In brief: Radio frequency spectrum fees are a regulatory cost that SA telecoms businesses using wireless infrastructure need to manage carefully. Understanding ICASA’s spectrum fee structure — and how it applies to fixed wireless, microwave links, and WiFi — helps resellers advise clients correctly and budget accurately.
Why Spectrum Fees Matter for SA Telecoms
Radio frequency (RF) spectrum is the invisible infrastructure underlying all wireless communications — mobile networks, WiFi, fixed wireless broadband, microwave links, satellite, and Bluetooth all rely on specific frequency bands allocated by national regulators. In South Africa, ICASA manages spectrum allocation and charges annual spectrum fees to licensed users of specific frequency bands.
For telecoms businesses and resellers, spectrum fees are a legitimate operating cost that needs to be included in business plans and client proposals wherever radio frequency communications are involved. Failure to obtain the necessary spectrum licences — or failure to pay spectrum fees — constitutes a regulatory offence under the Electronic Communications Act with potential fines and licence revocation as consequences.
ICASA’s Spectrum Fee Structure
ICASA’s spectrum fees are specified in regulations published under the Radio Act and the Electronic Communications Act, and are updated periodically to reflect inflation adjustments and policy changes. The fee structure is complex, with different rates applying to:
Frequency band: Different spectrum bands have different economic value and are priced accordingly. High-demand bands like 700MHz, 800MHz, and 2600MHz (used by mobile networks) command significantly higher fees than less congested bands. The 5GHz band used by many fixed wireless providers is typically licensed at lower fees due to its unlicensed or lightly licensed status in some applications.
Geographical coverage area: Spectrum licences are typically issued for specific geographic areas. A licence covering a national footprint is priced significantly higher than one covering a single metropolitan area or provincial region. Regional ISPs and WISPs like Herotel obtain geographically limited licences that match their service areas.
Bandwidth allocation: The width of the frequency channel allocated (measured in MHz) affects the fee. A 20MHz channel allocation in a given band will cost more than a 5MHz allocation in the same band.
Operator category: Licensed ECNS operators (those running physical network infrastructure) pay spectrum fees directly to ICASA. ECS-only operators who use leased infrastructure from ECNS operators do not typically pay spectrum fees directly — these are embedded in the wholesale prices charged by the infrastructure provider.
Spectrum Categories Relevant to SA Resellers
Unlicensed bands (ISM bands): The 2.4GHz and 5GHz WiFi bands are unlicensed in South Africa — equipment operating in these bands doesn’t require a spectrum licence from ICASA, though the equipment itself must be type-approved by ICASA for import and use in SA. Most office WiFi, small fixed wireless access deployments, and consumer equipment operate in these unlicensed bands.
Licensed fixed wireless access: WISPs deploying higher-powered fixed wireless networks at longer ranges (Herotel’s style of deployment across semi-rural areas) typically use licensed spectrum bands to avoid interference and achieve better coverage. Their spectrum licences are a significant operating cost embedded in their wholesale pricing.
Point-to-point microwave links: Many SA businesses and resellers use licensed microwave links to connect buildings or provide backhaul between network nodes. These links require individual spectrum licences from ICASA specifying the frequency, geographic coordinates, and transmit power.
5G spectrum: ICASA conducted a major 5G spectrum auction in 2022, allocating licences to Vodacom, MTN, Telkom, and Rain in the 3.5GHz band. These licences came with significant spectrum fees and coverage obligations that are driving the 5G rollout in SA metros.
Spectrum Fee Budget Planning
For telecoms businesses (ISPs, WISPs, network operators) that hold spectrum licences directly, annual spectrum fees need to be budgeted carefully. ICASA’s fee tables are published in the Government Gazette and should be reviewed annually when ICASA publishes revised fee schedules.
For telecoms resellers who don’t hold spectrum licences directly, the practical implication is understanding that spectrum costs are embedded in the pricing from licensed infrastructure providers. When a WISP like Herotel quotes for connectivity services, their pricing reflects spectrum licence costs, site lease costs, and other infrastructure expenses. Understanding this cost structure helps resellers have informed conversations about connectivity pricing with clients.
ICASA’s Spectrum Monitoring and Enforcement
ICASA operates spectrum monitoring infrastructure to detect unlicensed spectrum use. In populated areas, illegal radio transmitters are typically identified within days to weeks of operation. Consequences for operating unlicensed radio equipment include confiscation of equipment, fines, and criminal charges under the Radio Act.
For resellers advising clients who are deploying wireless networks (building-to-building links, campus wireless, IoT sensor networks), confirming that the planned deployment operates in unlicensed bands or that appropriate licences have been obtained is essential due diligence.
What This Means for SA Telecoms Resellers
Most telecoms resellers don’t deal with spectrum licensing directly, but understanding the regulatory framework helps you advise clients correctly and recognise when a proposed deployment requires specialist regulatory input.
If a client asks about deploying a point-to-point wireless link between two buildings, or deploying a fixed wireless broadband service to a rural farm, or using a non-standard radio system for industrial communications — these scenarios may require spectrum licences, and directing the client to the appropriate ICASA channels or a specialist telecoms regulatory consultant is the responsible response. The alternative — assuming everything is fine without checking — exposes both the client and your professional reputation to regulatory risk.
