Which 5G Network is Best: CBRS, DAS or Millimeter Wave?

A study of deployment costs for 5G private networks, comparing use of licensed Citizens Broadband Radio Service (CBRS), millimeter wave (using a mobile operator’s spectrum) and a distributed antenna system approach--with spectrum assets supplied by a mobile operator-- suggests millimeter wave networks are most affordable when high capacity is required.

When lower capacity will suffice, CBRS is the lowest-cost option. The study, conducted by Mobile Experts, is of a private network supporting robots in a factory. 

The lower cost of the millimeter wave option in a high-capacity scenario is the small number of radios (one) compared to the CBRS and DAS alternatives.

But CBRS turns out to be the lowest-cost option when less capacity is required. In either scenario--high or low capacity--DAS was the most-expensive option.
