by Andrew J. Shepherd Sprint 4G Rollout Updates Friday, August 19, 2016 - 2:04 AM MDT   Earlier this week, the two HTC 2016 Nexus handsets -- codenamed "Marlin" and "Sailfish" -- were caught in the net of the FCC OET (Office of Engineering and Technology) authorization database.   While Google has yet to reveal them officially as Nexus handsets, that HTC is the manufacturer of choice this year has been a heavily leaked secret the past few months.

[Teaser] Life's Good with VoLTE?

by Tim Yu Sprint 4G Rollout Updates Wednesday, March 16, 2016 - 9:13 PM MDT Authors Edit (8/25/16): According to a report, the LG G5 (and HTC 9) is indeed capable of 3xCA specifically for Sprint due to the intraband contiguous setup Sprint utilizes. The spotlight may have been largely on the Samsung Galaxy for the past few weeks, but from behind the red moon, a new contender has revealed itself. To keep it short, as per typical of a S4GRU teaser article, the model LS992 Sprint

Not just with AT&T, Sprint swaps spectrum with T-Mobile and VZW, too.

by Tim Yu Sprint 4G Rollout Updates Friday, March 4, 2016 - 8:25 AM MST   A little over two weeks ago, S4GRU published an article detailing a multi-market PCS 1900 MHz swap between Sprint and AT&T that increased spectrum contiguity for both operators in several markets. In that article, we mentioned how that spectrum swap might be the first of many, as there are numerous other markets in which Sprint and other licensees could mutually benefit by realigning disparate spec

[UPDATED] Teaser: Samsung Galaxy S7 and S7 Edge. One of "US." One variant each for all of the US?

by Josh McDaniel, Tim Yu, and Andrew J. Shepherd Sprint 4G Rollout Updates Wednesday, February 3, 2016 - 11:50 PM MST   Update: Further inspection of the FCC OET authorization filings has shown that while Samsung will produce only one "US" hardware variant each for the Galaxy S7 and Galaxy S7 Edge, it still will delineate operator specific "V," "A," "T," "P," and "R4" variants via firmware.   That firmware on the Sprint "P" variant, for example, will enable CCA/RRPP

Sprint enters the Relay race

by Tim Yu Sprint 4G Rollout Updates Monday, January 25, 2016 - 8:30 AM MST   For the past year, Sprint has commented a lot about its coming "Next Generation Network" deployment that aims to improve greatly Sprint's network capacity and coverage. Much of that speculation has been over how Sprint intends to feed backhaul to the "tens of thousands" of small cells it plans to deploy -- given Sprint's past history on getting backhaul delivered to its own macro cell sites as part o

Sprint's PCS spectrum position in Memphis goes from nothin' but a hound dog to Graceland

by Andrew J. Shepherd Sprint 4G Rollout Updates Thursday, September 3, 2015 - 3:28 AM MDT   Ladies and gentlemen, C Spire has left the building. In Memphis. Or so it seems.   Based on an FCC spectrum lease filing that came down the pike earlier this week, Cellular South dba C Spire has applied to lease all of its spectrum in Memphis to Sprint.
