Direct comparison on the metrics that matter most in DOT procurement and deployment decisions: resilience, range, total cost, and certifications.
Every feature below reflects real-world deployment priorities identified by fire departments, EMS agencies, and municipal DOT procurement teams.

This is the single most important differentiator for emergency response departments. Cellular networks are consistently degraded or saturated during the exact events that generate the highest emergency call volumes: hurricanes, major fires, mass casualty incidents, and infrastructure failures.
Competing preemption technologies depend on those same cellular networks. ELiMiNATOR® uses a 900 MHz FHSS encrypted radio mesh as its primary link — operating through hurricanes, major power outages, and network saturation events. Cellular is available as an optional enhancement but never required for core preemption.
No mandatory SIM cards. No required data plan. No forced carrier fees. Add cellular where it helps — or run fully on the encrypted radio mesh. Either way, the system costs less to buy and less to run.
Encrypted frequency-hopping mesh radio for secure, reliable transmission.
Operates through power outages and network saturation events.
Direct vehicle-to-intersection radio. No cloud round-trip required.
SIM cards and carrier contracts are never required. Add cellular only when your deployment benefits from it.
No. The ELiMiNATOR® operates entirely on 900 MHz FHSS encrypted radio. No cellular network, SIM card, or internet connection is required for preemption. Optional WiFi/cellular modules are available for cloud dashboard connectivity but are not required for the core preemption function.
The primary differences are transmission method and disaster resilience. Optical infrared systems use line-of-sight communication — blocked by weather and obstructions. Cellular-based GPS systems depend on carrier network availability during disasters. ELiMiNATOR® uses GPS + encrypted 900 MHz radio, operating up to 3 miles without line-of-sight, in all weather, with optional cellular.
ELiMiNATOR® vehicles use a dual-positioning system combining GPS with an onboard IMU (Inertial Measurement Unit). When GPS triangulation is limited by tall structures or tunnels, the IMU provides inertial positioning backup — ensuring reliable operation in dense urban environments.
SC Teknologies is currently DOT-approved in multiple states, with approvals pending in other states and US territories. We are actively expanding approvals nationwide. Contact us for current approval status in your state and to begin the approval process.
No. The ELiMiNATOR® Phase Selector installs directly into existing NEMA TS-2 traffic signal cabinets — the same standard used by most municipal infrastructure in the US. In most cases, existing cabinet wiring and controller connections are reused, reducing installation time and cost significantly.
