Wireless & Fixed Networks

Wireless & Fixed Networks for Schools & Public Sector

The secure, resilient network that keeps your security systems and your people connected — designed to carry CCTV, access control and alarms without compromise.

The Challenge

Security Systems Need a Network Built for Security

CCTV cameras, access control readers, door entry systems and intruder alarm panels are all network-connected devices. If the network they run on is congested, insecure or unreliable, your entire security infrastructure is compromised. A school whose CCTV drops offline because pupils are streaming video on the same network is not a secured school.

Fyrfly Systems designs and installs wireless & fixed network infrastructure that keeps security systems on their own dedicated, resilient network segment — while delivering high-performance connectivity for staff, pupils and visitors on separate, appropriately filtered networks.

Coverage Across Complex BuildingsMulti-storey schools, listed buildings, portable classrooms and large campus sites all present significant Wi-Fi coverage challenges that consumer-grade equipment cannot solve.
Securing Public Sector NetworksLocal authorities and NHS bodies must consider PSN connection compliance and cyber security baseline requirements when designing network infrastructure that carries sensitive data.
Legacy InfrastructureMany schools and public buildings have ageing wired infrastructure that cannot support modern IP security systems. We design wireless & fixed solutions that work around physical constraints.
Multiple User GroupsStaff, pupils, governors, visitors and contractors all need different levels of network access. A single flat network creates security and safeguarding risks that are easily avoided with proper design.

Infrastructure That Carries Everything — Securely

From access point survey and design through to installation, configuration and ongoing support, we deliver wireless & fixed network infrastructure built for the demands of education and public sector environments.

Wireless Access Point Design & Installation
Core Service · Foundation of Everything

Site survey, access point placement design and professional installation of enterprise-grade Wi-Fi 6 infrastructure that delivers consistent coverage across every area of your building — including the difficult spots: corridors, stairwells, mobile classrooms and large open areas like sports halls and assembly spaces.

  • Professional RF site survey before any hardware is specified
  • Wi-Fi 6 (802.11ax) access points for high-density environments
  • Ceiling, wall and outdoor access point options
  • Power over Ethernet (PoE) to minimise cable runs
  • Centralised wireless controller for unified management
Network Segmentation & VLANs
Security Essential

VLAN design that separates your security systems, staff network, pupil or public Wi-Fi and guest access onto isolated network segments — so that a compromised device on the public network cannot reach your CCTV or access control systems.

  • Dedicated VLAN for security systems (CCTV, access control, alarms)
  • Separate staff and pupil/visitor SSIDs with appropriate filtering
  • Firewall rules between segments to prevent lateral movement
  • Guest portal for visitor and contractor Wi-Fi access
Resilient & Failover Design
High Availability

Dual-WAN and 4G/5G failover configurations ensure your security systems stay connected even if your primary internet connection fails. For schools and public buildings where CCTV and access control are mission-critical, single points of failure are engineered out.

  • Dual-WAN routing with automatic failover
  • 4G/5G cellular backup for primary link failure
  • Redundant switching for core infrastructure
  • Monitoring and alerting for link status
Content Filtering & Safeguarding
Education Requirement

Schools are legally required to filter internet access for pupils under the Filtering and Monitoring Standards. We configure and manage content filtering solutions that meet DfE requirements across your entire wireless & fixed data estate — including any BYOD devices connecting to your school network.

  • DNS and deep packet inspection filtering
  • Category-based filtering aligned to DfE Filtering Standards
  • Age-appropriate filtering for different user groups
  • Monitoring and reporting for safeguarding compliance
Network Management & Support
Ongoing Service

Proactive network monitoring, firmware management and responsive support ensure your infrastructure performs consistently. We monitor access point health, bandwidth utilisation and security events — addressing issues before they become problems for your staff or your security systems.

  • 24/7 network monitoring with automated alerting
  • Scheduled firmware and security patch management
  • Monthly performance and utilisation reports
  • Priority support with agreed response SLAs
DfE Filtering and Monitoring Standards
Schools must have appropriate filtering and monitoring in place as a condition of funding. We design networks that meet the DfE's Filtering and Monitoring Standards and support Keeping Children Safe in Education obligations.
PSN Connection Compliance Considerations
Public sector networks connecting to the Public Services Network (PSN) must meet NCSC and Cabinet Office security requirements. We design infrastructure with these requirements in mind and work with your IT team and PSN assessor.
Cyber Essentials & NCSC Guidance
Network segmentation, access control, patching and monitoring are all Cyber Essentials requirements. Our network designs support your Cyber Essentials certification by implementing the technical controls the scheme requires.
UK GDPR — Data in Transit Security
Personal data transmitted over wireless & fixed networks must be appropriately secured. We configure WPA3 encryption, certificate-based authentication and network segmentation to protect data in transit across your wireless & fixed infrastructure.
Compliance & Standards

Networks Built for Public Sector Compliance

From DfE filtering requirements to PSN compliance considerations, we design networks that support your regulatory obligations — not just your connectivity needs.

Why Fyrfly for Wireless & Fixed Networks

The Foundation Everything Else Depends On

Your CCTV, access control and alarm systems are only as reliable as the network they run on. We design networks that treat security infrastructure as the priority — not an afterthought.

01
Security Systems First

We design your network around the needs of your security infrastructure. IP cameras, access control panels and alarm communicators all have specific bandwidth and latency requirements — we size and segment the network to guarantee they're met.

02
One Provider for Network and Security

When the same team designs and installs your network and your security systems, integration is seamless. No finger-pointing between contractors when a CCTV camera can't reach the NVR — we designed the whole thing, so we fix the whole thing.

03
Designed for Real Buildings

Victorian school buildings with thick walls, NHS corridors with lead shielding, temporary classrooms and outdoor spaces — we survey every environment before specifying a single access point, because a desk design never survives first contact with the building.
