Most people have broadband at home to play things like online gaming, and other use for this kind of speed. Some have with the phone service and USB devices that you all have a faster connection to the street. Is it good enough to actually use for online games?
The first question you are facing is the actual bandwidth. Many of these types of connections are limited to around 5 gigabytes of transfer per month total. This means that you have a cap on your connection, you will either you or cost you a lot more money come in additional charges if you make this mistake.
Many online games like the popular World of Warcraft can take up to 50 megabytes of transfer per hour. On a compound 5 gigabytes, which means you can get about 100 hours of play time on this type of device. When you play a game online, with a management tool to see how much bandwidth you are uploading and downloading. Add these two numbers to get an idea of how much you want to really use.
There is another factor to be considered. If you play a game online, there is a latency. It is the measure of time between your keystrokes and actions contained on the server. For example, if you are right it is a time difference when you press the button and when the character actually jumps in the game.
At ports such as USB, in general, the latency is not very good. You can read more for a period of one second, you get a big disadvantage, add in online games where timing is very important. You will not be able to play very competitively on some links that leave to signals from mobile phones. While it can work for you, it might really lag too much fun.
