If they migrate all customers to PCS and AWS they better have a state of the art small cell network in every city since that is what Verizon did with their PCS and AWS holdings here in New York City and congestion is a thing of the past.
This merger is the most idiotic decision in the history of the business, especially when the 5G era is about to begin and Sprint was going to have the upper hand.
You know that after the merger is approved, all of Sprint's customers will be migrated over to PCS and AWS and off band 41, which then becomes the primary band for 5G. There will be plenty of upload bandwidth in midband particularly if they can get PCS more contiguous.
Sector IDs (per my own experience and reports):
01-06 850 MHz (CLR)
08-0D 1.9 GHz (PCS)
0F-14 700 MHz (lower 700)
16-1B 2.1/1.7 GHz (AWS)
95-9A 2.3 GHz (WCS)
D7-DC 700 MHz (upper 700--some areas)
DD-E2 700 MHz (upper 700--some areas)
As of this writing, I'm going from memory and will try to add more information from my logs later in the day.
