Sprint Demos 1Gbs Mobile Data Download -- Launches Early Variant Today
USA based Sprint has demonstrated a mobile data download link that delivered 1Gbps download speeds under laboratory conditions.
Named Sprint Spark, the capability demonstrates 50-60Mbps peak speeds today with increasing speed potential over time. Given Sprint's spectrum and technology assets, the company thinks is technically feasible to deliver more than 2Gbps per sector of over-the-air speed.
The company is launching the service today -- although compatible smartphones will take a few weeks to arrive.
The first markets with limited availability are New York, Los Angeles, Chicago, Tampa and Miami. The first smartphones with Sprint Spark capability are scheduled for customer availability in early November.
"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. The first smartphones with Sprint Spark capability are scheduled for customer availability in early November.
Sprint's 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.
How Sprint Spark works
Sprint Spark combines 4G FDD1-LTE at 800MHz and 1.9GHz and TDD1-LTE at 2.5GHz spectrum, TDD-LTE technology (2.5GHz), and carrier aggregation in the 2.5GHz band.
Sprint Spark components
Sprint is building the Sprint Spark capability using a unique combination of spectrum capacity and network technologies. Today the company has approximately 55,000 macro cell sites; a level Sprint expects staying at for the next few years. The company also anticipates using small cells to augment capacity, coverage and speed. Small cell deployment is expected to begin in 2014, continuing into 2015 and beyond.
A key ingredient enabling Sprint Spark is equipment compatibility with the architecture of the Sprint initiative known as Network Vision. Alcatel-Lucent, Nokia Solutions and Networks and Samsung have been selected to provide 2.5GHz radio heads and to enable Sprint Spark. Each company will service approximately one-third of Sprint's deployment markets. These 2.5GHz radios are expected to have capabilities for 8 Transmitters 8 Receivers (8T8R), which will be a first deployment of its kind in North America. These radios will be capable of improved coverage, capacity and speeds when compared to the more traditional 2T2R or 4T4R radios used by our competitors.
Sprint Spark comes to life for customers via their devices. Building on Network Vision's multimode capability, Sprint Spark is designed to accommodate all of Sprint's spectrum bands on a single device. These tri-band smartphones are designed to give users the best experience by transparently shifting from one band to another, depending on such factors as location or type of application.
The first tri-band devices will be available to customers in the next few weeks and offered by HTC, LG and Samsung.
The company hasn't outlined pricing details yet.
