There were 3 operations teams at the time of the merger.
-
T-Mobile (Same team covered 2G through 5G)
-
Sprint LTE
-
Sprint IS-41 (CDMA) - Pretty much laid this team off when they shut down CDMA.
Ulf will take what's left, outsource to his buddies at Ericsson again, and then lay off the lot and watch his stock value go up for cutting costs.
On the Bellevue "development" side, there's about 3 folks who actually "design" things. The rest manage the junk that comes out from Ericsson and Nokia. You could lay off almost all Bellevue and nothing bad would happen.
