[citation][nom]Pei-chen[/nom]Calling to Japan is more expensive than Iraq? I guess our rebuilding of Iraqi infrastructure is really going somewhere. I wouldn’t be surprise if Iraq has the highest bandwidth internet.[/citation]
Not including hardware costs, the service contract with Bentley-Walker for a 2 Mbps/512 Kbps connection (shared) runs about $3985 per quarter (that's $1330/mo, something to think about next time you complain about your ADSL bill). Of course, I don't pay all that out of pocket; acting as a mini-ISP, I share the uplink with other people who chip in at $80/mo each. With 16 people buying we just about break even on the monthly cost. $80 may seem steep given the quality of the connection, but it's not a bad deal for Iraq. Remember also that the costs mentioned are for an admittedly high-tier plan; lower bandwidth allocations are available for proportionately less cost.

I would seriously doubt they have the highest bandwidth, or even close. The main form of high-speed internet connection in Iraq is Satellite. My few friends whom are in the service (which is not many) have all complained about how slow the speeds are there. Some who play WoW, tried a few times to log in and just do some quests and found the lag unbearable.
I doubt because it's cheaper to call Iraq, that they have a faster or better telecommunications infrastructure than Japan.
I'd say it's more likely because we have a lot of soldiers there, the rates might be a tad lower so families and soldiers can keep in touch easier and cheaper.
