# How far can the sensors be installed away from the smart hub?

The transmission range of the Noorio sensors in an open environment can reach up to 656 ft (200m), or go across 3 walls. However, the actual range could vary depending on the following conditions.

1. Building materials & structures: Reinforced concrete could block more singal compared to wood.

2. Obstacles in rooms: Furniture, doors, and windows could potentially reduce the transmission range.

3. Installation location of the Smart Hub: If the Smart Hub was installed in a corner, or blocked by other obstacles, it could affect the transmission range.
