TODAY VISION • Multiple devices for different services

• Move in and out of coverage zones

• Risk losing signal strength at edges of tower

coverage / in buildings

• Existing devices perform better; a selection of

new, universal devices automatically access all

networks / services via strongest signal

• Consistent coverage / quality across all towers /

spectrums, even in buildings

• Seamless, superior service indoors, across the

city and around the country

Positive impact

Enhanced customer experience Sprint Network Vision is expected to profoundly enhance the customer experience
