While claiming a record-setting theoretical maximum speed of 21Mbps, the Telstra Turbo 21 mobile broadband modem will most likely deliver download speeds ranging from 550Kbps to 8Mbps in practice. Upside If you download a lot of songs, video or other data, the idea of mobile broadband speeds nearly four times the status quo is indeed enticing. While an average real-world connection of 550Kbps to 8Mbps is a fair way from the theoretical maximum of 21Mbps, Telstra was able to demonstrate network speeds of 17Mbps at the Turbo 21 media launch.
