There is only one reason. It's much more efficient. Engineers have to keep slicing things thinner and thinner to accommodate more and more people and needs. This impacts everything. Food, water, shelter, medications, transportation, communications, etc. Efficiency is king. It has to be.
- mrswag 10y agoFM works, and doesn't need any addition when you increase the number of listeners. I don't get it. Why throw away millions of perfectly fine radios?
- w8rbt 10y agoDigital is more narrow and compact and allows more efficient use of the spectrum in general. More transmissions, different uses, sharing, freeing space up for other allocations, etc. All of that is resource/demand driven. More people is more demand.
- gpvos 10y agoWhile DAB transmission is more efficient than FM, the receivers are more complex and draw more power than FM receivers. I'm not sure the tradeoff is right in this case.
- askvictor 10y agoI get that argument for tv transmission, but the FM bandwidth is tiny by comparison, so just doesn't seem to justify the switching pain (particularly regarding cars)
