Wi-Fi solutions for schools and campus networks
Wi-Fi solutions for schools are the cabling, switches, access points, firewall and content filtering that let every classroom, lab and office connect safely at the same time. Arke Technologies designs, installs, secures and supports school networks for independent and public schools, colleges and campuses across South Africa, from Johannesburg.
IT infrastructure for schools: what the network has to carry
A school network works harder than an office network of the same size. At 07:45 hundreds of learner devices sign in within minutes; the administration office runs SA-SAMS, fees and payroll on the same cables; and interactive displays stream video in classroom after classroom. The network has to absorb those peaks, keep each group apart and keep working when the power goes.
IT infrastructure for schools comes in layers, and any one of them can be the bottleneck:
- The line in. Business fibre, with fixed LTE as a second route.
- The edge. A firewall that filters content, separates networks and records what happened.
- The core and the cabling. Managed switches with VLANs, Cat6 to every access point, fibre between buildings.
- The Wi-Fi. Access points planned for the devices in each room, not only for coverage.
- Power. Power over Ethernet (PoE) switches and a UPS in each network cabinet, to ride through load-shedding.
- Management. Monitoring, documentation and one accountable team.
Our education IT overview shows how the network fits with devices, platforms and support.
Wi-Fi solutions for schools: design for classrooms, not corridors
The best Wi-Fi for schools is designed around capacity. A common rule of thumb for offices is one access point per 150 square metres, but a classroom of 35 learners working on devices at once needs its own access point, and a hall needs several. Face-brick walls, concrete slabs and prefabricated classrooms all change the plan, so we survey before we specify.
What we design in:
Wi-Fi 6 (802.11ax) or newer access points, which serve many devices at once far better than older standards.- PoE+ (802.3at) switches with at least a 20% margin on the power budget, because Wi-Fi 6 access points draw more power than older models.
- Overlapping coverage, so a failed access point or a firmware update does not leave a classroom offline.
- Central management from a cloud dashboard or an on-site controller. Where management carries a subscription, we check what the access points do if it lapses, because vendors differ.
- Roaming that follows a teacher's laptop from classroom to staff room.
We configure Fortinet, Sophos, MikroTik, Ubiquiti UniFi, TP-Link Omada and Cisco equipment. Hardware comes through our trading division Server Hub, configured and bench-tested before dispatch, with a local warranty on every unit. The wider design principles are on business Wi-Fi and wireless networks.
Campus network infrastructure: joining blocks, residences and sports fields
Wi-Fi solutions for campus sites add distance and scale. Copper cabling stops at 100 metres, so separate blocks, residences and sports facilities are joined with fibre. Fibre also isolates buildings electrically, which matters in Highveld storms, when a lightning surge travelling along copper between buildings can destroy the switches at both ends.
Campus network infrastructure is built in tiers: a core in the main server room, distribution switches in each building and access switches feeding the rooms. We add redundant links where one failure would take a block offline, and design residences for their evening load. Universities and TVET colleges have their own page: IT for universities, TVET colleges and training providers. Our team designs, installs, certifies and documents the cabling; see structured cabling.
Content filtering and online safety on the school network
The firewall is where a school decides what learners can reach. We filter by group, strictest for the Foundation Phase, lighter for Grade 12 and lighter again for staff; we enforce safe search, restrict video platforms to suitable content and block the proxy tools learners use to get around the rules. Where learners take school devices home, device policies can apply the same rules off the school network.
The firewall's logs are also evidence when a governing body investigates an incident, or the school must show how a security compromise happened. The wider picture is on cybersecurity, POPIA and online safety for schools and firewalls and network security.
Wireless internet for schools starts with the line in
Wireless internet for schools is only as good as the connection behind it. Our connectivity division, Fibre Boyz, has connected homes and businesses since 2017 and supplies uncapped business fibre and fixed LTE, connected, billed and supported by us: one bill, one number. A fixed-LTE line gives the school a second route when the fibre is cut, and bundled into a support contract, the line, the network and the help desk sit with one supplier. See business connectivity.
Governance, procurement and continuity
- SLA and reporting. The SLA fixes scope, exclusions and on-site policy, and is set to the school's needs. Incidents are prioritised from P1 (a critical outage) to P4 (a low-impact request), with response and resolution targets matched to the impact of downtime and agreed in your SLA. Each month you receive a service review and report on network health, faults and changes.
- Change control. Firewall rules, filtering categories and network changes are requested, approved and recorded, so the school knows who changed what, and why.
- POPIA and governance. Administration networks are isolated, logs kept for a defined period and equipment access limited to named people. King IV Principle 12 asks the governing body to govern technology and information; the monthly report gives it the record. See King IV technology governance.
- Procurement. Arke Technologies is a Level 1 B-BBEE contributor, giving 135% procurement recognition (sworn affidavit available on request). Company documents, a bank confirmation letter, our CSD number and tax compliance status are available on request, and we complete SBD forms when a bid requires them. We respond to a request for quotation or a tender, work on your purchase order, and keep the paperwork a governing body needs for the annual audit of school funds. Where a provincial education department is the buyer, we work to PFMA procurement and reporting disciplines. See company facts for procurement teams.
- Continuity. The equipment, configurations, documentation and credentials belong to the school, and we hand over cleanly if you move. A certified team works remote-first from Johannesburg and on site as your SLA sets out: one contract, one accountable team.
