South Africa's 5G story is no longer only about consumer smartphone coverage. A parallel industrial rollout is underway, and it is accelerating faster than most commercial property owners and business operators realise. MTN has confirmed it is building private 5G networks for 14 companies operating in the country's mining and port sectors, a deployment milestone that signals a fundamental shift in how large enterprises think about wireless connectivity.
For businesses outside heavy industry, this shift still carries significant implications. It changes what tenants will expect from commercial buildings, what regulators are opening up in the spectrum bands, and what physical infrastructure inside your property needs to support. This post unpacks each of those dimensions in practical terms.
Private 5G Networks Deliver Dedicated Capacity Where Public Networks Cannot
A private 5G network is a cellular network that operates in licensed or shared spectrum but is deployed exclusively for a single organisation or campus. Unlike public 5G, where a mine or factory competes for bandwidth with millions of other subscribers on the same carrier infrastructure, a private network reserves capacity entirely for the enterprise that operates it.
MTN's deployment of 14 private 5G networks for South African mining and port companies is the clearest local proof of this model at scale. These deployments are designed for industrial use cases where the limitations of public networks are unacceptable. Underground mine operations require continuous telemetry from autonomous drilling and haulage equipment. A dropped connection at 100 metres below surface cannot be tolerated the way a dropped video call on a smartphone can be.
The core use cases driving private 5G adoption break into three categories. First, autonomous equipment control: remote operation of mining machinery, port cranes, and automated guided vehicles relies on sub-10 millisecond round-trip latency that public 5G networks with shared backhaul cannot reliably deliver. Second, dense sensor networks: real-time environmental monitoring for gas levels, structural stability, and equipment temperatures generates continuous data streams that require guaranteed bandwidth. Third, high-definition video surveillance: port security and mine safety applications stream multiple simultaneous 4K feeds that saturate any Wi-Fi or public LTE link within weeks of deployment.
The distinction between private and public 5G is not merely technical. It is a procurement and licensing matter. Enterprises operating private networks must hold their own spectrum licence or operate under a shared spectrum arrangement, which is a regulatory process that CT Communications helps commercial clients navigate.
South Africa's 5G Spectrum Landscape Has Shifted Substantially Since 2022
The foundation for South Africa's 5G expansion was laid at the ICASA spectrum auction in March 2022. That auction raised USD 960 million in total proceeds, confirming the scale of operator appetite for licensed 5G spectrum. MTN committed approximately R5 billion for its spectrum allocation, while Cell C secured 10 MHz of capacity for R288.2 million. Vodacom made comparable commitments in adjacent bands.
The primary mid-band for 5G in South Africa is Band n78, centred on 3.5 GHz. This band offers the best balance between propagation range and capacity, which is why it is the global reference band for commercial 5G deployments. For operators, n78 spectrum allows them to cover urban areas with fewer base stations than high-band millimetre wave frequencies, while still delivering multi-hundred megabit throughput.
Beyond the 2022 auction allocations, ICASA has moved to open additional spectrum for dynamic use. The regulator published plans to make the 3800 to 4200 MHz and 5925 to 6425 MHz bands available under Dynamic Spectrum Access arrangements, where multiple users can share frequencies without interfering. This is significant for enterprise operators because it creates a pathway to private 5G deployment without requiring a full individual spectrum licence in some configurations.
Coverage metrics as of late 2024 show MTN at approximately 44 percent 5G population coverage and Vodacom surpassing 50 percent. The Broadcast Media Africa report on 2024 5G surge confirms that both operators were aggressively expanding their 5G footprints through the year, largely driven by growing enterprise demand for mobile private network (MPN) services.
| Spectrum Band | Frequency Range | Use Case |
|---|---|---|
| Band n78 (primary mid-band) | 3.5 GHz | Commercial 5G, urban coverage |
| Upper C-band | 3800 to 4200 MHz | Dynamic Spectrum Access, enterprise 5G |
| Lower 6 GHz | 5925 to 6425 MHz | Dynamic Spectrum Access, indoor 5G |
Real Deployments in Mining, Ports, and Logistics Are Generating Measurable Returns
MTN's confirmation of 14 active private 5G network deployments for mines and ports is not a pilot programme or a proof of concept. These are production networks carrying operational traffic for enterprises that have moved beyond evaluation and into daily dependency on private 5G infrastructure.
In mining, the primary value proposition is the replacement of wired Ethernet runs through tunnels and shafts with wireless connectivity that can serve equipment in motion. Autonomous drilling rigs and LHD (Load Haul Dump) vehicles require constant command and telemetry links. Traditional Wi-Fi 6 networks struggle with the metallic interference and physical geometry of underground environments. 5G in the 3.5 GHz band, with its superior non-line-of-sight propagation, handles these environments more reliably. Real-time gas sensor arrays and emergency communication systems also benefit from guaranteed Quality of Service features built into the 5G New Radio standard.
Port operations present a different but equally demanding environment. Vodacom has committed R20 billion to its overall 5G investment programme, with a significant portion directed at enterprise and port logistics applications. Port crane automation, container tracking via IoT transponders, and fleet management for terminal tractors all generate high-density, low-latency traffic that private networks handle without the congestion variability of public carrier connections.
Both MTN and Vodacom report growing enterprise demand for Mobile Private Networks, which are 5G deployments where the operator provides the spectrum and radio access network but the enterprise retains exclusive use of a dedicated slice or standalone network. This model allows companies to benefit from operator-grade infrastructure without the complexity of holding their own spectrum licence directly.
"Both MTN and Vodacom are reporting growing enterprise MPN demand as industrial customers move from evaluation to full production deployment on private 5G networks."
The Regulatory Path for Private Networks Requires Careful Planning
Operating a private 5G network in South Africa requires navigating several layers of licensing, and the regulatory framework is still evolving as ICASA adapts to enterprise demand.
The starting point is spectrum. Section 31(1) of the Electronic Communications Act requires any entity transmitting on licensed spectrum to hold a radio frequency spectrum licence issued by ICASA. For a business deploying its own 5G radio access equipment, this means applying directly to ICASA for a spectrum assignment in the relevant band. The ICASA spectrum licensing portal outlines the application process, which includes technical frequency coordination to avoid interference with existing licensees.
Beyond spectrum, the scope of the private network determines which Electronic Communications Network Service (ECNS) licence is required. A network that connects only to internal systems within a single property may qualify for a limited ECNS registration. A network that connects to the public switched network or spans multiple sites requires a full ECNS licence. Where the network forms part of a public electronic communications network, an Individual ECNS licence is necessary, and that licence category requires a Ministerial Policy Directive before ICASA can grant it, which adds a further regulatory step.
All radio frequency equipment used in the private network, including base stations, small cells, and user equipment, must carry ICASA type approval. Importing or deploying unapproved hardware is a contravention of the ECA regardless of the operator's licensing status.
The CMS Law guide to 5G regulation in South Africa notes that the country's regulatory framework for enterprise-owned private networks is still developing, and ICASA is expected to publish more specific guidance for industrial deployments. Businesses considering a private 5G project should engage a regulatory consultant early in the planning process to map the correct licence pathway before any capital is committed to radio hardware.
Commercial Property Infrastructure Needs to Be 5G-Ready Now
The industrial deployments described above are setting expectations that will flow into commercial office and mixed-use property within the next two to three years. Tenants who have experienced private 5G connectivity in a mining or logistics context will bring those expectations to their office space procurement decisions.
Two physical infrastructure elements determine whether a building can support 5G connectivity at the density tenants will require. The first is distributed antenna system or small cell readiness. 5G in the 3.5 GHz band has a shorter propagation range than 4G LTE at 1800 MHz. Buildings with large floor plates, reinforced concrete cores, or extensive glazing will need internal passive or active DAS infrastructure to distribute signal from a base station at the building boundary to the interior spaces where tenants work.
The second element is fiber backhaul capacity. A 5G small cell node consuming 2 to 4 Gbps of throughput at peak requires a fiber connection to the building's main distribution frame. Legacy Cat5e horizontal cabling cannot carry that load. Structured cabling installed to TIA-568-C.2 or ISO 11801 standards, using at minimum Cat6A to desk and OM4 multimode fiber between floors, is the baseline for a 5G-ready internal network.

Frequently Asked Questions
- Does a business need its own spectrum licence to benefit from 5G connectivity?
- Not necessarily. The most accessible route is through an operator-hosted Mobile Private Network, where MTN or Vodacom provides the spectrum and radio hardware while the enterprise receives a dedicated network slice. Businesses requiring full control over their network, typically in sensitive security or industrial environments, may choose to hold their own licence, which requires a direct ICASA spectrum application under Section 31(1) of the ECA.
- What is the difference between private 5G and a Wi-Fi 6 enterprise network?
- Wi-Fi 6 operates in unlicensed spectrum shared with neighbouring buildings, homes, and devices, which means interference and congestion are outside the operator's control. Private 5G uses licensed or coordinated spectrum, delivers guaranteed Quality of Service for latency-sensitive applications, supports mobility at higher speeds without handoff gaps, and offers superior penetration in dense concrete or metallic environments. For most office environments, Wi-Fi 6 remains practical, but for large campus sites, warehouses, or properties with high-mobility requirements, private 5G offers measurable performance advantages.
- How does a building owner prepare for private 5G without knowing which tenants will use it?
- The most practical approach is to install conduit pathways and fiber backhaul capacity to planned small cell mounting positions during any refurbishment or new build. This is significantly cheaper than retrospective civil work. A 5G readiness assessment from CT Communications identifies which floor plate positions, vertical risers, and roof access points need preparation so that small cell nodes can be installed at minimal cost when tenant demand materialises.
