Network Vision is Sprint’s plan to consolidate multiple network technologies into one new, seamless network with the goal of increasing efficiency and enhancing network coverage, call quality and data speeds for customers across the United States.
Sprint has an all-new network, providing customers across the country with significantly better call quality and faster data speeds in more places.
Sprint now provides 4G LTE service in 471 cities nationwide. Sprint 4G LTE offers peak wireless speeds of 25Mbps and is designed to greatly improve the performance of video and audio applications

By mid-year 2014 Sprint is expected to substantially complete the rip and replacement of its network equipment. As a result, voice quality is enhanced and Sprint customers in upgraded areas are seeing better performance on their smartphones, mobile broadband connection cards and mobile hotspots when using the Sprint 4G LTE and 3G networks. Customers can expect to experience the following performance improvements:
Faster data speeds that enable instant Web access for news updates, HD viewing and game-playing, quicker video downloads and clear video chats.
Better signal strength when making a call or using the Web.
Fewer dropped calls for peace of mind when talking to friends, family or colleagues.
Improved voice quality with HD Voice, a new Sprint standard for crystal-clear voice calls.
Sprint Spark, an enhanced 4G LTE service available in 24 cities, is built for data and designed to deliver peak wireless speeds of 60Mbps today on capable devices. With its unique combination of network technologies, spectrum capacity and tri-band devices, Sprint Spark is designed to greatly improve the performance of video and other bandwidth-intensive applications. It enables stutter-free video chat on-the-go and mobile gaming that leaves lag behind.
America’s newest network also includes HD Voice in many cities today, with nationwide availability expected by mid-year. HD Voice is a new Sprint standard for crystal-clear voice calls. It provides a fuller, more natural-sounding voice, plus noise-cancelling technology that virtually eliminates background noise from places like a busy road or crowded restaurant. 
John Saw, Chief Network Officer, Sprint
“We’re making great progress building America’s newest network and customers are pleased with the faster data speeds and crystal clear voice calls,” said John Saw, chief network officer at Sprint. “Today our network is delivering significantly better service. Furthermore, it’s a strong foundation for tomorrow – a time will ultimately come when customer demands for bandwidth, and technology changes with 4G and beyond, will require the kind of platform we now have in place.”
New cell sites
Through a complete rip and replacement of its network, Sprint has installed new network equipment and software that brings together multiple spectrum bands, or airwaves, on a single, multimode base station. The new equipment makes it easy to accommodate Sprint’s three spectrum bands – 800 MHz, 1.9 GHz and 2.5 GHz.
Sprint Direct Connect
Another part of Sprint’s all-new network is improvements to the Sprint Direct Connect push-to-talk service. Customers who migrate to Sprint Direct Connect experience three times the push-to-talk coverage compared to iDEN, international direct connect reach to Latin American countries, and 3G broadband data capabilities.
In addition, Sprint is focused on wireless recycling and renewable energy in its networks, ensuring it does its part to incorporate corporate responsibility into every major touch point of its business. Sprint uses the phrase "corporate responsibility" to describe its approach to balancing its business objectives with its environmental, social and economic responsibilities. Sprint has been recognized for the following sustainability efforts:
Sprint ranked No. 3 on Newsweek's 2011 Rankings of America's Greenest Companies, up from No. 6 in 2010 and No. 15 in 2009, based upon environmental impact, green policies and performance, and reputation survey scores as of October 24, 2011.
Sprint has upgraded its network to use single, multi-mode base stations.
Sprint cell sites aremore compact, more energy efficient, and able to provide better coverage and call quality tocustomers.
This will reduce Sprint's total energy demand and the company's carbon footprint. Sprint is the only U.S. telecommunications company to commit to reducing its GHG emissions by an absolute 20 percent by 2017.
Previous 3G and 4G Base Stations
New Multi-Mode Base Station
With a rip and replacement of its network equipment, Sprint has made substantial changes to the cell sites that power its wireless network. The top image shows Sprint’s formerbase stations, which required single, refrigerator-sized cabinets for each technology. Large black coaxial cables ranfrom each cabinet to the top of the cell tower, which has an inherent loss of signal. The new multi-mode base stations require less space. Other advantages include the ability for Sprint to use spectrum bands on multiple technologies, replacing coaxial cables with fiber that is not affected by signal loss and improved remote radio heads that replace less efficient radios.
The implementation of multi-mode technology throughout the Sprint network:
· Enhances service
· Creates network flexibility
· Reduces operating costs
· Improves environmental sustainability
