You all need a reality check.
1. The basic satellite delay is 500ms, RTT. Then add to that the possible terrestrial link delay and you easily get to 600 ms. This is a fact of the physics of the game, NOTHING you or anyone can do about it.
2. IF the hub that the service is running off is offshore anywhere else than local, then the added terrestrial delays back to SA could push the Latency higher than 600 ms.
3. The satellite service is based on a high throughput Intelsat service, which has 4 spot beams focussed over SA.
The exact quality of the service WILL depend on exactly where you are located in SA AND requires a case-by-case design to verify if the link performance is adequate at your location to meet the performance limits. IF that link budget check is not made before the installation is done and you just happen to lie on the edge of one of the coverage beams, you are in trouble from the outset with the standard small antenna and low power BUC typically installed as part of the standard package.
3a. The uplink capability is directly proportional to the size of the antenna and the output power of the BUC, The downlink capability is TOTALLY dependent on where the ISP selling the service has located his servers - if collocated with the hub, then not too bad but if fed all the way back from the hun to a local server farm in SA, they will NOT be able to deliver on their promises.
4. From what I can see, just about ALL the local ISPs offering this service are NOT equipped to undertake a proper analysis of a client's requirements, which means most of their clients are NOT going to be happy with the service.
5. The ONLY part of their campaign of even trying to call it a "fibre-like service" is the fact that the service offers similar Up- and Down- link capacities. But that is as far as it goes.
But then what hell do I know, I am apparently too old and stupid to be able to undertake these crucial design exercises
