It’s a cold Saturday afternoon, and I am standing and staring into a gated area near a cell phone tower. My date for this outing is frantically taking pictures and discussing the exciting upgrades to the equipment which have occurred since our last visit. I have no idea what he is talking about, all the mechanical stuff looks exactly like it did a few weeks ago. To me, it happens to look exactly like the 3 other sites we visited today.

  2. by Robert Herron Sprint 4G Rollout Updates Monday, November 11, 2013 - 11:55 PM MST S4GRU Staff and Members have been anxiously waiting for over a year for smartphones that would support all three of Sprint’s LTE bands. Since April 2012, Sprint LTE devices have been limited to only one band. Band 25 (1900MHz in the PCS Band). Subsequently, Sprint closed down the Nextel network and picked up another LTE band (Band 26). Also, Sprint purchased Clearwire and picked up another LTE band that they had started to use (Band 41). So Sprint now has use of three LTE bands which will allow it to provi

This weekend was a moment of great joy for many of us Sprint Network Enthusiasts as 4G LTE started going live at hundreds of sites across the country in a few select markets. However, our geek party was frequently interrupted by incessant whining. One of the chief frequent whines I heard around S4GRU was related to

The first major addition of compatible sites to its network in a decade. Past expansion has been limited to buyouts of Nextel and Clearwire, both of which included networks of different technologies. Organic growth has not been on the table for Sprint in some time. Sprint is expected to announce these plans in the not too distant future, once finalization of details and funding is complete.

In simple terms, it tells the device how to scan for various wireless cell systems, which ones are native, and which priority to use them in. If there isn't a native Sprint signal available, the PRL defines which roaming partners to scan for, which ones should be used, and in what order of preference to scan for them in. Contrary to belief and what some Sprint reps may tell say, a PRL is not a list of cell sites. You do not need a new PRL update to receive servi

Removable SIM cards have long been part of the Network Vision roadmap for 2013, so it looks like that time may have arrived. S4GRU welcomes you to the first major Sprint handset announcement of 2013.

One day, you won’t have to worry about holding the phones as Sprint moves to VoLTE for its voice telephone services. That is because VoLTE (Voice over LTE) will allow customers to do a voice call and LTE data simultaneously.

He was able to confirm some of their plans for the transition to VoLTE for voice. In recent months, Sprint has been qu

Its authorizations were uploaded, then quickly rescinded, citing confidentiality reasons. Well, today, the LG D820 authorization documents are back.

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 of Network Vision.
