Nobody's pretending "42Mbit/s" means "42Mbit/s" in real life -- but this video shows the actual speeds you'll be seeing... and they're quite amazing.
In this video, Telstra wireless engineer, Jared King, speed tests the telco’s Ultimate USB modem around Melbourne. The modem isn’t on sale yet, but when it is released it should provide a significant speed boost through its use of dual-carrier technology.
The device will allow Telstra customers to send and receive wireless data using two channels simultaneously, with the telco claiming it allows peak network downlink speeds of 42Mbps, although actual customer speeds will be lower.
