- 12.2 kilobits/second = high-quality audio codec used by cellphones
- 58 minutes = average time American spends on phone per day (proxy for Bahamians)
- 371,960 = population of The Bahamas
Multiply these numbers together and you get the surprising number of:
That's the size of a $90 hard drive worth of data every day, or $33,000 per year worth of storage.
Or, in terms of bandwidth, it's 160-mbps -- a lot slower than the gigabit Ethernet connection on your laptop.
The upshot is this: technologically, the ability to intercept an entire nation is trivial.
Wait, that's an upshot? ;)
Only 26% of that 58 minutes is voice, so isn't it 478GB/Day?
G.729 compressed is 8 Kbps. G.711 is 64 Kbps. It's unlikely you're going to compress further than 8 Kbps even with silent time.
