I've been with Sprint since 2000. T-Mobile's integration of Metro (former CDMA) was considered to be a huge success. I can tell you though, that I've been through Nextel buyout and the famous (not in a positive way) Network Vision, and countless promises of "a better network", so many "Projects" planned and started and very few of them completed. Dr Saw is probably the best head of network Sprint has had in some time. He's going to T-Mo too. I too have heard through tower engineer friend that T-Mo has been buying and storing Massive mimo units for a while... and fully plans on using them when the network conversion starts.
I'd say give T-Mo some time to actually start before doubting them. We don't really know their latest plan. I am looking forward to hearing this and much more news, hopefully beginning Wednesday.
They get had a plan this whole time. TMobile has been buying up tons of massive mimo equipment to deploy it ASAP. AWS,600,700 will go on the Sprint keep sites. Sprints PCS and 2.5 on all TMO sites Sent from my SM-G975U1 using Tapatalk
