Comsol Networks — wireless internet provider in South Africa
Comsol Networks (Pty) Ltd has been at the forefront of South African wireless connectivity since 1997 and operates from Koranna Avenue in Centurion. What separates it from most fixed wireless operators is the spectrum: Comsol uses licensed 28GHz mmWave and 3.7GHz bands rather than shared unlicensed airwaves, delivering 1Mbps to 1000Mbps across more than 200 metropolitan areas covering over 15,000 square kilometres of South Africa’s business districts.

Licensed spectrum is the whole proposition
Most fixed wireless in South Africa runs on unlicensed bands, which means your link shares the air with every other operator and every device nearby, and performance varies with what your neighbours are doing. Comsol states it uses licensed 28GHz mmWave and 3.7GHz spectrum, which is exclusive to the licence holder. That is the difference between a best-effort connection and something that behaves like a leased line, and it justifies a business-grade price where ordinary wireless would not. The 1Mbps to 1000Mbps range is unusually wide, so establish what is actually available at your building rather than assuming the top figure. Nearly thirty years of trading and a published coverage figure of 15,000 square kilometres make this a substantive operator rather than a reseller.

Who Comsol Networks is a fit for
- Businesses needing leased-line behaviour without waiting for a fibre trench

Ask what speed the licensed spectrum can actually deliver at your building, since the published range runs from 1Mbps to 1000Mbps. Say how many sites you have and where, what uptime your operation requires, and whether a private network rather than internet access is the real need.

What is licensed mmWave spectrum?
It is radio spectrum allocated exclusively to the licence holder, so the link is not competing with other operators or devices. That gives more predictable performance than unlicensed wireless, which is why it can behave more like a leased line.
How long has Comsol been operating?
The company states it has been at the forefront of wireless connectivity since 1997 and describes nearly thirty years of connecting South Africa.
Does Comsol cover my area?
The published claim is more than 200 metropolitan areas covering over 15,000 square kilometres of South Africa’s major business districts. Fixed wireless still needs a path to your building, so ask for an address-level check.
Does Comsol offer phone services?
No voice product is published. Comsol presents as a connectivity operator, so if you need business telephony, compare dedicated voice providers separately and treat this as the line underneath them.
Is Comsol ICASA licensed?
An ICASA logo is displayed and the company states it uses licensed spectrum, but no reference number is published. Because the spectrum claim is central to the offering, ask for the licence detail in writing.
What does it cost?
No pricing is published. Business wireless is priced by the link, the committed speed and what has to be installed at the site, so ask for installation and monthly charges as separate figures.
