This solution is used within the U.S.. It combines standards associated with US: NTCIP Environmental Sensors with those for I–M: Wireless SNMPv3/TLS. The US: NTCIP Environmental Sensors standards include upper–layer standards required to implement center–to–field weather and environmental sensor communications. The I–M: Wireless SNMPv3/TLS standards include lower–layer standards that support secure infrastructure–to–mobile communications using simple network management protocol (SNMPv3).

One significant or possibly a couple minor issues. For existing deployments, the chosen solution likely has identified security or management issues not addressed by the communications solution. Deployers should consider additional security measures, such as communications link and physical security as part of these solutions. They should also review the management issues to see if they are relevant to their deployment and would require mitigation. For new deployments, the deployment efforts should consider a path to addressing these issues as a part of their design activities. The solution does not by itself provide a fully secure implementation without additional work.
