Since 2001, NM Cabling has been delivering Wifi solutions for schools, network cabling, and fibre infrastructure projects across various educational environments. We began as the preferred supplier for the London Borough of Barnet, supporting over 130 primary, junior, secondary schools and colleges, and continue to work across the South East, South West and Home Counties today.
Our approach is infrastructure-first. In our experience, most school WiFi problems are not caused by access points, but by legacy cabling, insufficient fibre backbones, and poor network design. We focus on getting the foundations right, so wireless networks perform reliably now and remain fit for purpose in the years ahead.
We design and install Wi-Fi solutions for schools across all educational settings, including primary, secondary, and sixth-form schools, as well as multi-academy trusts.
While the principles of WiFi design remain consistent, each environment presents different challenges. Our designs are informed by professional on-site surveys and tailored to the site’s size, user count, and expected network demand.
Primary schools typically require full building coverage with predictable classroom usage, while secondary schools and colleges introduce higher device counts, more demanding applications and greater peak-time load. MAT environments often require consistency across sites, scalable backbone infrastructure and the ability to expand without re-engineering the network.
In every case, the design process considers WiFi coverage, capacity, switching, cabling standards and fibre connectivity as a complete system. When designing WiFi solutions for schools, every school is unique and thus requires a unique design.
We deliver end-to-end school WiFi infrastructure, either directly or in collaboration with trusted IT partners. This includes:
Wireless network design and access point deployment
Data cabling upgrades to modern standards
Fibre backbone installation between cabinets and buildings
Switching and cabinet remediation to support modern WiFi
Integration with existing school IT environments
We regularly work with platforms such as Cisco Meraki, Ruckus, Aruba and UniFi, remaining vendor-agnostic to ensure the solution is appropriate for the school’s budget, technical requirements and long-term plans. Each manufacturer has bespoke WiFi solutions for schools and colleges. While Meraki is often preferred, the final design is driven by suitability rather than brand.
Professional design is central to reliable WiFi. We conduct on-site predictive surveys and Ekahau heat-mapping to assess coverage, capacity, and interference across classrooms, halls, and shared spaces.
Older buildings, thick walls, temporary classrooms and listed sites are common in education. These are addressed during the survey stage, with designs adjusted to ensure consistent coverage and performance across the site.
All cabling, fibre, cabinets, switches and access points are installed by our own engineers, ensuring quality and accountability throughout the physical build. Configuration and system setup are completed in partnership with specialist IT providers where required.
To minimise disruption and maintain safeguarding standards, major installations are scheduled during school holidays wherever possible. Smaller works may be completed in term time where safe access is available and agreed with the school.
Our designs account for both coverage and capacity, ensuring WiFi performs reliably under real classroom conditions rather than just passing a basic signal test.
High-demand areas such as exam halls, sports halls, and shared learning spaces are treated as separate design challenges, with appropriate access-point density and network segmentation. Staff and guest access is planned alongside student usage to ensure performance and security are maintained across the entire site.
Acceptable classroom WiFi performance is defined by reliability and consistency, not headline speed figures. Networks are designed to support modern teaching methods, cloud platforms and assessment tools without degradation during lesson changeovers or peak usage periods.
Whole-site performance is achieved through correct access point placement, professional RF design and ensuring the underlying cabling and fibre infrastructure can support the wireless layer above it.
NM Cabling focuses on the installation and infrastructure side of WiFi solutions for school projects, working closely with specialist partners to provide ongoing management, monitoring and support where required.
Managed services typically include:
Continuous monitoring and alerting
Firmware and security updates
Proactive fault identification
On-site support when required
Service levels are tailored to each school’s requirements, with additional support capacity planned around exam periods and critical teaching windows.
Schools often engage us to upgrade the elements that limit WiFi performance, including:
Replacing legacy fibre with OM4 multi-mode fibre
Upgrading horizontal cabling to Cat6a
Installing access points supplied by schools or IT providers
Reworking cabinets to accommodate multi-gigabit switching
Removing and responsibly recycling obsolete equipment
By addressing these underlying issues, managed WiFi services become simpler, more stable and less reactive.
Safeguarding is approached from both a physical and network perspective.
All engineers are DBS checked, with risk assessments and method statements agreed in advance. Where possible, installation work is completed when schools are closed to minimise risk and disruption.
From a network perspective, WiFi designs support:
Separate student, staff and guest networks
VLAN segmentation and firewall controls
Integration with DfE-aligned filtering and monitoring platforms
Secure authentication for staff networks
Filtering and monitoring solutions are typically implemented by the school or its IT provider, with our infrastructure designed to support these requirements fully.
Safeguarding policies can be applied across both school-owned and BYOD devices using network segmentation and filtering platforms selected by the school. For MATs, policies can be centrally managed and consistently applied across multiple sites through ongoing support arrangements.
We have delivered infrastructure projects across large estates, including over 130 schools within the London Borough of Barnet.
We have also covered schools in multiple counties near our main office, including Bedfordshire, Hertfordshire, Buckinghamshire, and Middlesex.
Scalability is achieved by installing cabling and fibre that exceeds current requirements, following DfE guidelines, and allowing headroom for additional devices, buildings and future technologies. This approach avoids costly rip-and-replace upgrades as schools grow or join trusts.
New buildings, modular classrooms and site expansions are integrated into the existing network using fibre links and consistent WiFi design principles.
Peak usage periods are addressed through professional design rather than reactive fixes. Correct access point density, modern WiFi standards, network segmentation and adequate backbone capacity ensure performance remains stable during lesson starts, exams and whole-school online activity.
An initial survey and scope discussion is provided free of charge to assess requirements and outline options. More detailed Ekahau heat-mapping surveys and in-depth cabling or fibre audits are chargeable, but often incorporated into overall project pricing.
Following a survey, schools receive:
Clear findings on coverage, capacity and infrastructure
Budgetary and detailed pricing options
Recommendations for cabling, fibre and WiFi upgrades
Audits identify poor access point placement, capacity limitations, security considerations and cabling or fibre that does not meet modern standards.
The most common issue identified during audits is legacy cabling that cannot support modern multi-gigabit switching and access points. Schools are free to use the results of paid surveys independently, regardless of whether they proceed with installation works.
How much does school WiFi cost?
Pricing is bespoke and depends on the size, layout and construction of the school, existing infrastructure, access constraints and project timing.
Will installation cause disruption?
Major works are completed during school holidays. Limited maintenance tasks may be carried out in term time where safe access is available.
Who provides support if something goes wrong?
Each project is managed by a dedicated project manager and account manager, with UK-based support provided through agreed service arrangements.
