Sprint showcases 1 Gbps over-the-air speeds in Silicon Valley

Sprint demonstrated live today 1 Gigabit per second (Gbps) over-the-air speed at its lab near Silicon Valley, Calif. This was the highlight of a day that showcased the innovation and what's possible on the Sprint network as the company unveiled technology with the potential to surpass wireless speeds of any U.S. network provider.

Named Sprint Spark, the super-high-speed capability demonstrates 50-60 Megabits per second (Mbps) peak speeds today with increasing speed potential over time. Given Sprint's spectrum and technology assets, it is technically feasible to deliver more than 2Gbps per sector of over-the-air speed.

"Sprint Spark is a combination of advanced capabilities, like 1x, 2x and 3x carrier aggregation for speed, 8T8R for coverage, MIMO for capacity, TDD for spectral efficiency, together with the most advanced devices offering both tri-band capability and high-definition voice for the best possible customer experience," said Dan Hesse, CEO of Sprint.

Sprint plans to deploy Sprint Spark in about 100 of America's largest cities during the next three years, with initial availability in five markets today. Sprint 4G LTE service will be available by mid-2014 to approximately 250 million Americans, and Sprint expects 100 million Americans will have Sprint Spark or 2.5GHz coverage by the end of 2014. The first markets with limited availability are New YorkLos AngelesChicagoTampa and Miami. The first smartphones with Sprint Spark capability are scheduled for customer availability in early November.

How Sprint Spark works
Sprint Spark combines 4G FDD1-LTE at 800 Megahertz (MHz) and 1.9 Gigahertz (GHz) and TDD1-LTE at 2.5GHz spectrum, TDD-LTE technology (2.5GHz), and carrier aggregation in the 2.5GHz band. These spectrum assets, technology and architecture are designed to deliver a seamless customer experience via tri-band wireless devices. Tri-band devices, named for their ability to accommodate multiple spectrum bands, support active hand-off mode between 800MHz, 1.9GHz and 2.5GHz, providing data session continuity as the device moves between spectrum bands. 

In addition to demonstrating the 1Gbps speeds via over-the-air wireless, Sprint has also commercially deployed one of the longest 100Gbps circuits in the United States. That live transmission required no signal regeneration over a distance of 2,100 km, or 1,304 miles.
