Sprint has made plenty of changes since their new CEO Marcelo Claure took over at the helm of the company, and it looks like expanding out their 4G LTE networks on a large scale is finally going to become part of those changes. According to news coming out from S4GRU(a site that focuses on Sprint 4G LTE news only)Sprint is in the planning stages of expanding out the 4G network and adding a total number of 9,000 new sites across the U.S. At the moment this information comes from an anonymous source of S4GRU's from inside Sprint, so with that being said this is still just a rumor and they haven't officially opened up about these plans to expand on 4G LTE just yet, although those details are expected to come out not too far from now.
Since Sprint hasn't officially announced their plans for an expansion of LTE sites, there are no details explaining where the new site expansions will be exactly, although S4GRU does have a map which shows off what they believe to be the general area or region where the new 4G LTE sites will be located which we have posted below. They also give a comprehensive breakdown of sorts on how Sprint is planning to attack the expansion, which includes building up new site locations and decommissioning and converting old iDEN sites.
In total Sprint is said to be looking at spreading out the expansion over a series of various types, including 5,000 new Sprint Spark only sites utilizing the TDD-LTE 2600 frequency. They're also said to be planning the decommission and conversion of 1,100 iDEN sites and turning them into new CDMA/LTE coverage. A series of 1,600 new LTE expansion sites are going to be targeting areas where there are high numbers of roaming traffic from customers, and lastly Sprint is also said to be adding 800 new Dual band sites aimed at targeting areas where they are expecting new market growth to occur, and 500 new tri-band sites to help cover the areas where the 1900 and 2600 bands won't reach customers. Although there is no definitive time window for these roll outs, if they are in fact happening the way their laid out Sprint subscribers could be in for some much needed improvements to the network, albeit with a significant amount of time to complete the initiatives.
