How Cell Booster Extended Range Technology (ERT) Works (Video)

Mar 03, 2020

Talk about an entirely new and proven way to boost your cell signal in an innovative and ground-breaking redesign of Surecall’s already patented technology called Extended Range Technology or ERT for short form. We carry ERT cell boosters as well as boosters with Double Power Technology (DPT). Both these have the latest and most advanced cell boosting technology built into them. Watch the video below that illustrates how ERT works.

Extended Range Technology (ERT) Explained:

Today, we're here to talk about an entirely new and proven way to boost your cell signal an innovative and ground-breaking redesign of Surecall's already patented technology. We call this Extended Range Technology or ERT in short. It was designed in their lab over the past several years. It is patented, so you can only find it in Surecall boosters.

What is Extended Range Technology?

Extended Range Technology or ERT is very important because it offers several key advantages over non ERT boosters. Such advantages include faster data speeds, clearer calling, more simultaneous users, larger building or vehicle coverage, and better performance in rural locations. Chief among these benefits are faster data speeds and clearer calling. To understand how this works, consider the following analogy. Imagine you're the lead singer of a rock band and you're throwing a concert. How close would you stand to the microphone? Well, if you want to be heard, you would probably be standing right there, right next to the mic.

What does using a non-ERT booster sound like?

Using a non-ERT booster is like singing from all the way back. How well do you think your screaming fans would hear you? Your voice probably wouldn't carry beyond the first couple of rows. Not only that but you would have all the surrounding noise as well between you and the microphone being picked up, making it difficult not only to be understood - but heard.

What does using an ERT booster sound like?

On other hand, using an ERT booster is like singing directly into the microphone with no distance or interference. An ERT booster can pick up your signal or your voice at its strongest point, where it has the best quality. This means you can be heard and understood throughout the venue. In terms of your cellular device, this means clear voice calls and faster data speeds, as well as boosted uplink and downlink speeds. This gives you better signal both from the device to the tower and from the tower back to your device.

Your signal will be at least two times better quality with ERT.

The difference has to do with noise, meaning electromagnetic noise or interference. Signal strength is measured in decibels or Db for short. With non ERT boosters, you get extra noise as your signal moves through the cable from outside antenna to the booster, like standing several feet away from the microphone. With non-ERT boosters, they do their best signal-to-noise ratio or SNR by using filters, but we found nothing works as well as our ERT solution.

Advantage of higher quality boosted signal.

What you want is a higher quality boosted signal because it gives you clear calls and faster data speeds. ERT boosters give you this higher-quality signal by eliminating the cable loss and its noise, just like standing right next to the microphone. See, with ERT, your signal is collected and boosted as it is received without the cable to spoil your signal down. That higher-quality signal is then sent straight into your inside antenna, which delivers it to your device.

Getting the boosted signal back to the cell tower.

For you, this better quality signal means reliable calls and fast data, see the difference! Speed and reliability are what we want, right, but your booster's job isn't done yet. Now, we have got to get your boosted signal back to the cell tower. This is called coupling. As your signal travels from your phone back to the inside antenna and booster, the ERT technology avoids the cable for a second time, so you don't get added noise. This higher-quality uplink signal has what it needs to travel back to the tower even far away. So when we say Surecall's ERT boosters can give you much better service and signal strength in a wider range of locations, this is what we mean.

SignalBooster.com carries ERT cell phone boosters as well as DPT boosters (cellular amplifiers with Double Power Technology). Both these have the latest and most advanced patented cell phone signal amplifying technology built into them.

  • Voice quality is key for me. This ERT technology looks promising. If this really works it will be worth every dollar if it really is the high quality boosted signal it promises. Can’t wait to check it out and put it in my car.

  • I like using my cell phone in the car when I’m on long trips (which hasn’t been much lately, but then again, most people haven’t been going out due to the current health situation). When I do though, I like having clear audio. Fast data speeds are nice but when I’m in my SUV, I want to be able to hear the other person clearly and have them hear me like I’m in the same room. That’s why ERT sounds like it’s worth checking out.

  • One of the biggest complaints people have in rural areas is the poor cell reception. Now, with people stuck at home, it’s even more of a concern. I think ERT boosters might be a solution since they help reach towers that are further away. A booster is no good if it can’t reach a tower (as boosters can’t amplify non-existent signals).

  • I liked how this blogger used the singer analogy. It gave me a better perspective on why someone might want an extended range booster. Technical blogs like this are so much easier to understand than some of the other ones you see online that make it seem like they’re written for engineers.
