Questions & Answers

Yes, up to 15,000 sq ft is just an estimate. Many factors will influence the actual coverage area you will see from a repeater, including layout/floorplan, construction, and original un-amplified signal strength. Depending on your situation, you may see more or less coverage than the estimates listed here. It is not possible to guarantee coverage area.

Yes, This amplifier supports 4G LTE, XLTE, and VoLTE (HD Voice) for Verizon only. It is NOT compatible or approved for use with ANY other carrier. It will not help with Verizon 3G, and it will only help with voice/calling if you have HD Voice/VoLTE enabled on your phone and are in an LTE area.

There is no need to reboot either the network or coverage unit. Out of the box the devices will pair automatically and automatically adjust their gain. 5Gstore has had a unit since before the public launch and uses it in our warehouse, and have never had to reboot the unit for any reason in our testing.

There is no suggested maximum distance since all environments are different. Depending on interference, walls, other signals, signal strength the network unit receives from the cell tower, the maximum distance is going to change. Typically you would separate the units as far as possible to achieve the largest coverage from the units. In our 5Gstore warehouse they can be separated by a few hundred feet, but can go much farther since we have mostly open space.

The Cel-Fi is able to work with weaker signals and boost to larger coverage areas thanks to its 30 db additional gain over traditional signal boosters. In order to get this extra gain, the Cel-Fi falls under a new FCC certification for Smart Signal Boosters. Part of these rules is the Cel-Fi can't work on multiple carriers. There are many other multi-carrier amplifier systems but that max out at 70db, not 100db of gain, and require multiple inside antennas to cover the same places a Cel-Fi can completely wirelessly. You would need a different Cel-Fi system if you changed carriers.

It is now available!

No. The Cel-Fi DUO+ is Verizon specific, and it will not boost or interfere with any other cellular carrier signal.

Since the Cel-Fi is rebroadcasting the carriers signal, if you leave the Cel-Fi coverage area, you'll have a seamless handoff to the carriers network without dropping the call. Same works in reverse. You can connect to the carrier and come into range of a Cel-Fi without dropping the call.

The Cel-Fi supports up to 60 simultaneous users at one time.

Yes! Any device running on the Verizon LTE network will benefit including Cradlepoint modems, other embedded Verizon LTE routers, mobile hotspots, USB modems, phones, and more!

This will be available by the end of the month. Please use the signup sheet on the main page to be alerted once this is available.

The Cel-Fi is carrier specific. The Verizon model only work with Verizon devices. There is no Cel-Fi that works with Sprint at this time.

No, they are carrier specific, which 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 to support much larger coverage areas (72db gain systems typically cover up to 6000 sq ft, while the Cel-Fi is capable of up to 13000 sq ft).

Yes, unlike the traditional cabled kits from SureCall and weBoost, the Cel-Fi kits can be used in the same location without causing interference between the systems.
