Differences in SureCall Flare, Fusion4Home, Fusion5s Signal Boosters

Compare SureCall Flare (SKU SC-Poly-DT-O-Kit), Fusion-4-Home (SKU SC-PolyH-72), and Fusion 5s (SKU SC-PolysH/O-72):

Difference in Gain & Amount of Coverage Area.

The main difference between SureCall Flare / Flare 3.0, Fusion4Home and Fusion5s boosters from layman's perspective is the coverage in sq. ft. that they can provide based on the strength of available outside signal. They basically offer different amounts of "Gain" measured in Decibels (dB Gain). That means how much a cellular amplifier can increase existing outside signal strength measured in dBm (Decibel Milliwatts). They offer different amounts of uplink strength (power of signal from wireless devices sent to cell towers) and downlink strength (power of signal from cell tower to wireless devices).

Such varied factors dictate how much signal amplification can occur to enhance indoor signal reception. For example, Flare & Flare 3.0 can potentially increase signal strength over spaces up to 2,500 sq. ft. (Flare) or 3,000 sq. ft. (Flare 3.0). Therefore, it is intended for small homes. On contrary, Fusion4Home booster kit is for medium sized homes and offices because it boosts coverage up to 5,000 sq. ft. In ascending order, the last one, Fusion5s, is for big homes and offices up to 7000 sq. ft.

Please note that if outside signal strength where exterior antenna can be placed is weaker, then a more powerful booster will be required to extend that inside coverage space. For example, although you need to cover only up to 2500 sq. ft. home (offered by Flare booster) but have extremely weak outside signal strength, you will need the next more powerful booster (Flare 3.0) to extend indoor cellular coverage for the complete home / office.

Difference in Ease of Installation.

Another major difference between Flare 1.0, Flare 3.0 versus Fusion4Home Non-Whip antenna kits and Fusion 5S kits is that Flare versions (as well as Fusion4Home Whip Antenna versions) have built-in interior antenna. This makes it easier to install indoors because there's one less thing to do - No separate inside antenna to install along with its cable run.

  • I had a big takeaway from this article on the various boosters mentioned here. There’s that old adage “not all X are created equal” and although there are probably some companies that are better than others in terms of quality, another big factor is the power of each booster. I’ve read some of the other articles here and it’s very important to make sure you booster isn’t underpowered or overpowered. You can’t just say, “OK, I’ll get SureCall because I like the color.” You need to make certain it’s the right power for your home or apartment in terms of square footage and signal power.

  • I’ve been seeing more reviews and blogs about cell phone boosters that mention you need to measure your signal to make sure you have the right powered booster for your specific needs. Has this been a growing concern with people because I’ve always been told you should measure you signal throughout the home (or business) to see where you need the booster the most.

  • Very important that you measure your signal strength before you look at a cell phone booster. I’m glad this article mentions that a booster for 1000 square feet might not be effective for your 1000 square foot home if you have an extremely weak signal. I’m sure it’ll help somewhat, but you want something that works very well. Likewise, don’t buy a booster that’s too much power for your home. There are many places to get help if you have questions so investigate before you invest in a booster.
