STAY CONNECTED WHEREVER YOU ARE
Deliver reliable cellular connectivity in your building
Staying connected is not just a luxury; it’s a necessity. Tenants, employees, customers, and guests expect their devices to connect reliably – don’t disappoint them.

AT&I’s in-building CEL-FI cellular solutions bring the power of the networks inside your building
Eliminate dropped calls and lagging internet and improve cell reception with a cellular repeater system
Cellular repeaters keep patrons connected by bringing signals from the outdoors into the building, negating the attenuation of RF signals caused by the building materials.
What can a Cellular Repeater do for you?

Eliminate Coverage Gaps
Most modern buildings have cellular coverage gaps - but your building doesn’t have to be one of them. Several factors can impact signal strength by the time it reaches you:
- Cell Tower Proximity
- Exterior Obstructions
- The Building Itself
Not being connected can raise stress levels, reduce productivity, and slow transactions. While Wi-Fi can help, it’s not a substitute. You need both!

Improve your building's cell connectivity
A strong, reliable, cellular signal throughout your facility benefits people and operations:
- Stay Connected: Keep employees, customers, and visitors connected and able to take care of business
- Convenience: Make it easy and convenient for customers to access information to enhance their experience
- SafetyEnhance security by enabling everyone to reach emergency services if needed

How it works
A cellular repeater system is typically made up of three primary components:
- A "donor" antenna - also called a "reception" antenna
- A bi-directional signal amplifier
- One or more rebroadcast antennas
