The math that debunks the myth of online radio data usage

Listening to online radio costs 28 MB per hour, according to a calculation making the rounds in the debate

How much does it really cost to listen to the radio over the internet? The answer that, according to one participant, debunks the viral video lies in primary school division: most stations broadcast at 64 Kbps, which is 8 KBytes per second. Multiplied by 3,600 seconds, a full hour of online radio comes to 28.125 MB. Less than the size of a group photo on WhatsApp. The "trick" to saving data, then, was no trick at all: it was simply never doing the math.

The calculation, laid out with a schoolteacher's patience, exposes those who present basic arithmetic as a discovery. With monthly plans of 1 or 2 GB, streaming the radio for more than an hour would amount to negligible usage, always according to that estimate. The real issue is that the phone may not have FM, and that is where the actual problem begins.

The good old radio set wins by a landslide again

The most repeated solution is the oldest one: listening to the radio on the radio. A transistor set at home, a mini hi-fi at work, the station preset on the phone, and the car's RDS when you drive out of town. The classic options, this camp argues, remain the simplest and most effective. They use no data because they don't need any.

The problem comes with the hardware. Phones have had FM radio since 2002, and for years it was a standard nobody questioned. Today the antiestéticature is disappearing from some expensive models: iPhones have never had it, and some top-end Android phones have been dropping it. Some see it as a regression that is hard to justify when the same device handles everything else.

FM has its cracks too

It is not all nostalgia for the analog dial. In big cities the spectrum is saturated and trinc a station on the move becomes an odyssey. Add to that the aggressive compression of music audio, which punishes listeners with a trained ear. Streaming, on the other hand, lets you tune into local and foreign stations that would never reach an antenna.

Podcasts emerge as a third way: download over wifi and listen later, without depending on coverage. The objection is fair: not all stations publish their shows, and some take days to upload them. For live broadcasts, the match, or breaking news, no download will do.

In the end, online radio ruins nobody: 28 megabytes an hour is pocket change in digital terms. The expensive part is the phone that forces you to use it because they removed the antenna.
