NEXTIVITY/ CEL-FI FAQ

Are there any CEL-FI kits that support more than one carrier?

Only the CEL-FI Quatra hardware can support multiple carriers at the same time. All others are carrier specific. This allows them to bypass the standard FCC rules that amplifiers fall under. This includes rules regarding the amplifier gain. While most amplifiers max out around 72dB, the CEL-FI kits max out at 100dB. This increased gain not only results in a potentially stronger signal, but also supports much larger coverage areas (72dB gain systems typically cover up to 6,000 square feet, while the CEL-FI system is capable of up to 13,000 square feet).

Are there any options for external/weatherproof antennas for the CEL-FI PRO or DUO+ kits?

The CEL-FI PRO and DUO+ kits do not support external antennas. If external antennas are needed, check out the CEL-FI Go X system.

Can I use more than one CEL-FI PRO or DUO+ unit if I need to support multiple carriers?

Yes, unlike the traditional cabled kits from SureCall and weBoost, the CEL-FI PRO and DUO+ kits can be used in the same location without causing interference between the systems.

Do any CEL-FI products support FirstNet?

Yes, the CEL-FI GO Red Signal Booster for FirstNet supports FirstNet.

Do the CEL-FI systems require the internet to set them up?

No, you just need an outdoor signal strength with a minimum of one bar (which is where you would mount the outside antenna) along with a smartphone. The phone links to the CEL-FI system via Bluetooth in case any setup or troubleshooting is needed.

How are the CEL-FI PRO and DUO+ systems set up and managed?

The CEL-FI DUO+ and PRO systems are controlled via smartphone app. Both Android and iOS apps are supported.

How does the CEL-FI Go work?

The CEL-FI Go M and X kits work similarly. They will receive a cellular signal, amplify it, and then send the amplified signal to a space within your vehicle or building.

What Cel-Fi products are End of Life (EOL) / Discontinued?

We have a list at Cel-Fi End of Life Products.

What is the difference between the CEL-FI flat panel and dome antennas?

A CEL-FI flat panel antenna is directional with a gain of 6.5dBi to 9dBi.
CEL-FI Dome antennas are omni-directional with a gain of 2.5dBi to 3.5dBi.

Will the CEL-FI systems work on 5G when it becomes available in my area?

CEL-FI antennas are available in many different network configurations, including 5G. Not all CEL-FI are compatible with 5G, however, so be sure to read the product descriptions. If you need assistance, please don�t hesitate to contact 5Gstore.
