and commission access points, configure channels/power levels, SSIDs, VLANs and guest isolation, and align settings with your wider network policies.

  • Validation testing and optimisation

    We test performance where it matters (meeting rooms, classrooms, tills, high‑traffic areas) and tune the configuration to reduce co‑channel interference and roaming issues.

  • Handover and optional support

    We provide documentation and admin handover, and can support ongoing changes, expansion, or troubleshooting as your site evolves.

     

Indoor Wi‑Fi installations

Indoor environments are where Wi‑Fi expectations are highest — and where poor design shows up fast. Modern offices and public‑facing sites have more video calls, more cloud apps, and more devices per person than ever.

We design indoor Wi‑Fi to balance coverage and capacity. That means access points are positioned to reduce interference and improve roaming, not simply placed for “signal bars”. We also plan for real‑world constraints like dense walls, glass partitions, lift shafts, plant rooms and high‑EMI environments.

Outdoor Wi-Fi Installations

Outdoor Wi‑Fi needs different hardware, different mounting, and (usually) a better backhaul plan than indoor Wi‑Fi. Weatherproof access points, line‑of‑sight challenges, seasonal changes (foliage), and interference all matter.

ACCL installs outdoor Wi‑Fi for campuses, stadiums, leisure venues, hospitality terraces, yards and car parks. Where possible we use wired backhaul (fibre/copper) to protect throughput; where not, we design wireless backhaul carefully to avoid “too many hops” that reduce performance.

Security built into every Wi‑Fi deployment

Wi‑Fi is part of your attack surface. We build security in from day one — without making the network hard to use.

  • Modern encryption (e.g., WPA3 where compatible) and strong credential practices.
  • Network segmentation (VLANs) so guests and unmanaged devices cannot access business systems.
  • Optional 802.1X authentication for staff networks where required.
  • Firewall alignment and secure remote access practices for management interfaces.
  • Firmware/update guidance to reduce exposure to known vulnerabilities.
  • Documentation so future changes don’t accidentally weaken your security posture.

What you receive (deliverables)

Every Wi‑Fi installation should end with an “as‑left” pack — not guesswork. Depending on scope, your deliverables can include:

  • Access point placement plan (and post‑install “as‑installed” map).
  • SSID and network segmentation summary (guest vs staff, VLAN notes).
  • Configuration baseline (export/screenshot summary depending on platform).
  • Validation notes and performance checks for key areas.
  • Recommendations for next steps (coverage expansions, outdoor extensions, switching upgrades, or cabling improvements).

Challenges we address

While similar to indoor systems, outdoor networks have unique challenges that require expert installation. ACCL’s skilled installers ensure optimal performance by addressing these challenges:

Connection to the wired network: Outdoor networks need to connect to a nearby building. They ‘hop’ from one mesh access point to another before reaching the wired network. Each hop can reduce network speed, making careful design essential.

Avoiding interference: An on-site visit is crucial to identify sources of interference and find the best positions for access points, ensuring optimal connectivity.

Preventing over-compensation: Adding too many access points can impair performance. Our experts scale your system appropriately without overloading the access points.

Weather and seasonal changes: Weather conditions and seasonal changes, like tree growth, must be considered during installation to ensure consistent and reliable connectivity.

We use Advanced Security Measures in  Wi-Fi Installations to Protect Business Data.

When it comes to safeguarding your business data in Wi-Fi setups, several advanced security measures are employed to create a robust defence against cyber threats. Key techniques include:

  • Data Encryption: By encrypting data, sensitive information is transformed into a code, making it indecipherable to unauthorised users. This is typically achieved through sophisticated protocols like WPA3, ensuring that data remains secure as it travels across the network.
  • Firewalls: Acting as a barrier between your internal network and external traffic, firewalls closely monitor incoming and outgoing data. They block malicious attacks and unauthorised access, functioning as a crucial line of defence.
  • Secure Access Controls: These systems restrict who can access certain parts of the network, often using multi-factor authentication (MFA). By requiring additional credentials beyond just a password, MFA significantly reduces the risk of unauthorised access.
  • Automatic Updates and Patch Management: Regular updates to network hardware and software are essential. They protect against known vulnerabilities, ensuring that the network remains fortified against the latest threats.
  • Intrusion Detection Systems (IDS): By continuously monitoring network traffic, IDS identify unusual activities or anomalies that may suggest a breach. This allows for rapid response to potential threats, minimising damage.

Incorporating these measures into a professional Wi-Fi installation helps maintain the integrity of business data, providing peace of mind in an increasingly interconnected world.

FAQs

Q: Do I need a Wi‑Fi site survey before installing?

A: For most commercial sites, yes. A survey reveals interference, construction challenges and capacity needs, and prevents expensive re‑work. If you already have recent floor plans and a simple site, we can advise whether a lighter‑touch approach is appropriate.

Q: How many access points do I need?

A: It depends on floor area, layout, wall density, ceiling height, device count and performance requirements. We avoid rules‑of‑thumb and design based on survey data so you get predictable results.

Q: Can you install Wi‑Fi out of hours?

A: Yes. Many installations are scheduled around your operating hours to minimise disruption — especially in offices, schools and live retail/hospitality environments.

Q: Can you provide secure guest Wi‑Fi?

A: Yes. We can set up guest Wi‑Fi that is isolated from business systems, with appropriate bandwidth controls and policy settings based on your requirements.

Q: Will you install the cabling and PoE switching too?

A: Yes. ACCL can supply and install the structured cabling and PoE switching that access points require, and tidy/upgrade cabinets where needed for a clean, maintainable install.

Q: What’s the difference between Wi‑Fi 6, 6E and Wi‑Fi 7?

A: These are generations of Wi‑Fi standards. Newer generations can improve capacity, latency and spectrum options — but the right choice depends on your devices, applications and site constraints. We’ll recommend what’s appropriate and future‑proof where it makes commercial sense.

Q: Do you only work in London?

A: London is a core service area, and ACCL also supports organisations across Kent, Surrey and the surrounding areas. If you have multiple sites, we can plan a consistent rollout.

Q: Do you offer ongoing support after installation?

A: Yes. We can provide post‑install optimisation, troubleshooting, and planned upgrades as your site changes.
