Fibre vs 5G: The Ultimate Comparison
The battle for the home. We look at the pros and cons of the two fastest technologies in SA.
Fibre vs 5G: Which is the Best Choice for You?
Executive Summary
In 2025, the line between fixed and wireless internet has blurred. 5G "Home Internet" now offers speeds that rival fibre, often with no installation fees and instant setup. However, fibre remains the bedrock of the digital economy due to its unmatched stability and symmetrical performance. This guide provides a head-to-head comparison to help you decide which technology deserves to be the heart of your home.
Head-to-Head Comparison
1. Speed
- Fibre: Offers guaranteed tiers (e.g., 100Mbps means 100Mbps).
- 5G: Offers "Up to" speeds. You might get 500Mbps at 3 AM but only 20Mbps at 8 PM when the tower is busy.
2. Stability
- Fibre: Immune to weather and radio interference.
- 5G: Can be affected by heavy rain, wind, and even the number of people in your neighborhood using their phones.
3. Latency (Ping)
- Fibre: 2ms - 10ms. The gold standard for gaming.
- 5G: 15ms - 40ms. Good, but prone to "jitter" spikes.
4. Installation
- Fibre: Requires drilling, cables, and a technician visit (3-10 days).
- 5G: "Plug and Play." Buy the router, insert the SIM, and you're online in 5 minutes.
Comparison Table: Fibre vs. 5G
| Feature | Fibre | 5G Home Internet |
|---|---|---|
| Setup Time | 3 - 10 Days | Instant |
| Symmetry | Yes (often) | No (Upload is much slower) |
| Reliability | Very High | Medium |
| Price per Mbps | Low | Medium |
| Contract Length | 12 Months / M2M | Usually Month-to-Month |
When to Choose Fibre
- You are a gamer or remote worker.
- You have a large family with many devices.
- You want the most stable connection possible.
- You plan to live in your home for more than a year.
When to Choose 5G
- You are a renter who moves frequently.
- You need internet today.
- You live in an area where fibre hasn't been installed yet.
- You are a light user who values simplicity over raw performance.
Practical Checklist: Making the Call
- Check 5G Signal: Use your phone to see how many "bars" of 5G you get inside your house.
- Check Fibre Availability: If fibre is available, it's almost always the better long-term choice.
- Compare the FUP: 5G plans often have much stricter "Fair Use" limits than fibre.
- Consider Loadshedding: 5G towers often fail during extended power outages, whereas fibre exchanges usually have better backups.

Frequently Asked Questions
Is 5G cheaper than fibre?
Sometimes. Entry-level 5G plans can be cheaper than fibre, but once you look at high-usage or high-speed tiers, fibre offers much better value for money.
Can I use a 5G router for gaming?
Yes, but expect occasional lag spikes. For casual gaming, it's fine. For competitive play, fibre is significantly better.
Does 5G work during loadshedding?
It depends on the tower. Many 5G towers in SA have batteries that only last 2-4 hours. Fibre hubs generally have much longer-lasting backup systems.
