Electrical Engineering · Structured Cabling, Networks and Wi-Fi

Network and Wi-Fi infrastructure for prime London homes and workplaces

Every system a modern building depends on – audio-visual, lighting control, automation, CCTV, access control, the family's own devices – runs across one network. When that network is designed properly, nobody thinks about it again. When it is improvised from consumer equipment, it becomes the most complained-about system in the building, and the complaints usually arrive after decoration is complete and the remedies have become disruptive.

AVC designs, installs and supports network infrastructure as an engineering discipline: structured cabling in copper and fibre, enterprise switching, wireless designed from surveys rather than guesswork, and a managed network that can be monitored and maintained after handover. Reliable Wi-Fi is the visible result – but it begins in the containment, the cabling and the rack.

A professionally designed network combines structured cabling, enterprise-grade switching and surveyed wireless coverage so that every wired and wireless device in a building performs reliably. AVC Integrations designs, installs and supports this infrastructure for large homes and demanding commercial spaces across London, from cable containment and equipment racks through to managed Wi-Fi, network security and remote monitoring.

The starting point

The problem: wireless blamed for wired failures

Most poor Wi-Fi is not a wireless problem. It is a router placed wherever the broadband entered the building, too few access points asked to cover too much masonry, no cabled backbone between floors, and a tangle of consumer equipment with nobody responsible for it. London's housing stock makes this worse: solid brick and stone walls, steel frames from structural work, foil-backed insulation and underfloor heating all attenuate wireless signals in ways a single router was never going to overcome. The equipment is rarely the villain – the absence of design is.

The consequences appear at the worst moment. Video calls drop in the study, streaming stutters in the media room, the automation system responds slowly, and the CCTV footage is missing frames – all in a property where the finishes are complete and pulling new cables now means opening decorated walls. A network is infrastructure, and infrastructure is cheapest to get right while the building is still open.

How AVC works

The AVC approach: wired first, designed wireless second

We treat the cabled infrastructure as the foundation of everything wireless. Structured cabling in copper and optical fibre links every access point, television position, equipment location and riser back to a properly planned rack; enterprise switching moves traffic between them; and only then is Wi-Fi designed on top – access-point quantities and positions determined from a wireless survey and the building's construction, not from a marketing coverage claim. Where the project justifies it we design to current wireless standards, including Wi-Fi 6E and Wi-Fi 7, selected against the building and its devices rather than by default.

The network is then engineered as a managed system. Traffic is segmented so that household devices, guest access, staff systems, AV, CCTV and building controls each live in their own part of the network; security is designed in rather than added after an incident; and remote access and monitoring mean faults are often identified and resolved before anyone in the building has noticed them. Because AVC delivers the electrical scope on most of its projects, the containment, power and cooling that the network depends on are coordinated in the same design.

What we deliver

Scope of service

Network scope is tailored to each appointment – design only, or design through installation to managed support. It typically covers:

Cabling infrastructure

  • Structured cabling design in copper and optical fibre
  • Cable containment coordinated with the electrical design
  • Equipment-rack design, location planning and power provision
  • Patch panels, cable dressing and labelling to a documented standard
  • Testing and certification of every installed link
  • Spare capacity and routes for future systems, agreed at design stage

Network and Wi-Fi

  • Enterprise switching and managed network architecture
  • Wireless surveys and predictive wireless design
  • Access-point planning – positions agreed with the interior design
  • Wi-Fi 6E and Wi-Fi 7 where the project justifies it
  • Roaming performance across floors and gardens, subject to detailed design
  • Infrastructure for AV, automation, CCTV and access control

Security and management

  • Network segmentation with VLANs – household, guest, staff and building systems
  • Firewalling and network security design
  • VPN and secure remote access for the household and its advisers
  • Remote monitoring and proactive fault response
  • As-built documentation and configuration records

Interfaces, resolved

One network, many systems

A building network only earns its keep when every other technology package can rely on it. We coordinate the network design with the AV, automation, security and electrical scopes from the outset – so that access points land where ceilings allow, racks have the space, power and ventilation they need, and no system arrives on site expecting a connection that was never cabled.

  • Access-point positions agreed with lighting, joinery and ceiling designs before plasterboard closes
  • Rack locations planned with the architect for space, power, cooling and acoustic separation
  • Containment and cable routes resolved within the electrical design, not squeezed in after it
  • Dedicated provision for AV, automation, CCTV and access control agreed with each package
  • Riser and floor-penetration requirements coordinated with structure and fire strategy
  • Incoming broadband and diverse-connectivity requirements planned with providers early
  • Labelling, documentation and patching standards agreed so the system stays maintainable

Where this applies

Project types

Prime houses

whole-house networks through solid construction, basements and gardens – designed, not assumed

Apartments and penthouses

lateral spaces with concrete slabs and limited riser access, where cable routes decide the outcome

Offices and workplaces

high-end commercial environments where the network carries the business as well as the building

Refurbishments

upgrading improvised networks to engineered infrastructure with the least intrusion the building allows

Timing

Why early involvement matters

Cable routes, riser space and the rack location are all decided – knowingly or not – by the time a building is plastered. A network designed at concept stage travels through the building invisibly; one designed after decoration negotiates with every finished surface it meets. The cabling itself is a modest part of a project's cost, but its routes are among the first things construction closes off, and reopening them is the expensive version of the same work.

Early involvement also protects the other technology packages. AV, automation, CCTV and access control all assume network provision at specific points; when the network designer is at the table from developed design, those assumptions are checked against drawings rather than discovered on site. AVC joins projects at any stage, including live retrofits – but the earlier the network is designed, the less the building has to forgive.

Questions, answered

Frequently asked questions

Why is 'coverage' the wrong way to judge Wi-Fi?+

Because a network can show full signal everywhere and still perform badly. What matters is capacity – how many devices each access point can serve well at once – and roaming, the handover between access points as people move through the building. We design for both, which is why a properly engineered network uses more, smaller wireless cells rather than one powerful transmitter shouting through the walls.

How many access points does a house actually need?+

There is no standard answer, and any figure quoted before a survey is a guess. The quantity depends on the construction materials, the floor plan, how each space is used and how many devices it must serve – all of which are established through a wireless survey and predictive design. Two houses of identical floor area can need very different designs.

If Wi-Fi is good enough, why run cables at all?+

Because good Wi-Fi is built on cables. Every access point needs a wired connection back to the rack, and anything fixed and demanding – televisions, AV equipment, cameras, control processors – performs best wired, which also frees wireless capacity for the devices that genuinely need it. A wireless-only network is a network with its foundation missing.

Can family, guests and staff be kept on separate networks?+

Yes – this is standard practice on our projects, delivered through VLAN segmentation on one physical network. Guests receive internet access without visibility of the household's devices, staff systems are kept apart from family data, and building systems such as CCTV and automation sit in their own segments. The separations are designed and documented, not improvised.

What are Wi-Fi 6E and Wi-Fi 7 – and do I need them?+

They are the current generations of the Wi-Fi standard, adding access to additional radio spectrum and more efficient handling of busy networks. Whether a project needs them depends on the devices it will serve and how long the infrastructure is expected to last – a judgement we make at design stage. The honest answer is that cabling and access-point placement decide more of the experience than the standard printed on the box.

Can the network be monitored after handover?+

Yes. We configure managed networks for secure remote monitoring, so performance can be observed, faults diagnosed and most issues resolved without a site visit. On supported projects this is often invisible to the client – a component misbehaves, an alert is raised and the fix happens before anyone in the building experiences a problem.

Where should the equipment rack go?+

Somewhere planned, which is the point. A rack needs space, power, ventilation and acoustic separation from living areas, and it should be positioned where cable routes from across the building can reach it economically. Plant rooms, basements and dedicated comms cupboards all work when they are designed for the job; the under-stairs cupboard chosen on the last day of the project rarely does.

Can you improve an existing house without opening every wall?+

Usually, yes. We survey what cabling and routes already exist, reuse what is genuinely serviceable, and design the smallest set of new routes that delivers a reliable result – often through existing risers, voids and cupboards. Where a compromise is unavoidable we say so plainly, with the options and their consequences set out before any work begins.
