T-Mobile upgrades 4G network for speedier downloads

T-Mobile

T-Mobile is announcing an impressive-sounding upgrade to its 4G network and T-Mobile customers in Las Vegas, New York, and Orlando will be the first to benefit from it.

Apparently the carrier will be doubling the speed of its 4G network and offering theoretical download speeds of 42 Mbps (megabits per second) — oh yes, that's pretty darn fast. How fast? An average song is about 5 megabytes, and an average movie about 750 megabytes, so at 42 Mbps, that'd be 7 seconds to download Lady Gaga's latest hit or 16 minutes to grab a quality version of "You've Got Mail."

After the cities mentioned above, the upgrade will be made in Chicago, Long Island and Northern New Jersey.

By mid-2011, T-Mobile hopes to bring the faster speeds to 140 million American customers. The announcement was tied to the spring CTIA Wireless trade industry show this week in Orlando, Fla.

While making these upgrades to its network, T-Mobile will also be offering a new 4G Mobile Hotspot — which will allow customers to connect up to five Wi-Fi-enabled devices to the 4G network — as well as a series of new 4G laptop sticks including the T-Mobile Rocket 3.0 which will be the first laptop stick capable of taking advantage of the new 42 Mbps speeds.
