Bandwidth is the most important aspect of internet service. How much bandwidth you have will determine how much you can do. In some places the basic internet package is just 4Mbps. So what can you do with 4Mbps? Simple, not much, at least nowadays. Remember a full HD 1080p stream can and will pull 8 to 10 Mbps, to get the best quality picture in HD. 4k content at 4Mbps, don’t even think about it. 4k can consume up to 25Mbps or more. Remember this would be just one 4k TV in your house, two TV’s would consume up to 50Mbps at any given time.
