The thing about building expensive infrastructure is that it is then expensive to maintain, it is a task that can never stop once it is put into use.

Building it would be extremely expensive,

IMO the more interesting thing is if this Huawei issue is not resolved, who is going to build the 5G phones?
QCOM still owns the chip sets.

Seems there has been a 90 day reprieve on Huawei ban. don’t know if this applies to QCOM or not.

Maybe just a negotiating tactic, we will see.
