What is your usage?The answer to "how much internet speed do I need" comes down to your type of activities, usage frequency and length, number of devices and the number of people connected to the same bandwidth. The latter includes both the number of employees or the number of people using the internet at your residence. On top of that, the number of customers using the same bandwidth network will factor in depending on the type of broadband service you will sign up for.So those factors are all linearly proportional meaning as one augments, the speed needs also increase. The more users, devices and people connected at the same time the higher the bandwidth needs to keep everyone happy.Since the recent tendency is online streaming, and that is what usually consumes the most bandwidth, let's look at Netflix. Netflix recommends a 3 Mbps connection for one standard-quality stream and 5 Mbps for a high-definition stream. Two simultaneous HD quality streams would need around 10 Mbps.Online gaming doesn't require much bandwidth to play online, but if you are looking to download a game, then the size of the files would require lots of it.
