Preserve Your Full Data Speeds with True MIMO Technology

If you're using a signal booster to Improve 4G LTE & 5G Data Speeds on your devices, using a MIMO system can further increase your data speeds. 

Most signal boosters are "Single Input Single Output" devices that can actually reduce your maximum data rates by around 30%. Your smartphone and cell towers use Multiple Input Multiple Output (MIMO) technology with multiple antennas to maximize bandwidth.

The upgraded version of it's-kind, CEL-FI GO G41 MIMO Kit uses two boosters working in parallel to preserve this MIMO capability, ensuring you get the fastest possible data speeds after boosting.

Powered by the CEL-FI GO G41

The GO G41 is different from the majority of other boosters we sell in 3 ways:

• Single-Carrier Focus: The GO G41 is a single-carrier device and will amplify signal for just one carrier at a time. If you need to boost signal on multiple carriers, you may be interested in the Cel-Fi GO G43, which covers Verizon, AT&T, and T-Mobile simultaneously.

• Highest Gain: The GO G41 offers up to 100 dB gain. Unlike most other boosters, the, it is not restricted to 70 dB gain by the FCC. The extra 30 dB gain makes this the best solution for buildings where outdoor coverage is weak.

• 5G Support: Supports both 5G DSS and 5G NR services.

The CEL-FI GO G41 can boost the following bands:

• AT&T bands: B2/n2, B4/n4, B5/n5, B12/n12
• Verizon bands: B2/n2, B4/n4, B5/n5, B13/n13
• T-Mobile bands: B2/n2, B4/n4, B5/n5, B12/n12

Note: The G41 does not support the n41, n71, or n77 frequency bands used for T-Mobile 5G.

Nextivity WAVE Mobile App

The GO G41 can be optimized and monitored by the Nextivity WAVE application for iOS and Android devices.

Nextivity's WAVE app allows you to connect to the device over bluetooth and see detailed diagnostics, including signal strength (RSRP), gain, bandwidth, and signal quality (SINR).

4G LTE & 5G Support

5G support is more critical than ever, as more carriers open up 5G capability across different frequencies.

The G41 supports 4G LTE, 5G-DSS, and 5G NR out of the box. It will connect to and boost these frequency bands automatically at setup.

Coverage Area 

As with all signal booster kits, the coverage area of the CEL-FI unit depends on two factors:

• The number of indoor antennas you pair it with
• The signal strength at the location where the outdoor "donor" antenna is installed.

Up to 15,000 sq ft coverage is possible in an open area by utilizing 4 indoor antennas. In a typical home or office environment, up to around 3,000 sq ft coverage is possible from a single indoor antenna.

Indoor antennas

Choose from 1, 2, 3, or 4 indoor antennas based on your coverage area. In general, the more antennas you have, the larger the coverage area of the system. Signal passes through cables much more easily than through walls and even through the air, so adding more antennas helps expand the coverage of your booster.

Rule of Thumb:

Typical home or office with interior walls: 

• Install one antenna for every 1,000 to 1,500 sq ft of space

Open environments (warehouse, open office floor)

• Install one antenna for every 1,500 to 3,000 sq ft

MIMO Ultra-Flat Dome Antenna

All the kits include the MIMO Ultra-Flat Dome Antenna  which needs to be installed on the ceiling. It is best for single-story buildings where you have access to a loft or crawl space, or for office buildings with ceiling tiles. A dome antenna's cable comes out of the back of the antenna, so you must have access to the other side of the ceiling to install it.

Dome antennas spread signal in all directions and should be installed central to the building to provide even coverage.
