Education Technology: How Telecommunications Supports Schools and Universities

The Connectivity Demands of Modern Education

The expectation placed on educational institution networks has shifted dramatically. A secondary school in 2025 must support simultaneous 4K video streaming for remote lessons, online examination platforms with strict bandwidth requirements, staff using Microsoft 365 and cloud-based MIS systems, pupil devices in BYOD or 1:1 programmes, and visitor WiFi — all while maintaining the filtering and monitoring required under Keeping Children Safe in Education (KCSIE) guidance.

Consumer or entry-level broadband connections, which many smaller schools still rely on, are structurally inadequate for these demands. Latency, contention and lack of SLAs create disruption during exams and critical remote sessions. The infrastructure question is now a safeguarding and operational continuity question, not just a technology preference.

Connectivity Options for Educational Institutions

Leased Lines

For secondary schools, sixth-form colleges, further education colleges and universities, a dedicated leased line is the appropriate baseline. Unlike broadband, a leased line is uncontended — the full bandwidth is reserved for the institution, with guaranteed upload and download speeds. Symmetric speeds from 100 Mbps to 10 Gbps are available depending on site requirements and budget.

Leased line pricing for educational institutions typically ranges from around £200–£800 per month depending on speed and location. Many institutions access connectivity through regional broadband consortia (such as JISC for HE/FE) which aggregate purchasing power for preferential rates.

FTTP Broadband

For smaller primary schools or sites where leased line costs are prohibitive, Full Fibre to the Premises (FTTP) broadband provides a significant step up from ADSL. Speeds up to 1 Gbps are available in many areas and the symmetric nature of full fibre helps with upload-heavy applications like video conferencing. FTTP does not carry the same SLA guarantees as a leased line, so is better suited as a secondary connection or for lower-demand sites.

SD-WAN for Multi-Site Institutions

Multi-academy trusts and universities with multiple campuses benefit from SD-WAN (Software-Defined Wide Area Network) which intelligently manages traffic across multiple connections, ensures application-aware routing (prioritising video conferencing over background sync) and provides centralised visibility across all sites from a single management plane.

Cybersecurity in Education: A Growing Target

The education sector is disproportionately targeted by cybercriminals. In 2023, the NCSC reported that 78% of further education colleges had experienced a significant cyber incident. Schools represent attractive targets because they hold sensitive personal data on children and staff, often have limited dedicated IT security resource and are dependent on continuous system availability for operations.

Filtering and Monitoring (Keeping Children Safe in Education)

Schools in England are required under KCSIE to have appropriate filtering and monitoring in place. This means blocking access to harmful and illegal content, monitoring for indicators of radicalisation or vulnerability, and ensuring monitoring does not create a false sense of security (i.e., it needs to be actively reviewed). The DfE's Filtering and Monitoring Standards, updated in 2023, provide a specific checklist schools should meet.

Ransomware in Education

Ransomware attacks on schools, colleges and universities have caused significant disruption — including loss of examination data, student records and financial information. Attacks on multi-academy trusts can affect multiple schools simultaneously. The NCSC's guidance for the education sector recommends offline backups, network segmentation, multi-factor authentication and regular patching as the core defensive controls.

Unified Communications in Education

Microsoft Teams in Schools

Microsoft Teams is now widely used in education for virtual lessons, staff communication, parent engagement and document collaboration. Education institutions benefit from Microsoft 365 Education licensing at significantly reduced rates. However, many schools have deployed Teams without the governance controls needed to prevent inappropriate sharing of pupil data or safeguarding breaches in unmonitored channels.

VoIP Phone Systems

Legacy analogue telephone systems are being replaced across the education sector as the PSTN switch-off (originally planned for 2025, now rolling through 2027) forces migration to digital telephony. VoIP systems offer significant cost savings and greater flexibility — calls between sites over the data network, integration with Microsoft Teams for staff and simple management of extensions as staffing changes.

Practical Recommendations for School IT Leaders

• Audit current connectivity against actual usage patterns — bandwidth monitoring tools show peak utilisation and where constraints exist
• If on ADSL or ageing VDSL, model the cost of a leased line against the operational disruption caused by connectivity failures
• Ensure filtering meets the DfE's Filtering and Monitoring Standards and that monitoring is actively reviewed
• Apply MFA to all staff Microsoft 365 accounts as a minimum — this is the single highest-impact control against account compromise
• Separate pupil device networks from staff networks using VLANs
• Test offline backup restoration — many schools discover backups are inadequate only during an incident
• Plan for PSTN switch-off if you have not already migrated to VoIP or Teams Calling
