LTE vs Fibre for Your Business: Which One Actually Works?

The question people usually ask is "which one is better," fibre or LTE. The more useful question is which one is better for your specific situation, since the honest answer depends entirely on location, budget, and what the business actually needs day to day.

Fibre is a physical cable running into the building, carrying data as light through glass or plastic fibres. Speeds are symmetrical, uploads keep pace with downloads, and neither weather nor distance touches the signal, which makes it genuinely stable. The trade-off is installation: it may not be available at your address at all, and where it is, four to eight weeks between order and activation is normal. If the physical line gets cut, service stops until someone repairs it.

LTE, or 5G fixed wireless, runs over the mobile network through an external antenna connecting to the nearest tower. No digging, no cabling, and setup can happen the same day if the hardware's in stock. The trade-off runs the other way: advertised speeds are "up to" figures that shift with distance to tower and network congestion, and heavy rain can affect signal. If one tower has a bad day, the connection can often shift to another automatically, which is its own kind of resilience fibre doesn't have.

On price, fibre in South Africa currently runs R500 to R1,200 a month depending on speed tier, sometimes with a once-off installation fee. LTE/5G fixed wireless runs R429 to R699 a month with no installation fee, the device cost usually folded into the contract. Fibre availability has expanded significantly in urban and semi-urban areas and is worth checking address by address; LTE's advantage is showing up wherever there's signal at all, including rural areas fibre hasn't reached yet.

Fibre tends to be the right call if you're in a covered area, need consistent speed for video calls or heavy cloud work, upload large files regularly, and can tolerate the installation wait. LTE tends to be the right call if fibre isn't available yet, you need connectivity live within days rather than weeks, your team is mobile, or load shedding has you wanting genuine network-level redundancy rather than just backup power.

For most South African SMEs, the honest answer is having both: fibre as the stable primary connection, LTE as the automatic failover if that primary line goes down. A secondary router running R400 to R700 a month sounds like an unnecessary cost right up until you calculate what eight hours of downtime actually costs the business, at which point months of backup fees look cheap by comparison.

Working out which setup fits starts with checking real availability at your exact address, being honest about actual peak data usage rather than average usage, and pricing in what downtime would genuinely cost if it happened tomorrow. Response times and restoration guarantees in the provider's SLA matter more in practice than which technology sits underneath them.
