Sprint recently indicated that its years-long Network Vision project is coming to a close. Sprint's 1900MHz LTE network covers 260 million POPs, according to Sprint CFO Joe Euteneuer, who made the comments at a Bank of America investor conference this week. Sprint's 2.5GHz LTE network covers 92 million POPs and its 800MHz LTE network will cover 100 million POPs by the end if the year. "I think from a network standpoint we have been waiting to get to this point of having a network that is substantially complete," said Euteneuer. Sprint said it will continue to add coverage in the 1900MHz band as its obtains more spectrum. All Sprint smartphones support tri-band LTE, which Sprint markets as Sprint Spark. Spark-compatible handsets are able to use whichever of the three spectrum bands (800MHz, 1900MHz, 2.5GHz) offers the strongest coverage in areas where all three bands are available. Sprint had previously said Sprint Spark would be available to 100 million people by the close of 2014, and it now appears that goal depends on deploying LTE to its 800MHz spectrum. All the major carriers are supplementing their LTE networks with additional capacity in other spectrum bands. For example, Verizon operates LTE in the 700MHz and AWS bands. AT&T and Verizon cover about 300 million POPs each with LTE. T-Mobile covers about 250 million. Sprint's Euteneuer also noted that Sprint will push an over-the-air update to the Apple iPhone 6 and 6 Plus in the next two to three months to enable Wi-Fi calling.
