Fibre alternatives: what to do when fibre isn’t in your area
Fibre is the gold standard, but it does not reach every business park, farm or new development. Business LTE, 5G fixed wireless, licensed microwave and satellite can all keep you online, and each suits a different location and budget.
What are the best alternatives to fibre for a business in South Africa?
When fibre is not available, the main business-grade alternatives are LTE and 5G fixed wireless, licensed point-to-point microwave, and satellite. LTE and 5G install in days and suit most offices; microwave delivers fibre-like reliability with a service-level agreement; satellite reaches truly remote sites. A hybrid setup with automatic failover keeps you online when any one link drops.
Why fibre might not reach you yet
Fibre coverage in South Africa is uneven, and the gaps are rarely about the technology.
A location can miss out because there is little existing infrastructure in remote or low-density areas, because municipal trenching and wayleave permissions are slow, or because rollout costs do not yet justify the build in a low-demand zone. If you sit in a commercial park or a shared building, it is worth asking neighbouring tenants to request a group installation, since aggregated demand sometimes moves a site up an operator’s build queue. While you wait, a wireless or satellite link keeps the business running.
Business LTE and 5G fixed wireless
For most offices, mobile-network fixed wireless is the quickest and simplest fibre substitute.
LTE and 5G have improved enough to run a business on. Providers offer business plans with uncapped data (subject to a fair-use policy), static IP options and failover, and installation is usually a matter of days rather than weeks because there is no trenching. The trade-offs are that throughput depends on signal strength and cell congestion, and latency is higher than fibre, which matters for real-time voice and video. A directional external antenna often lifts a marginal signal into a usable one.
5G fixed wireless, where the coverage exists, closes much of the gap: it can deliver fibre-like download speeds and latency in the region of 20 to 40 milliseconds, which is comfortable for hosted voice. LTE remains the more widely available of the two and is the natural interim link while you wait for fibre or 5G to reach you.
Licensed fixed wireless and microwave
When you need fibre-grade reliability without fibre, a licensed point-to-point link is the business answer.
A wireless internet service provider can install a dedicated microwave or licensed-spectrum link between your premises and a nearby tower or fibre point of presence. Unlike consumer LTE, these are sold with a service-level agreement, symmetrical speeds and dedicated (not contended) bandwidth, so they behave much more like a leased line. They cost more and need line-of-sight to the tower, but for a business that cannot tolerate downtime and has no fibre, this is usually the strongest option. Licensed operators hold ICASA ECS and ECNS licences to run their own network.
How a point-to-point wireless link reaches you
Satellite: for sites nothing else reaches
If you are genuinely off-grid, satellite is the connection of last resort, and it now comes in two flavours.
Geostationary (GEO) satellite has been available in South Africa for years. It reaches anywhere with a clear view of the sky, but the signal travels to an orbit roughly 36,000 km up and back, so latency is high (around 600 milliseconds), which makes real-time voice and video difficult. Low-earth-orbit (LEO) constellations sit far closer and cut latency dramatically, to the region of 40 milliseconds, making them far more usable for everyday business traffic.
Fibre alternatives compared
Match the technology to your location, your uptime needs and your budget.
| Option | Typical latency | Setup | Reliability | Best for |
|---|---|---|---|---|
| Business LTE | 30–70 ms | Days | Good (contended) | Quick interim link, most offices |
| 5G fixed wireless | 20–40 ms | Days | Very good in coverage | Fibre-like speed where 5G reaches |
| Licensed microwave | 5–20 ms | 1–3 weeks | Excellent, SLA-backed | Uptime-critical sites, no fibre |
| Satellite (LEO) | ~40 ms | Days | Good, weather-sensitive | Remote or off-grid locations |
| Satellite (GEO) | ~600 ms | Days | Reaches anywhere | Last resort, non-real-time use |
The right fibre alternative is not the fastest one on paper. It is the one that matches your location, your uptime needs and your budget, with a second link behind it for the days the first one fails.

Our verdict
Fibre is still the target, but its absence is not a dead end. For most offices, business LTE or 5G fixed wireless gets you online within days and is a fine interim or even permanent link. If downtime costs you money, a licensed microwave connection with an SLA is worth the premium. Satellite, and increasingly LEO satellite, covers the sites nothing else can. Whichever you choose, add automatic failover so a single outage never takes the business offline.
