Utilities planning AMI 2.0 deployments often face a difficult choice between the scale of public cellular networks and the reliability of private infrastructure. While NB-IoT offers cost-effective wide-area coverage, it often struggles with deep indoor penetration and network congestion. Conversely, Private Sub-1GHz (like Weightless) offers deterministic control but requires capital investment. The optimal engineering solution is not choosing one over the other, but implementing an architecture that integrates both to eliminate single points of failure.
