This morning 9/25/2017 Sprint blanketed the city with 10X10 B25-2
So far no speed increases. There's only two toweresthat they changed the RRUs the rest are transmitting 10x10 with original NV RRUs

Ultimately they will need to choose one of the EPCs and integrate around that. Then each enodeB will need to be pointed to the EPC and each integrated site will need to be assigned to each enodeB. VOLTE and SVRCC/WCDMA fallback will be the voice solution but will take time.

If we take Sprint’s Executives at their word, Sprint is moving expeditiously on the network now that the debt load has been addressed.
