Difference between ERT and Non ERT Cell Phone Signal Boosters

Is there any advantage of using Extended Range Technology (ERT) cell phone boosters over Non-ERT cellular phone signal amplifiers? Are you promised the ability to evade signal loss in a cable with ERT or not? Are faster download signal speeds guaranteed with ERT cellular boosters? How do ERT and Non-ERT cell phone signal boosters compare?

Well, it is never easy getting a proper cell phone signal in remote areas, particularly when your Smartphone only shows a single bar signal strength. Clearly, it is almost an unsaid rule that signal strength bars between 1 and 5 are the way we measure the signal for data and voice connections on our mobile phones. As a result, signal speed/signal quality and signal strength are almost seen as one and the same. But this shouldn't be so! If you understood signal speed (signal quality) you should have no problem understanding cell phone connectivity much better.

Understanding signal speed / quality and signal strength.

Signal strength connectivity bars on your mobile device are important if they tell you about quality of the signal. It is when text messages aren't going through, Internet speeds are slow and videos are interrupted intermittently characterized by unsettling buffering that you realize your internet speed is really slow or unavailable. However, the question is whether 5 or 4 bars are much better than 3 or 2 bars and if signal strength really translates into better signal quality.

Signal speed/quality and signal strength in perspective.

SNR (Signal-to-Noise Ratio) or generally signal quality is calculated using signal strength and noise strength ratio logarithm. Here, the noise is typically electromagnetic noise and a critical constituent of all manner of objects from anything like thermal noise, manmade objects, cosmic and atmospheric objects to channel interferences. Electronic signals are ever in competition with noise and higher Signal-to-Noise Ratio has been ascertained to offer better data speeds and signal quality. On the other hand, very low Signal-to-Noise Ratio has been found to affect data speeds incredibly, no matter the strength of the prevailing signal.

Even so, it is worth noting that 1-5 signal strength bars on Smartphones doesn't mean better data speed; SNR or signal quality really affects signal speed. In fact, signal speed is virtually unhindered in any way by signal strength.

Signal Strength vs Noise

Of course a single signal strength bar on a phone usually doesn't encourage Internet connection but a signal strength that is low leads to low SNR. If electromagnetic noise wasn't there, the level of a weak signal received wouldn't be easy to decipher, including its effect on signal speed considering SNR wouldn’t be any lower.

As shown in the diagram, when signal strength is almost on the noise floor, which translates into 1-bar scenario on a phone, the Internet connection would definitely terminate. Even so, a signal strength that can be considered higher on its own won't raise data speeds as Scenario #4 shows, since when both noise floor and signal strength are high the internet speed will stop or slow down.

As such, to boost cellular data speeds SNR or signal quality must be maximized. This can be done through enhancing the signal strength for those with 1-2 bars only or through ensuring noise floor has been lowered.

Signal quality really matters.

In a perfect scenario usually hard to accomplish, both signal speed and signal quality would be high when there's zero signal interference. It is more like in a room where background noise is zero and hearing a person on the other side isn’t a struggle at all. Practically however, such a scenario is only hypothetical and rather hard to come about. Since interferences or electromagnetic forces are ever present in the real world, it means the situation is rather different.

Essentially, cell phones and cell phone signal boosters reach a point where even if you notice 1-3 bar phone signal strength anything between 3-5 signal strength bars seem to have little difference. More like being in a room where the background noises are of a medium range and two people talking must shout a bit louder if at all they would understand one another. However, at a specific noise volume level no matter how loud one is, the conversations would still be hard to carry out even if the conversationalists are shouting loudly.

Essentially, it is more like signal strength being there and perhaps even better, but signal quality very poor and really not helping with communication.

Signal quality is everything, can you boost it though?

Of course you can, courtesy of SureCall pioneering ERT (Extended Range Technology) exclusive patent now included in SureCall signal boosters. ERT allows SureCall cellular amplifiers to offer additional critical performance benefits on cell phone signals, particularly on multiple users, signal speed and signal quality while ensuring that connection remains robust even in dead zones and weak signals.

How does ERT enhance this?

ERT in SureCall cellular boosters ensures that the incoming cell phone signal has an enhanced signal quality through fundamental solutions mandated with the rearrangement of a booster's components. For instance, SNR-measured signal quality within the system is elongated forward via cable lines and booster right into your mobile device and as SNR is increased, it adds to the speed.

As uplink signals leave the phone to the booster and right to the cellular tower closest to you, ERT ensures that the signal is further amplified more than in any other available cellular signal boosting system available today. In the process, you're able to remain connected to the Internet and receive texts and calls perfectly well. In fact, for such vehicle range cell phone signal boosters such as Fusion2Go Max and N-Range - enjoying your data, text and voice calls is assured even in confirmed dead zones inside, and weak-signal locations. Such unique advantages keep ERT SureCall signal boosters above their competition anywhere.

Rather than having a larger booster with additional expensive equipment to enhance the signal quality, ERT ensures the noise floor is lowered effectively and a fast, reliable and robust connection happens. Akin to hushing noise in a room and ensuring that you're able to speak effectively with a person across the room.

How top quality signal is accomplished by ERT.

Boosters equipped with ERT ensure that your cell phone ends up with a higher and reliable quality signal. The engineering of ERT guarantees that since a signal loses its strength while being conducted via cables it is avoided by ensuring signal loss of up to -4dB has been eliminated. In the process, ERT amplifies downlink signal effectively ensuring it is two times better in terms of quality than in typical cell phone signal boosters out there. Essentially, ERT cellular reception boosters also ensure a faster signal speed.

A comparison between ERT and Non-ERT cellular signal boosters offer a better picture (see screenshot at the top).


  • Any cellular signal close to -120dBm depicts a very weak cellular signal.
  • Cellular signal close to -50dBm depict a very strong cellular signal.
  • Whenever SNR is high, faster speed is guaranteed.

From a cellular device towards the cellular tower, the signal passes via the ERT booster, which courtesy of ERT technology avoids cable loss of -4dB thus firing up an uplink signal further. As a result, ERT cellular signal boosters can easily cover diverse geography, including the harshest terrains known to affect cellular signal. ERT boosters are made to work in places where non-ERT or typical cell phone reception boosters have been largely ineffective.

What you should take away from all this?

Once you understand how signal speed or quality and signal strength compare and affect the way you communicate with your mobile devices, ensuring that you get a cellular booster system that works effectively well shouldn't be hard at all. The idea is to place more emphasis on speed tests and less on signal bars on your phone.

The point here is to always be perfectly sure your boosters are giving you the value that you deserve. To do so, you should always carry out speed tests of your Internet through streaming videos or apps such as SpeedOf and Speedtest. In the process you will know how speed does change and play out on your device. Note that these unique benefits of ERT boosters are hugely noticeable in terrains that result in dead zones inside, and weaker reception where signal speed is threatened by noise floor levels.

Example of an ERT Booster: (Fusion2Go Max)

ERT Cell Phone Signal Booster

SureCall's example of ERT effectiveness and reliability is both the N-Range and Fusion2Go Max.

N-Range for instance, is perfect for the solo driver, an entry-level, affordable and reliable cell phone booster. It has a simple design and the easiest to install with ERT enhanced performance.

For simultaneous users in a vehicle, SureCall’s Fusion2Go Max is the top choice for passengers who shouldn't worry about pushing its performance limit much further. The model includes better cellular tower range for vehicles and enhanced Internet speed more than most vehicle cell phone signal boosters out there courtesy of its ERT design.

Like in-building DPT boosters, these cell boosters also have Double Power Technology (DPT) built into them.

  • Extended Range Technology cell phone boosters sound like super cell phone boosters. I can’t say I have a solid grasp on all the concepts here, but the explanations for signal quality, signal strength, etc. helped broaden my knowledge of what is involved in cell phone calls. Thus, in some cases an ERT booster is the booster you’ll want whereas other situations require just a “regular” signal booster.

  • So even though I bought a new phone, upgraded my plan and switched to US Cellular because I’ve always heard they have the best coverage. And even though I right in town only 3 blocks away from a US Cellular store, you’re saying I’m going to have to buy an ERT in order to have consistent internet and be able to hear conversations on my phone?

    I don’t blame you Robin. Do ERT boosters do anything significant? Yes. From what I’ve read, they perform significantly better and you do get what you’re paying for here. If I had a choice, I’d save up and get the ERT rather than the non-ERT.

  • So is it safe to say that ERT boosters do a better overall job than Non-ERT boosters? Just curious because I want to buy a booster, but I want the best one. However, if there’s not much difference, why pay the extra money if they don’t do anything significant?

    Robin Jackson on
  • No idea what either ERT or Non-ERT cell phone boosters are. I’d like to say I understand things better but the only thing I really picked up was the analogy of ERT’s being a “shush” device in a noisy room. I guess that’s a start but I’ve got a looooong way to go before I get a grasp on things.
