Which view is wrong about the challenges of network construction and responses to 5G wireless...

Millimeter waves are used in hotspot areas, and small stations are densely distributed, requiring precise site selection

5G adopts C-band and Massive MIMO, which has wider and better coverage and can greatly reduce the number of base stations

Eliminate old pole stations to get enough stations

The number of stations is increased by 1-10 times, the tower TCO is high, and the maintenance is more complicated
