ICASA Spectrum Licence Fee Calculator
Get an instant estimate of your annual ICASA radio frequency spectrum licence fee for a point-to-point microwave link. Enter the GPS coordinates of both tower sites, pick your frequency band and bandwidth, and we work out the distance, area classification, and estimated fee for you.
How is the ICASA spectrum licence fee calculated?
Every licensed point-to-point microwave link in South Africa attracts an annual radio frequency spectrum licence fee from ICASA (the Independent Communications Authority of South Africa). The formula behind that fee is set out in ICASA's fee regulations and re-gazetted every year, and it isn't a single flat rate — it's built up from several factors specific to your link:
- Frequency band — which GHz band your link operates in (5 GHz through 38 GHz cover essentially every terrestrial point-to-point microwave link used by South African WISPs).
- Bandwidth / channel width — the MHz channel your radio uses, which must match a valid ICASA/ITU-R channel arrangement for that band.
- Link distance — the straight-line "hop" length between your two tower sites. Counter- intuitively, a hop shorter than ICASA's minimum expected path length for that band costs more, not less.
- Geographic area — whether the link falls inside a high-demand metro area (Gauteng Province, or the municipal areas of Cape Town and Durban) or everywhere else in South Africa.
- Congestion, spectrum sharing, and directionality — smaller adjustments depending on how the licensed spectrum is actually used.
Working all of that out by hand from ICASA's gazette tables takes time and is easy to get wrong. This is, as far as we're aware, the only free public calculator in South Africa that automates the entire ICASA spectrum licence fee formula — enter your two tower sites' GPS coordinates, your frequency band, and your bandwidth, and get an instant, accurate estimate.
Why South African WISPs need to get this right
Under-budgeting for ICASA spectrum licence fees is a common and avoidable compliance risk for wireless internet service providers (WISPs) and other licensed network operators. Getting the estimate wrong can throw off network expansion planning, licence renewal budgets, and even licence application timelines. WISPCOM manages ICASA compliance, licence applications, and annual reporting for WISPs across South Africa — this calculator is a free tool we built to help operators budget accurately before they come to us for a confirmed quote or a full licence application.
Frequently asked questions
How is the ICASA spectrum licence fee calculated?
ICASA charges an annual radio frequency spectrum licence fee for every licensed point-to-point microwave link. The fee is driven by several factors set out in ICASA's fee regulations: the frequency band the link operates in, the channel bandwidth, the link (hop) distance, whether the link falls in a high-demand metro area or a rural area, and whether the spectrum is shared, congested, or unidirectional. This calculator applies all of those factors automatically from just your GPS coordinates, band, and bandwidth.
Does my ICASA spectrum fee change every year?
Yes. ICASA re-gazettes the unit price per MHz every 1 April, adjusted for CPI inflation, so the same link typically costs slightly more each licence year.
Is a shorter microwave link cheaper to licence?
No — the opposite. ICASA sets a minimum expected path length for each frequency band. A hop shorter than that minimum attracts a premium on the licence fee rather than a discount.
Do ICASA fees differ between metro and rural links?
Yes. Links in high-demand metropolitan areas (Gauteng, Cape Town, and Durban) are priced differently to links everywhere else in South Africa. This calculator works that out automatically from your link's GPS coordinates.
Is the calculator result an official ICASA quote?
No. This tool gives a free, instant estimate based on the publicly gazetted formula. Your actual licence fee is confirmed by ICASA at application or renewal. Contact WISPCOM for a confirmed quote or help preparing your licence application.
Do I need an ICASA licence for a point-to-point microwave link at all?
Almost always, yes. Point-to-point microwave links used for telecommunications backhaul in South Africa operate on licensed spectrum, which requires an ICASA radio frequency spectrum licence and attracts this annual fee. Start a licence application or contact WISPCOM to confirm your specific requirements.
