Some friends of mine who work for sprint told me this......sprint needs to upgrade there 3G network to be almost at par with 4G LTE, once that is complete then 4G LTE is underway. I have been told 2 things either sprint will launch 20% of the city of ABQ in December and late Summer 2014 full 100% 4g lte and I been told full 100 by January 2014. The reason southern & southeastern NM have got 4g lte is the company who is upgrading is working south from El Paso to Denver. A sprint employee told me there servers for the SW USA are in El Paso. I have seen some new tower installs near cottonwood area on the power line towers near Intel. I also was watching some videos on you tube near movies 8 and the video was soooo clear I mean clear, usually that means more Mbps is happening. I also have been receiving faster speeds near cottonwood mall, near 12th st & Indian school, and Montgomery Carlise & San Mateo area.
