Through spectrum efficiencies associated with Network Vision, Sprint intends to repurpose some of its 800MHz spectrum for CDMA service, thereby enhancing coverage, particularly the in-building experience for customers. Augmenting its 1.9GHz footprint with 800MHz, Sprint expects its CDMA coverage density will increase throughout the country. More density generally equates to fewer dropped calls and a more seamless network experience for customers. According to a 2010 PCWorld 13-city, 3G drive test, Sprint had the most reliable network. The Network Vision plan expects to enhance that competitive position.
“This is a very bold move,” said Berge Ayvazian, senior consultant, Heavy Reading. “Sprint was first with an all-digital wireless network; the first to upgrade to EVDO; and, more recently, the first to broadly offer 4G services. Sprint is once again first to deploy a common converged mobile network that will strengthen its 3G services; enhance its 4G technology options; and continue delivering the industry’s leading push-to-talk offering.”
