Today at CTIA, T-Mobile announced expansion of its faster HSPA+ network and a boatload of new devices to take advantage of it.

T-Mobile says it is doubling the speed of its HSPA+ network to achieve a theoretical download speed of 42 Mbps. Customers in Las Vegas, New York and Orlando will be the first to get it, followed closely by Chicago and further expansion of the New York network into Long Island, N.Y., and Northern New Jersey.

By mid-year, T-Mobile expects 140 million Americans in 25 cities to have access to increased 4G speeds. The current 21 Mbps HSPA+ network covers 200 million POPs, 140 million of which will see 42 Mbps service before 2012.

HSPA+ (also called Evolved HSPA), provides faster speeds through multiple-antennas (MIMO), higher order modulation (64QAM) and channel bonding (with multiple carriers). While 64 QAM (Quadrature Amplitude Modulation) only works if you’re close to the transmitter, HSPA+, can deliver theoretical peak throughput rates on the downlink up to 42 Mbps.

It will mostly benefit HSPA hotspots serving local areas, such as airports, campuses and shopping malls. However, in a fully loaded network with interference from adjacent cells, overall capacity gains will be more modest range of 20 to 33 percent.

Qualcomm’s new HSPA+ chipsets like the MDM8225 will support both HSPA+ MIMO antenna technology as well as HSDPA carrier aggregation. That allows aggregation of carriers from different frequency bands to deliver doubled data rates.

T-Mobile will introduce seven new HSPA+ devices this spring spanning smartphones, tablets and mobile broadband products, including:

  • T-Mobile G2x with Google: The latest 4G smartphone to join T-Mobile’s innovative G-series devices, the G2x is powered by a 1GHz NVIDIA Tegra 2 dual-core processor, brilliant 4-inch capacitive touch screen display and preloaded video games, such as Need For Speed SHIFT HD.
  • T-Mobile Sidekick 4G: The recently announced Sidekick 4G will cost $99.99 with a qualifying plan including unlimited data on a two-year service agreement after $50 mail-in-rebate card, or $149.99 with a qualifying plan including data on a two-year agreement.
  • T-Mobile G-Slate by LG: Powered by Android 3.0 (Honeycomb), the G-Slate features an 8.9-inch, 3D-capable, multitouch HD display and the ability to record 3D and full HD video. It uses a 1GHz Tegra 2, with 32GB internal memory and front and rear (5MP) cameras. Users can access their TV shows, magazines and games with pre-installed applications such as T-Mobile TV, Need for Speed and Zinio eReader. The T-Mobile G-Slate will cost $529.99 after $100 mail-in-rebate card with a qualifying mobile broadband plan on two-year agreement, voice line and enrollment in EasyPay.
  • Laptop Sticks: The T-Mobile Rocket 3.0 is the first 42 Mbps-capable 4G product able to take full advantage of T-Mobile’s new 42 Mbps service available in select markets. T-Mobile also plans to deliver two additional 4G laptop sticks capable of delivering peak download speed of 21 Mbps, including the T-Mobile Jet 2.0 and the prepaid T-Mobile Rocket 4G. The T-Mobile Jet 2.0 will be available March 23 at no cost after $50 mail-in-rebate card with a qualifying mobile broadband plan on two-year agreement, voice line and enrollment in EasyPay.
  • T-Mobile 4G Mobile Hotspot: The ZTE mobile hotspot is a compact 21 Mbps-capable device that enables customers to extend the power of T-Mobile’s LTE Network to any Wi-Fi-capable device.

In other T-Mobile news, T-Mobile and Nokia unveiled the Nokia Astound, an affordable, feature-rich smartphone that will be available exclusively from T-Mobile starting April 6 for $79.99 after a $50 mail-in-rebate card with a two-year service agreement and qualifying voice and data plan.
