Which view is wrong about the challenges of network construction and responses to 5G wireless side site changes? (single-choice question, 10 points)
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
