The solution had to establish secure wireless interconnections of building-level, advanced metering to support the Energy Policy Act of 2005 and the Energy Independence and Security Act of 2007. Department of Defense (DoD) installations across the country were included in the scope. The solution additionally required complex and flexible virtual LANs (VLANs) to reduce installation costs and expedite implementation.


More than 5,000 WiFiProtect Access Points from 3eTI were installed as networked systems for measuring energy usage and allocation, as well as for real-time energy resource management, to reduce consumption. These installations now manage energy use, power quality and cost by connecting smart meters to WiFiProtect wireless units. Installation managers estimate energy savings of more than 10 percent with the system.

WiFiProtect delivers a smart-grid mesh network that is wireless and scalable. It can integrate metering technology for advanced metering device management and multi-device modes. The network incorporates bridging, access points for clients, mesh networking and secure encryption. Its rugged design protects against tampering and inclement weather by encasing equipment inside a lockable and rugged enclosure. It supports VLANs, allowing for operation by multiple users with varying levels of authorization.

WiFiProtect is an extensively credentialed offering: IEEE 802.11 standard compliance, Common Criteria EAL Level 4, FIPS validation, NSA Suite B upgradable. It also complies with stringent environmental guidelines that include HERO, HERP and HERF, as well as military standards (MIL-STD) for shock, vibration and electromagnetic interference.
