DESIGNED FOR YOUR OPERATION

## Hardware capabilities for real operations.

01 / CAPABILITY

### Single-station linear positioning

Track progress along a corridor; this does not imply single-station 2D or 3D positioning.

02 / CAPABILITY

### Installation hardware

Brackets, pole clamps and two directional antennas support corridor deployments.

03 / CAPABILITY

### Unified power and backhaul

PoE carries power and data over one cable, with centralized management.
