AppleInsider has an interesting article about how it's planning on rolling out 4G to 80% of Americans, while if they make it cover 97%, it would cost an additional $3.8 Billion. Interesting quote: I wonder what the discrepancy between the % of population and % of land mass is. So 80% of the US population lives on just 20% of the US land mass? Does that include just people's home, or does that include where people work as well? I can understand some places like northern Alaska or the Rocky Mountains because I don't see many people spending that much time there. But according to the map in the article a lot of people will be missed out due to living in rural areas. What, do farmers not need 4G while everyone else does? Anyone know how much profit AT&T gets a year? Seems like a company as big as AT&T could probably afford to do the expansion. Plus, think how much more money it could make if it provided access to the rural population. 13% of 300,000,000 people is over 30,000,000, which is quite a bit. Also, I've heard reports (sorry, I forget where) that one reason why China and the other BRIC countries are doing so well is because they're actually investing in their infrastructure.My feeling is that AT&T may not see the investment directly paying off, but the extra services will help the people they provide be more productive, make more money & maybe pay for more of AT&T's products & services.
