Internet radio transmissions are typically downloaded in Kilobytes per second (Kbps) and the standard speed of an internet radio transmission comes in at around 128 to 320 Kilobytes per second. If you download an internet radio transmission that comes in at 128 Kilobytes per second for 60 minutes then you will have used 57.6 Megabytes of data in that 1 hour. If you stream an hours worth of internet per day for 30 days then you would have eaten up 1.7 Gigabytes of data, and of course, the higher the quality of the broadcast, the more data you will be using up.
