I'm trying to settle an arguement with my brother over how much per hour COD: Black Ops uses on PSN when/when not hosting and with no voice chat.
Help me out?
It's almost a universal that online shooters have a bandwidth level of about 10kbits/s up and 60kbits/s down, for the average client. For the host, that changes to 60 kbits/s up and 10kbits/s down per player, which is why you can't host more than 12 players if your line isn't faster than 896kbits/s upload (which settles to a cruise level of about 700 kbits/s)
So, if you're the client, you'd be drawing around 60 kbits/s, which is
60*3600 kbits/hr, so in 2 hours you'd use
120*3600kbits, which is 432,000 kbits or about 432 Megabits, or 420 megabits, depending on whether a megabit is 1 million bits or 2^20 bits.
Note that's not MB, which is read "megabyte," in which there's 8 megabits, if you use the same "mega" convention; because 8 bits = 1 byte. 432 Megabits would equal about 54 megabytes (MB). But I doubt your line has a maximum download listed in Megabytes, because providers measure speed in bits not bytes.
If your line had, say, a 20 Gigabit download limit, you could be a COD client for maybe 90 hours before hitting it. Then there's the possibility that COD might range as high as 100kbits/s or as low as 50kbits/s for client. Then you have usage ranging from
300Mbits to 500Mbits download
50 to 80 Mbits upload
as client for 2 hours;
500 to 800 Mbits download;
3,000 to 5,000 Mbits upload;
if you host a 10-player room for 2 hours. Yow!
bandwidth monitors. Use a search engine to download a free one, and you can pinpoint the exact level of dl and ul yourself on your pc. Make sure COD is the only thing using bandwidth and you'll get reliable numbers
