We all know that a 3 dB improvement can be a big number in engineering terms but what does it mean in terms of business metrics? More specifically, what does it mean for mobile TV?
Quite bit as it turns out.
A receiver that is 3 dB better than a "typical" receiver can achieve (at least) a given quality level in a coverage area around 50% greater than the reference.
A simulation conducted in Europe recently using a single transmitter over Berlin (EIRP 100 kW) resulted in a 56% larger viewing audience for the same output power: 940,000 people instead of only 600,000 people covered on a basic receiver.
Another metric from the study: Instead of investing 300 million Euros to create a mobile TV infrastructure, Europe would only need to invest 200 million Euros.
That's a tidy sum and it's all due to one engineering team being 3 dB better than all the rest.
