Fiber vs Wireless: Where the ROI Actually Is

The ROI comparison is not monthly fee against monthly fee — it is the fee plus the civil works, divided by the months you will actually use it. Fibre with a large one-off build cost can lose to wireless over a two-year horizon and win over five.

Include the cost of waiting. A site that cannot open for six weeks because the fibre is not in yet has a number attached to it, and it usually dominates the comparison.

Comparing fiber and wireless on monthly cost alone produces the wrong answer often enough that it is worth doing the arithmetic properly. The recurring fee is rarely where the difference lives.

The costs that do not appear in the monthly figure

Doing the comparison over the contract, not the month

Take the full term. Add installation, civil works, equipment and the value of the months the site would otherwise not be operating. Then divide. A wireless link that costs more per month frequently costs less over thirty-six months, because it started three months earlier and required no construction.

The reverse is also true and worth stating: at high and growing capacity, fiber wins clearly, and the more traffic you expect to add, the earlier it wins.

The hybrid case

Fiber as primary with wireless as the diverse backup usually looks like the expensive option on a spreadsheet, because you are paying for two circuits. It is the only design that survives the most common Brazilian failure, which is a cut duct. Priced against a single day of downtime at a site that transacts, it stops looking expensive very quickly.
