Difference between cell "signal strength" and "signal quality".
What is the difference between Strength and Quality of a Cell Phone Signal?
"Signal strength" is how strong the signal you're receiving is, and it is measured in dBm. The closer your cell device is to the cellular tower transmitter, the more signal your cell phone or Mi-Fi antenna will pick up. The farther away from the tower your cellphone or MiFi is, the more your signal level will drop and you may need a signal booster kit to compensate.
On other hand, "signal quality" is measured by how noisy a band is. In essence, "signal quality" is like how much water there is (voice and data transmission capability), versus how many waves are in the water (noise that disrupts, distorts, or alters the core transmission). Quality is how much interference there is between the cell tower and your cellular device. It is how good the signal is that you receive or how good it will keep during rainy, snowy, or stormy conditions. All signals hold reflections, ghosting, or interference that we call "noise". Noise is what causes cell phone voice calls to not sound realistic as they do in real life. The noise is considered to be low if the quality is high or good.
A typical cell phone signal booster will boost everything. It will boost the strength of the receiving signals including amplification of the noise, interference and the bad quality. Overall, it works well because majority of transmissions consist of voice transmissions and Internet data so it boosts all of that along with minor amount of noise that exists within the signal arriving from the mobile carrier's cell tower.
Can simply signal quality amplified?
Signal quality amplification vs. noise amplification is possible by using technologies such as the one included in some proprietary kits: Extended Range Technology (ERT) and Double Power Technology (DPT). SureCall has pioneered with exclusively patented ERT in their ERT amplifiers and patented DPT in their DPT amplifiers. ERT and DPT allows SureCall cellular amps. to offer additional critical performance benefits on phone signals including twice the power for uplink, downlink gain, and higher Signal to Noise Ratio (SNR) - particularly for multiple users, signal speed and signal quality. Those signal amplifiers also ensure that the connection stays robust even with weak signals outside that create dead zones inside.
Takeaway:
There're cellular amplifiers that boost signal as well as noise. However, if you're where signals are extremely weak outside, the best cell phone signal booster is the one that filters out noise to maximum extent possible. Boosters at links in preceding paragraph have built-in technology that does just that. That reduced noise for better signal quality technology is patented and not found in other cellular amplifiers.
