Sprint 4G Rollout Updates

Sprint is embarking on a significant expansion of its network. 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.
Since the beginning of the year, Sprint CEO Marcelo Claure has hinted to this network expansion in social media and in pep talks to various Sprint employees. Some of whom have contacted S4GRU after hearing Marcelo’s vague references in meetings about the upcoming expansion. But this is the first time we have received specific information from inside Sprint.
The purpose of these 9,000 new sites is to expand coverage into new markets, add critical rural coverage where high roaming occurs, capture lost coverage from the shutdown of the old Nextel iDEN network, extend coverage to new suburban areas, and densify the network within existing coverage.
This plan is very targeted by market and includes a significant capital spend investment. The affected areas are seen as critical to Sprint for future growth and reduction of operating expenses in key roaming areas.
With the useable area of Sprint’s low frequency spectrum in the SMR 800 band about to expand even to the border areas, thus allowing nationwide coverage, the buildout of new markets and new rural areas has never been more practical or obtainable to Sprint. Allowing for new areas to have a less tight buildout requirement in site density in small towns and along highways and increase signal strength indoors in cities. The new management of Sprint sees this as the point at which they can move forward and accomplish these once seemingly lofty goals.
The juicy details
S4GRU recently received some details of the project from an internal Sprint source, speaking off the record. The current details of the plan breakdown as follows:
- 1,100 - Decommissioned iDEN sites converted for new Sprint CDMA/LTE coverage and increased density in some key under served areas (Dualband and Triband)
- 1,600 – New coverage expansion sites targeting high roaming areas and key identified market expansion areas (Dualband and Triband)
- 800 – New Dualband sites in exurban and new suburban areas places with new or projected population growth
- 500 – New Triband sites in Urban and Suburban areas to infill coverage where 1900 and 2600 currently do not reach or reach well and 800 capacity would also be improved
- 5,000 – New Urban and Suburban TDD-LTE 2600 “Spark” only sites infilling existing coverages for better signal quality, indoor performance, and capacity. It is not known the mix of macro sites and small cell sites.
One exciting part of this addition to S4GRU is capturing decommissioned iDEN sites. This is something that we have long advocated. In a takeoff I did of the iDEN sites back in 2012, I estimated that Sprint needed only approximately 1,000 of the iDEN sites to equalize coverage for the CDMA/LTE network and densify some critical areas of some lacking markets. Like Baton Rouge and Grand Rapids. Perhaps decision makers at Sprint read S4GRU after all? I am happy to see my estimate was quite close to theirs.
Interestingly, there is no mention of Clearwire only sites that are in good locations for Sprint to expand or densify Network Vision CDMA and LTE. Not to mention also the 700+ Clearwire Protection Sites. Many of which are in places Sprint does not currently offer service. Like my corner of the Dakotas.
Project Ocean
In addition to this new Expansion Project, Sprint also already has two existing projects under way for targeted regional expansion based on recent acquisition. In Missouri and Central Illinois, Sprint is working on Project Ocean, which involves adding more than 100 former U.S. Cellular sites. Some of these sites are already online with many more coming online within the next 6-8 months.
The bulk of these adds are in Suburban St. Louis. However, there are a couple dozen rural USCC sites that are also being captured in the Project Ocean program. Sites where demographics are supportive to expansion or high roaming costs make the additional sites worthwhile.
Project Cedar
A thousand miles to the northwest, Sprint is embarking on Project Cedar in Montana. A plan to add 230 sites to the Sprint network in the Treasure State. Sprint purchased the defunct network assets from Chinook Wireless back in August of 2014. Chinook Wireless operated their service under the Cellular One name in Montana. Project Cedar takes the Chinook Wireless decommissioned sites and adds Network Vision DualBand and TriBand sites in their place.
We assume Project Cedar is being done by Samsung, as past geographic maps from Sprint show this area to be Samsung. There was a Field Implementation Test (FIT) for LTE Band 26 (SMR 800MHz) done by Samsung in Montana back in 2013. We never did find out where in Montana this FIT was conducted, and it may even be live for commercial traffic now. S4GRU members travelling in Montana, be on the look out for B26 LTE signals and new Samsung equipment being installed.
In my cursory review, it appears that the footprint offered by Chinook would have been served by 120-140 sites at best using PCS 1900 spacing. Since Sprint is looking to do 90-110 more than that, it’s possible Sprint could be extending service well into the Dakotas and Wyoming under this project. Beyond the reach of the old Cellular One coverage area.
I could see them covering all the Chinook coverage plus I-25, I-90, I-94 in Wyoming and the Dakotas as well as Casper, Gillette, Rapid City, Pierre, Williston and Bismarck with 230 sites. Heck, convert Swiftel’s 50 sites in Eastern South Dakota while you’re at it! Swiftel is a sore subject with us, and we will save that for another day.
Funding and implementation
According to the source, Project Ocean and Project Cedar are already funded. The additional 8,000 site expansion with unknown project name has funding earmarked for its planning and initial start. However funding sources and final scope are being worked out. It is likely Sprint will make no comment on the matter until these last two items are resolved probably next quarter.
However, Sprint is already moving on initial planning and key sites as they come available. No good opportunity will be lost during the planning process. And maybe there are some more regional plans in play?
